Configuring Basic Settings
For use the router properly, it is necessary for you to change the password of web
configuration for security and adjust primary basic settings.
This chapter explains how to setup a password for an administrator and how to adjust basic
settings for accessing Internet successfully. Be aware that only the administrator can change
the router configuration.
2.1 Changing Password
For security reasons, it is strongly recommend that you set the administrator password for the
router. During the first setup, the router requires no password. If no password is configured,
the router will be open to any user in the LAN or the Internet, and users can log into the router
unlimitedly and change the settings.
To change the password for this device, you have to access into the web browse with default
password first.
1.
Make sure your computer connects to the router correctly.
Notice: You may either simply set up your computer to get IP dynamically
from the router or set up the IP address of the computer to be the same
subnet as the default IP address of Vigor router 192.168.1.1. For the
detailed information, please refer to the later section - Trouble Shooting of
this guide.
2.
Open a web browser on your PC and type http://192.168.1.1. A pop-up window will
open to ask for username and password. Please type default values (both username and
password are Null) on the window for the first time accessing and click OK for next
screen.
3.
Now, the Main Screen will pop up.
Vigor2900 Series User’s Guide

Notice: Some of the settings might not appear as above, because the home
page will change slightly according to the features that your router has.
12
4.
Click Administrator Password Setup from the Basic Setup group.
5.
Enter the login password (the default is blank) on the field of Old Password. Type a new
one in the field of New Password and retype it on the field of Retype New Password.
Then click OK to continue.
6.
Now, the password has been changed. Next time, use the new password to access the
Web Configurator for this router.

Please select the appropriate time zone for the router. Then, click Next.
2.2.1 Selecting Protocol
In the Quick Start Wizard, you can configure the router to access the Internet with different
protocol/modes such as PPPoE, PPTP, L2TP, Static IP or DHCP. The router supports the
DSL WAN interface for Internet access.
2.2.2 PPPoE
PPPoE stands for Point-to-Point Protocol over Ethernet. It relies on two widely accepted
standards: PPP and Ethernet. It connects users through an Ethernet to the Internet with a
common broadband medium, such as a single DSL line, wireless device or cable modem. All
the users over the Ethernet can share a common connection. And the PPPoA stands for
Point-to-Point Protocol over ATM. PPPoA uses the PPP dial-up protocol with ATM as the
transport.
14
Vigor2900 Series User’s Guide
PPPoE is used for most of DSL modem users. All local users can share one PPPoE connection
for accessing the Internet. Your service provider will provide you information about user name,
password, and authentication mode.
If your ISP provides you the PPPoE connection, please select PPPoE for this router. The
following page will be shown:
User Name
Assign a specific valid user name provided by the ISP.
Password
Assign a valid password provided by the ISP.
Retype Password
Retype the password.
Always On
Check this box to allow the router connecting to Internet
forever.
Idle Timeout
Type in the value (unit is second) as the idle timeout of the
connection. When the time is expired, the internet connection
will be dropped immediately.

2.3 LAN TCP/IP and DHCP Server
Basics of LAN
The most generic function of Vigor router is NAT. It creates a private subnet of your own. As
mentioned previously, the router will talk to other public hosts on the Internet by using public
IP address and talking to local hosts by using its private IP address. What NAT does is to
translate the packets from public IP address to private IP address to forward the right packets
to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that assigns
private IP address to each local host. See the following diagram for a briefly understanding.
In some special case, you may have a public IP subnet from your ISP such as
220.135.240.0/24. This means that you can set up a public subnet or call second subnet that
each host is equipped with a public IP address. As a part of the public subnet, the Vigor router
22
Vigor2900 Series User’s Guide
will serve for IP routing to help hosts in the public subnet to communicate with other public
hosts or servers outside. Therefore, the router should be set as the gateway for public hosts.
What is Routing Information Protocol (RIP)
Vigor router will exchange routing information with neighboring routers using the RIP to
accomplish IP routing. This allows users to change the information of the router such as IP
address and the routers will automatically inform for each other.
What is Static Route
When you have several subnets in your LAN, sometimes a more effective and quicker way for
connection is the Static routes function rather than other method. You may simply set rules to
forward data from one specified subnet to another specified subnet without the presence of
RIP.
Vigor2900 Series User’s Guide
23
What are Virtual LANs
You can group local hosts by physical ports and create up to 4 virtual LANs. To manage the
communication between different groups, please set up rules in Virtual LAN (VLAN) function
and the rate of each.
Web Page Configuration
This page provides you the general settings for LAN.
Click LAN to open the LAN settings page and choose General Setup.
24
1st IP Address
Type in private IP address for connecting to a local private network
(Default: 192.168.1.1).
1st Subnet Mask
Type in an address code that determines the size of the network.
(Default: 255.255.255.0/ 24)
For IP Routing Usage
Click Enable to invoke this function. The default setting is Disable.
2nd IP Address
Type in secondary IP address for connecting to a subnet.
(Default: 192.168.2.1)
2nd Subnet Mask
An address code that determines the size of the network.
(Default: 255.255.255.0/ 24)
Vigor2900 Series User’s Guide
2nd DHCP Server
You can configure the router to serve as a DHCP server for the 2nd
subnet.
Start IP Address: Enter a value of the IP address pool for the DHCP
server to start with when issuing IP addresses. If the 2nd IP address
of your router is 220.135.240.1, the starting IP address must be
220.135.240.2 or greater, but smaller than 220.135.240.254.
IP Pool Counts: Enter the number of IP addresses in the pool. The
maximum is 10. For example, if you type 3 and the 2nd IP address of
your router is 220.135.240.1, the range of IP address by the DHCP
server will be from 220.135.240.2 to 220.135.240.4.
MAC Address: Enter the MAC Address of the host one by one and
click Add to create a list of hosts to be assigned, deleted or edited IP
address from above pool. Set a list of MAC Address for 2nd DHCP
server will help router to assign the correct IP address of the correct
subnet to the correct host. So those hosts in 2nd subnet won’t get an
IP address belonging to 1st subnet.
RIP Protocol Control
Disable deactivates the RIP protocol. It will lead to a stoppage of the
exchange of routing information between routers. (Default)
1st Subnet - Select the router to change the RIP information of the
1st subnet with neighboring routers.
2nd Subnet - Select the router to change the RIP information of the
2nd subnet with neighboring routers.
DHCP Server
Configuration
Vigor2900 Series User’s Guide
DHCP stands for Dynamic Host Configuration Protocol. The
router by factory default acts a DHCP server for your network so it
automatically dispatch related IP settings to any local user
configured as a DHCP client. It is highly recommended that you
leave the router enabled as a DHCP server if you do not have a
25
DHCP server for your network.
If you want to use another DHCP server in the network other than
the Vigor Router’s, you can let Relay Agent help you to redirect the
DHCP request to the specified location.
Enable Server - Let the router assign IP address to every host in the
LAN.
Disable Server – Let you manually assign IP address to every host
in the LAN.
Relay Agent – (1st subnet/2nd subnet) Specify which subnet that
DHCP server is located the relay agent should redirect the DHCP
request to.
Start IP Address - Enter a value of the IP address pool for the
DHCP server to start with when issuing IP addresses. If the 1st IP
address of your router is 192.168.1.1, the starting IP address must be
192.168.1.2 or greater, but smaller than 192.168.1.254.
IP Pool Counts - Enter the maximum number of PCs that you want
the DHCP server to assign IP addresses to. The default is 50 and the
maximum is 253.
Gateway IP Address - Enter a value of the gateway IP address for
the DHCP server. The value is usually as same as the 1st IP address
of the router, which means the router is the default gateway.
DHCP Server IP Address for Relay Agent - Set the IP address of
the DHCP server you are going to use so the Relay Agent can help to
forward the DHCP request to the DHCP server.
DNS Server
Configuration
DNS stands for Domain Name System. Every Internet host must
have a unique IP address, also they may have a human-friendly,
easy to remember name such as www.yahoo.com. The DNS server
converts the user-friendly name into its equivalent IP address.
Primary IP Address -You must specify a DNS server IP address
here because your ISP should provide you with usually more than
one DNS Server. If your ISP does not provide it, the router will
automatically apply default DNS Server IP address: 194.109.6.66 to
this field.
Secondary IP Address - You can specify secondary DNS server IP
address here because your ISP often provides you more than one
DNS Server. If your ISP does not provide it, the router will
automatically apply default secondary DNS Server IP address:
194.98.0.1 to this field.
The default DNS Server IP address can be found via Online Status:
If both the Primary IP and Secondary IP Address fields are left empty,
the router will assign its own IP address to local users as a DNS
proxy server and maintain a DNS cache.
If the IP address of a domain name is already in the DNS cache, the
router will resolve the domain name immediately. Otherwise, the
router forwards the DNS query packet to the external DNS server by
establishing a WAN (e.g. DSL/Cable) connection.
There are two common scenarios of LAN settings that stated in Chapter 4. For the
configuration examples, please refer to that chapter to get more information for your necessity.

Vigor2900 Series User’s Guide
2.4 ISDN Setup
ISDN stands for Integrated Services Digital Network. It is an international communications
standard for sending voice, video, and data over digital telephone lines or normal telephone
wires.
Note: The following is available for Vigor2900VGi/Vi only.
ISDN Port
Click Enable to open the ISDN port and Disable to close
it.
Country Code
For proper operation on your local ISDN network, you
should choose the correct country code.
Own Number
Enter your ISDN number. Every outgoing call will carry
the number to the receiver.
MSN Numbers for the Router
MSN Numbers mean that the router is able to accept only
number-matched incoming calls. In addition, MSN
services should be supported by local ISDN network
provider. The router provides three fields for MSN
numbers. Note that MSN services must be acquired from
your local telecommunication operators. By default, MSN
function is disabled. If you leave the fields blank, all
incoming calls will be accepted without number matching.
Blocked MSN Numbers for the Enter the specified MSN number into the fields to
prevent the router from dialing the specific MSN
router
number.
For example, DrayTek provides the Remote Activation (refer to section 3.2) feature for the
teleworkers who wish to dial in the head office over the ISDN. With this feature, teleworkers
can make a phone call to the router at the head office and ask the router to dial up the ISP. As
a result, the teleworkers can be authorized with their office accounts to utilize ISDN dial-up
services and both sides can thus engage in secure communication over the LAN-to-LAN
ISDN.
The ISDN interface of Vigor2900VGi and Vigor2900Vi routers supports the VTA (Virtual
Terminal Adapter, please refer to section 2.8) feature. VTA is actually a “CAPI” software,
Vigor2900 Series User’s Guide
27
which can simulate a real ISDN terminal adapter installed on your computer. You can install
the CAPI-compliant software for dial-up networking, fax or voice applications depending on
the functionality of the CAPI software you installed. To employ the VTA feature, please
download the VTA drivers (available only to Windows 98SE/2000/XP) from
http://www.draytek.com/english/support/download.php.
2.5 Wireless LAN Setup
Note: The following is available for G models only.
2.5.1 Basic Concepts
Over recent years, the market for wireless communications has enjoyed tremendous growth.
Wireless technology now reaches or is capable of reaching virtually every location on the
surface of the earth. Hundreds of millions of people exchange information every day via
wireless communication products. The Vigor G model, a.k.a. Vigor wireless router, is
designed for maximum flexibility and efficiency of a small office/home. Any authorized staff
can bring a built-in WLAN client PDA or notebook into a meeting room for conference
without laying a clot of LAN cable or drilling holes everywhere. Wireless LAN enables high
mobility so WLAN users can simultaneously access all LAN facilities just like on a wired
LAN as well as Internet access.
The Vigor wireless routers are equipped with a wireless LAN interface compliant with the
standard IEEE 802.11g protocol. To boost its performance further, the Vigor Router is also
loaded with advanced wireless technology Super G TM to lift up data rate up to 108 Mbps*.
Hence, you can finally smoothly enjoy stream music and video.
Note: * The actual data throughput will vary according to the network conditions
and environmental factors, including volume of network traffic, network overhead
and building materials.
In an Infrastructure Mode of wireless network, Vigor wireless router plays a role as an Access
Point (AP) connecting to lots of wireless clients or Stations (STA). All the STAs will share the
same Internet connection via Vigor wireless router. The General Settings will set up the
information of this wireless network, including its SSID as identification, located channel etc.

Vigor2900 Series User’s Guide
Security Overview
Real-time Hardware Encryption: Vigor Router is equipped with a hardware AES encryption
engine so it can apply the highest protection to your data without influencing user experience.
Complete Security Standard Selection: To ensure the security and privacy of your wireless
communication, we provide several prevailing standards on market.
WEP (Wired Equivalent Privacy) is a legacy method to encrypt each frame transmitted via
radio using either a 64-bit or128-bit key. Usually access point will preset a set of four keys and
it will communicate with each station using only one out of the four keys.
WPA(Wi-Fi Protected Access), the most dominating security mechanism in industry, is
separated into two categories: WPA-personal or called WPA Pre-Share Key (WPA/PSK), and
WPA-Enterprise or called WPA/802.1x.
In WPA-Personal, a pre-defined key is used for encryption during data transmission. WPA
applies Temporal Key Integrity Protocol (TKIP) for data encryption while WPA2 applies AES.
The WPA-Enterprise combines not only encryption but also authentication.
Since WEP has been proved vulnerable, you may consider using WPA for the most secure
connection. You should select the appropriate security mechanism according to your needs.
No matter which security suite you select, they all will enhance the over-the-air data
protection and /or privacy on your wireless network. The Vigor wireless router is very flexible
and can support multiple secure connections with both WEP and WPA at the same time.
Example 1
Example 2
Vigor2900 Series User’s Guide

Example 3
Separate the Wireless and the Wired LAN- WLAN Isolation enables you to isolate your
wireless LAN from wired LAN for either quarantine or limit access reasons. To isolate means
neither of the parties can access each other. To elaborate an example for business use, you
may set up a wireless LAN for visitors only so they can connect to Internet without hassle of
the confidential information leakage. For a more flexible deployment, you may add a filter of
MAC address to isolate single user’s access from wired LAN.
Manage Wireless Stations - Station List will display all the station in your wireless network
and the status of their connection.
Click Wireless LAN Setup from the Basic Setup group. You will see the following page.

wireless LAN. Depending on the wireless utility, the user
may only see the information except SSID or just cannot
see any thing about Vigor wireless router while site
surveying.
Long Preamble
This option is to define the length of the sync field in a
802.11 packet. Most modern wireless network uses short
preamble with 56 bit sync filed instead of long preamble
with 128 bit sync field. However, some original 11b
wireless network devices only support long preamble.
Check it to use Long Preamble if needed to communicate
with this kind of devices.

2.6 Internet Access Setup
Quick Start Wizard offers user an easy method to quick setup the connection mode for the
router. Moreover, if you want to adjust more settings for different WAN modes, please go to
Quick Setup group and click the Internet Access Setup link. This section will introduce
some basic concepts of Internet and explain the connection modes in details.
2.6.1 Basics of Internet Protocol (IP) Network
IP means Internet Protocol. Every device in an IP-based Network including routers, print
server, and host PCs, needs an IP address to identify its location on the network. To avoid
address conflicts, IP addresses are publicly registered with the Network Information Centre
(NIC). Having a unique IP address is mandatory for those devices participated in the public
network but not in the private TCP/IP local area networks (LANs), such as host PCs under the
management of a router since they do not need to be accessed by the public. Hence, the NIC
has reserved certain addresses that will never be registered publicly. These are known as
private IP addresses, and are listed in the following ranges:
From 10.0.0.0 to 10.255.255.255
From 172.16.0.0 to 172.31.255.255
From 192.168.0.0 to 192.168.255.255
What are Public IP Address and Private IP Address
As the router plays a role to manage and further protect its LAN, it interconnects groups of
host PCs. Each of them has a private IP address assigned by the built-in DHCP server of the
Vigor router. The router itself will also use the default private IP address: 192.168.1.1 to
communicate with the local hosts. Meanwhile, Vigor router will communicate with other
network devices through a public IP address. When the data flow passing through, the
Network Address Translation (NAT) function of the router will dedicate to translate
public/private addresses, and the packets will be delivered to the correct host PC in the local
area network. Thus, all the host PCs can share a common Internet connection.
Get Your Public IP Address from ISP
To acquire a public IP address from your ISP for Vigor router as a customer premises
equipment, there are three common protocols: Point to Point Protocol over Ethernet
(PPPoE), PPPoA and MPoA. Multi-PVC is provided for more advanced setup of the above.
In ADSL deployment, the PPP (Point to Point)-style authentication and authorization is
required for bridging customer premises equipment (CPE). Point to Point Protocol over
Ethernet (PPPoE) connects a network of hosts via an access device to a remote access
concentrator or aggregation concentrator. This implementation provides users with significant
ease of use. Meanwhile it provides access control, billing, and type of service according to
user requirement.
When a router begins to connect to your ISP, a serial of discovery process will occur to ask for
a connection. Then a session will be created. Your user ID and password is authenticated via
PAP or CHAP with RADIUS authentication system. And your IP address, DNS server, and
other related information will usually be assigned by your ISP.
In the Quick Setup field, you can configure the router for different connection types, such as
ISDN, PPPoE, PPTP, Dynamic/Static IP or Broadband Access with ISDN dial backup. Note
that the types of ISDN and Broadband Access with ISDN dial backup are available only to
Vigor routers with the ISDN interface (e.g. Vigor2900VGi).
Click Internet Access Setup on the Quick Setup page. You will access the following page.
Vigor2900 Series User’s Guide

use the same physical type; otherwise, the connection might be
failed due to inconsistent type. It is recommended for you to set
Auto negotiation as the physical type.
After finishing all the settings here, please click OK to activate them.
2.6.3 Static or Dynamic IP
For static IP mode, you usually receive a fixed public IP address or a public subnet, namely
multiple public IP addresses from your DSL or Cable ISP service providers. In most cases, a
Cable service provider will offer a fixed public IP, while a DSL service provider will offer a
public subnet. If you have a public subnet, you could assign an IP address or many IP address

2.7 Virtual TA (Remote CAPI) Setup
Note: This setting is available for i models only.
Virtual TA means the local hosts or PCs in the network that uses popular CAPI-based
software such as RVS-COM or BVRP to access the router as a local ISDN TA for sending or
receiving FAX messages over the ISDN line. Basically, it is a client/server network model.
The built-in Virtual TA server handles the establishment and release of connections. The
Virtual TA client, which is installed on the local hosts or PCs, creates a CAPI-based driver to
relay all CAPI messages between the applications and the router CAPI module. Before
describing the configuration of Virtual TA in the Vigor routers, please notice the following
limitations.
z
The Virtual TA client only supports MicrosoftTM Windows 95 OSR2.1/98/98SE/Me/2000
platforms.
Vigor2900 Series User’s Guide
49
z
The Virtual TA client only supports the CAPI 2.0 protocol and has no built-in FAX
engine.
z
One ISDN BRI interface has two B channels. The maximum number of active clients is
also two.
z
Before you configure the Virtual TA, you must set the correct country code.
As depicted in the above application scenario, the Virtual TA client can make an outgoing call
or accept an incoming call to/from a peer FAX machine or ISDN TA, etc.
Before you configure the Virtual TA (Remote CAPI) Setup, please install the virtual TA client
first. Simply insert the CD bundled with your Vigor router, or directly double-click one of the
installer files. In which Vsetup95.exe is for Windows 95 OSR2.1 or higher; Vsetup98.exe is
for Windows 98, 98SE and Me; and Vsetup2k.exe is for Windows 2000. Follow the on-screen
instructions of the installer. The last step will ask you to restart your computer. Click OK to
restart your computer.
After the computer restarts, you will see a VT icon in the taskbar (usually in the bottom-right
of the screen, near the clock) as shown below.
When the icon text is GREEN, the Virtual TA client is connected to the Virtual TA server and
you can launch your CAPI-based software to use the client to access the router. Please read
your software user guide for detailed configuration. If the icon text is RED, it means the client
has lost the connection to the server. In such condition, please check the physical Ethernet
connection.
Next, click the Virtual TA (Remote CAPI) Setup link in the Quick Setup group to configure
the Virtual TA features.
Since the Virtual TA application is a client/server network model, you must configure it on
both ends to run properly your Virtual TA application.
By default, the Virtual TA server is enabled and the Username/Password fields are left blank.
Any Virtual TA client may login to the server. Once a single Username/Password field has
been filled in, the Virtual TA server will only allow clients with a valid Username/Password to
login. The screen of Virtual TA configuration is presented below.

MSN Configuration
If you have applied to an MSN number service, the Virtual TA server can assign which client
has the specified MSN number. When an incoming call arrives, the server will inform the
appropriate client. Now we set an example to describe the configuration of the MSN number.
Suppose that you could assign the MSN number 123 to the client “alan”.
Type the specified MSN number in the CAPI-based software. When the Virtual TA server
sends an alert signal to the specified Virtual TA client, the CAPI-based software will also
receive the action, the software will not accept the incoming call.

Advanced Web Configuration
After finished basic configuration of the router, you can access Internet with ease. For the
people who want to adjust more setting for suiting his/her request, please refer to this chapter
for getting detailed information about the advanced configuration of this router. As for other
examples of application, please refer to chapter 4.
3.1 Dynamic DNS Setup
The ISP often provides you with a dynamic IP address when you connect to the Internet via
your ISP. It means that the public IP address assigned to your router changes each time you
access the Internet. The Dynamic DNS feature lets you assign a domain name to a dynamic
WAN IP address. It allows the router to update its online WAN IP address mappings on the
specified Dynamic DNS server. Once the router is online, you will be able to use the
registered domain name to access the router or internal virtual servers from the Internet. It is
particularly helpful if you host a web server, FTP server, or other server behind the router.
Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the
DDNS service providers. The router provides up to three accounts from three different DDNS
service providers. Basically, Vigor routers are compatible with the DDNS services supplied by
most popular DDNS service providers such as www.dyndns.org, www.no-ip.com,
www.dtdns.com, www.changeip.com, www.dynamic- nameserver.com. You should visit
their websites to register your own domain name for the router.

3.2 Call Control and PPP/MP Setup
Some applications require that the router (only for the i models) be remotely activated, or be
able to dial up to the ISP via the ISDN interface. Vigor routers provide this feature which
allows you to make a phone call to the router and then ask it to dial up to the ISP. Accordingly,
you can access your remote network to retrieve resources. Of course, you should have a fixed
IP address and expose some internal network resources to the outside world, such as FTP,
WWW and so on.
Note: Call Control and PPP/MP are only available for the models of Vigor2900VGi
and Vigor2900Vi equipped with the ISDN interface.
Click Call Control and PPP/MP Setup from Advanced Setup group.
Note: Please set Dialing to a Single ISP first before configuring this web page.
Dial Retry
It specifies the dial retry counts per triggered packet. A
triggered packet is the packet whose destination is outside the
local network. The default setting is no dial retry. If set to 5, for
each triggered packet, the router will dial 5 times until it is
connected to the ISP or remote access router.
Dial Delay Interval
It specifies the interval between dialup retries. By default, the
interval is 0 second.
Remote Activation
It specifies a phone number in the Remote Activation field to
enable the remote activation function. If the router accepts a call
from the number 12345678, it will terminate the incoming call
immediately and dial to the ISP.
Link Type
Because ISDN has two B channels (64Kbps/per channel), you
can specify whether you would like to have single B channel,
two B channels or BOD (Bandwidth on Demand). Four options
are available: Link Disable, Dialup 64Kbps, Dialup 128Kbps,
Dialup BOD.
Vigor2900 Series User’s Guide
55
PPP Authentication
It specifies the PPP authentication method for PPP/MP
connections. Normally you can set it to PAP/CHAP for better
compatibility.
TCP Header Compression
VJ Compression - It is used for TCP/IP protocol header
compression. Normally it is set to None to improve bandwidth
utilization.
Idle Timeout
Because our IDSN link type is “Dial On Demand”, the
connection will be initiated only when needed.
High Water Mark and
High Water Time
BOD stands for bandwidth-on-demand for Multiple-Link PPP
(ML-PPP or MP). High Water Mark/ High Water Time/
Low Water Mark/Low Water Time parameters are applied
when you set the Link Type to Dialup BOD. The ISDN
usually uses one B channel to access the Internet or remote
network when you choose the Dialup BOD link type. The
router will use the parameters here to decide on when you
activate/drop the additional B channel. Note that cps
(characters-per-second) measures the total link utilization.
These parameters specify the situation in which the second
channel will be activated. With the first connected channel, if
its utilization exceeds the High Water Mark and such a
channel is being used over the High Water Time, the
additional channel will be activated. Thus, the total link speed
will be 128kbps (two B channels).
Low Water Mark and Low These parameters specify the situation in which the second
channel will be dropped. In terms of the two B channels, if
Water Time
their utilization is under the Low Water Mark and these two
channels are being used over the High Water Time, the
additional channel will be dropped. As a result, the total link
speed will be 64kbps (one B channel).
Note: If you are not sure whether your ISP can support BOD and/or ML-PPP’s
features, please seek assistance from your ISP, local dealers or our website:
support@draytek.com.
3.3 Call Schedule Setup
The Vigor router has a built-in real time clock which can update itself manually or
automatically by means of Network Time Protocols (NTP). As a result, you can not only
schedule the router to dialup to the Internet at a specified time, but also restrict Internet access
to certain hours so that users can connect to the Internet only during certain hours, say,
business hours. The schedule is also applicable to other functions.
You have to set your time before set schedule. In the System Management group, select
Time and Date to open the time setup page, press Inquire Time button to set the Vigor
router’s clock to current time of your PC. The clock will reset once if you power down or reset
the router. There is another way to set up time. You can inquiry an NTP server (a time server)
on the Internet to synchronize the router’s clock. This method can only be applied when the
WAN connection has been built up.

1.
Make sure the PPPoE connection and Call Schedule Setup is working properly.
2.
Configure the PPPoE always on from 9:00 to 18:00 for whole week.
3.
Configure the Force Down from 18:00 to next day 9:00 for whole week.
Assign these two profiles to the PPPoE Internet access profile. Now, the PPPoE Internet
connection will follow the schedule order to perform Force On or Force Down action
according to the time plan that has been pre-defined in the schedule profiles.
3.4 NAT Setup
Usually, the router serves as an NAT (Network Address Translation) router. NAT is a
mechanism that one or more private IP addresses can be mapped into a single public one.
Public IP address is usually assigned by your ISP, for which you may get charged. Private IP
addresses are recognized only among internal hosts.
When the outgoing packets destined to some public server on the Internet reach the NAT
router, the router will change its source address into the public IP address of the router, select
the available public port, and then forward it. At the same time, the router shall list an entry in
a table to memorize this address/port-mapping relationship. When the public server response,
the incoming traffic, of course, is destined to the router’s public IP address and the router will
do the inversion based on its table. Therefore, the internal host can communicate with external
host smoothly.
The benefit of the NAT includes:
58
z
Save cost on applying public IP address and apply efficient usage of IP address.
NAT allows the internal IP addresses of local hosts to be translated into one public IP
address, thus you can have only one IP address on behalf of the entire internal hosts.
z
Enhance security of the internal network by obscuring the IP address. There are
many attacks aiming victims based on the IP address. Since the attacker cannot be aware
of any private IP addresses, the NAT function can protect the internal network.
Vigor2900 Series User’s Guide
On NAT page, you will see the private IP address defined in RFC-1918. Usually we
use the 192.168.1.0/24 subnet for the router. As stated before, the NAT facility can
map one or more IP addresses and/or service ports into different specified services.
In other words, the NAT function can be achieved by using port mapping methods.
Click NAT Setup on the Advanced Setup page. The setting items for NAT will be shown as
below.
3.4.1 Configure Port Redirection Table
Port Redirection is usually set up for server related service inside the local network (LAN),
such as web servers, FTP servers, E-mail servers etc. Most of the case, you need a public IP
address for each server and this public IP address/domain name are recognized by all users.
Since the server is actually located inside the LAN, the network well protected by NAT of the
router, and identified by its private IP address/port, the goal of Port Redirection function is to
forward all access request with public IP address from external users to the mapping private IP
address/port of the server.
The port redirection can only apply to incoming traffic.
To use this function, please go to NAT page and choose Port Redirection web page. The
Port Redirection Table provides 10 port-mapping entries for the internal hosts.
Vigor2900 Series User’s Guide
59
Service Name
Enter the description of the specific network service.
Protocol
Select the transport layer protocol (TCP or UDP).
Public Port
Specify which port can be redirected to the specified Private IP and
Port of the internal host.
Private IP
Specify the private IP address of the internal host providing the
service.
Private Port
Specify the private port number of the service offered by the internal
host.
Active
Check this box to activate the port-mapping entry you have defined.
Note that the router has its own built-in services (servers) such as Telnet, HTTP and FTP etc.
Since the common port numbers of these services (servers) are all the same, you may need to
reset the router in order to avoid confliction.
For example, the built-in web configurator in the router is with default port 80, which may
conflict with the web server in the local network, http://192.168.1.13:80. Therefore, you need
to change the router’s http port to any one other than the default port 80 to avoid conflict,

3.4.2 DMZ Host Setup
As mentioned above, Port Redirection can redirect incoming TCP/UDP or other traffic on
particular ports to the specific private IP address/port of host in the LAN. However, other IP
protocols, for example Protocols 50 (ESP) and 51 (AH), do not travel on a fixed port. Vigor
router provides a facility DMZ Host that maps ALL unsolicited data on any protocol to a
single host in the LAN. Regular web surfing and other such Internet activities from other
clients will continue to work without inappropriate interruption. DMZ Host allows a defined
internal user to be totally exposed to the Internet, which usually helps some special
applications such as Netmeeting or Internet Games etc.
The inherent security properties of NAT are somewhat bypassed if you set up DMZ
host. We suggest you to add additional filter rules or a secondary firewall.

with the neighboring routers via the 1st subnet (192.168.1.0/24). The second
68
Vigor2900 Series User’s Guide
is that those hosts on the internal private subnets (ex. 192.168.10.0/24) can
access the Internet via the router, and continuously exchange of IP routing
information with different subnets.

3.7 IP Filter/Firewall Setup
3.7.1 Basics for Firewall
While the broadband users demand more bandwidth for multimedia, interactive applications,
or distance learning, security has been always the most concerned. The firewall of the Vigor
router helps to protect your local network against attack from unauthorized outsiders. It also
restricts users in the local network from accessing the Internet. Furthermore, it can filter out
specific packets that trigger the router to build an unwanted outgoing connection.
The most basic security concept is to set user name and password while you install your router.
The administrator login will prevent unauthorized access to the router configuration from your
router.
Firewall Facilities
The users on the LAN are provided with secured protection by the following firewall facilities:
z
User-configurable IP filter (Call Filter/ Data Filter).
z
Stateful Packet Inspection (SPI): tracks packets and denies unsolicited incoming data
z
Selectable Denial of Service (DoS) /Distributed DoS (DDoS) attacks protection
z
URL Content Filter
IP Filters
Depending on whether there is an existing Internet connection, or in other words “the WAN
link status is up or down”, the IP filter architecture categorizes traffic into two: Call Filter and
Data Filter.
z
72
Call Filter - When there is no existing Internet connection, Call Filter is applied to all
traffic, all of which should be outgoing. It will check packets according to the filter rules.
If legal, the packet will pass. Then the router shall “initiate a call” to build the Internet
connection and send the packet to Internet.
Vigor2900 Series User’s Guide
z
Data Filter - When there is an existing Internet connection, Data Filter is applied to
incoming and outgoing traffic. It will check packets according to the filter rules. If legal,
the packet will pass the router.
The following illustrations are flow charts explaining how router will treat incoming traffic
and outgoing traffic respectively.
Stateful Packet Inspection (SPI)
Stateful inspection is a firewall architecture that works at the network layer. Unlike legacy
static packet filtering, which examines a packet based on the information in its header, stateful
inspection builds up a state machine to track each connection traversing all interfaces of the
firewall and makes sure they are valid. The stateful firewall of Vigor router not just examine
the header information also monitor the state of the connection.
Instant Messenger (IM) and Peer-to-Peer (P2P) Application Blocking
As the popularity of all kinds of instant messenger application arises, communication cannot
become much easier. Nevertheless, while some industry may leverage this as a great tool to
connect with their customers, some industry may take reserve attitude in order to reduce
employee misusage during office hour or prevent unknown security leak. It is similar situation
for corporation towards peer-to-peer applications since file-sharing can be convenient but
insecure at the same time. To address these needs, we provide IM and P2P blocking
functionality.
Vigor2900 Series User’s Guide
73
Denial of Service (DoS) Defense
The DoS Defense functionality helps you to detect and mitigate the DoS attack. The attacks
are usually categorized into two types, the flooding-type attacks and the vulnerability attacks.
The flooding-type attacks will attempt to exhaust all your system's resource while the
vulnerability attacks will try to paralyze the system by offending the vulnerabilities of the
protocol or operation system.
The DoS Defense function enables the Vigor router to inspect every packet based on the attack
signature database. Any malicious packet that might duplicate itself to paralyze the host in the
secure LAN will be strictly blocked and a Syslog message will be sent as warning, if you set up
Syslog server.
Also the Vigor router monitors the traffic. Any abnormal traffic flow violating the pre-defined
parameter, such as the number of thresholds, is identified as an attack and the Vigor router will
activate its defense mechanism to mitigate in a real-time manner.
The below shows the attack types that DoS/DDoS defense function can detect:
1. SYN flood attack
2. UDP flood attack
3. ICMP flood attack
4. TCP Flag scan
5. Trace route
6. IP options
7. Unknown protocol
8. Land attack
9. Smurf attack
10. SYN fragment
11. ICMP fragment
12. Tear drop attack
13. Fraggle attack
14. Ping of Death attack
15. TCP/UDP port scan
URL Content Filter
To provide an appropriate cyberspace to users, Vigor router equips with URL Content Filter
not only to limit illegal traffic from/to the inappropriate web sites but also prohibit other web
feature where malicious code may conceal.
Once a user type in or click on an URL with objectionable keywords, URL keyword blocking
facility will decline the HTTP request to that web page thus can limit user’s access to the
website. You may imagine URL Content Filter as a well-trained convenience-store clerk who
won’t sell adult magazines to teenagers. At office, URL Content Filter can also provide a
job-related only environment hence to increase the employee work efficiency. How can URL
Content Filter work better than traditional firewall in the field of filtering? Because it checks
the URL strings or some of HTTP data hiding in the payload of TCP packets while legacy
firewall inspects packets based on the fields of TCP/IP headers only.
On the other hand, Vigor router can prevent user from accidentally downloading malicious
codes from web pages. It’s very common that malicious codes conceal in the executable objects,
such as ActiveX, Java Applet, compressed files, and other executable files. Once downloading
these types of files from websites, you may risk bringing threat to your system. For example, an
ActiveX control object is usually used for providing interactive web feature. If malicious code
hides inside, it may occupy user’s system.
74
Vigor2900 Series User’s Guide
Web Content Filter (for V models only)
We all know that the content on the Internet just like other types of media may be
inappropriate sometimes. As a responsible parent or employer, you should protect those in your
trust against the hazards. With Web filtering service of the Vigor router, you can protect your
business from common primary threats, such as productivity, legal liability, network and
security threats. For parents, you can protect your children from viewing adult websites or chat
rooms.
Once you have activated your Web Filtering service in Vigor router and chosen the categories of
website you wish to restrict, each URL address requested (e.g.www.bbc.co.uk) will be checked
against our server database, powered by SurfControl. The database covering over 70 languages
and 200 countries, over 1 billion Web pages divided into 40 easy-to-understand categories. This
database is updated as frequent as daily by a global team of Internet researchers. The server will
look up the URL and return a category to your router. Your Vigor router will then decide
whether to allow access to this site according to the categories you have selected. Please note
that this action will not introduce any delay in your Web surfing because each of multiple load
balanced database servers can handle millions of requests for categorization.
Choose IP Filter/Firewall Setup on the Advanced Setup group. Below shows the menu
items for Firewall.

packets in the same session as the matched packet is applied to Data
Filer, they will be checked against the rules in State table first. If
matched, they can pass immediately without having to check any
rule in Data Filter. Only ICMP, TCP and UDP protocols can be
added to State table.

Enable Dos Defense
Check the box to activate the DoS Defense Functionality.
Enable SYN flood
defense
Check the box to activate the SYN flood defense function. Once
detecting the Threshold of the TCP SYN packets has exceeded the
defined value, the Vigor router will start to discard the subsequent
TCP SYN packets for a period defined in Timeout. The goal for
this is prevent the TCP SYN packets’ attempt to exhaust the
limited-resource of Vigor router. By default, the threshold and
timeout values are set to 50 packets per second and 10 seconds,
respectively.
Enable UDP flood
defense
Check the box to activate the UDP flood defense function. Once
detecting the Threshold of the UDP packets has exceeded the
defined value, the Vigor router will start to discard the subsequent
UDP packets for a period defined in Timeout. The default setting
for threshold and timeout are 150 packets per second and 10
seconds, respectively.
Enable ICMP flood
defense
Check the box to activate the ICMP flood defense function. Similar
to the UDP flood defense function, once if the Threshold of ICMP
packets has exceeded the defined value, the router will discard the
ICMP echo requests coming from the Internet. The default setting
for threshold and timeout are 50 packets per second and 10 seconds,
respectively.
Enable PortScan
detection
Port Scan attacks the Vigor router by sending lots of packets to
many ports in an attempt to find ignorant services would respond.
Check the box to activate the Port Scan detection. Whenever
detecting this malicious exploration behavior by monitoring the
port-scanning Threshold rate, the Vigor router will send out a
warning. By default, the Vigor router sets the threshold as 150
packets per second.
Block IP options
Check the box to activate the Block IP options function. The Vigor
router will ignore any IP packets with IP option field in the datagram
Vigor2900 Series User’s Guide
header. The reason for limitation is IP option appears to be a
vulnerability of the security for the LAN because it will carry
significant information, such as security, TCC (closed user group)
parameters, a series of Internet addresses, routing messages...etc. An
eavesdropper outside might learn the details of your private
networks.
Block Land
Check the box to enforce the Vigor router to defense the Land
attacks. The Land attack combines the SYN attack technology with
IP spoofing. A Land attack occurs when an attacker sends spoofed
SYN packets with the identical source and destination addresses, as
well as the port number to victims.
Block Smurf
Check the box to activate the Block Smurf function. The Vigor router
will ignore any broadcasting ICMP echo request.
Block trace router
Check the box to enforce the Vigor router not to forward any trace
route packets.
Block SYN fragment
Check the box to activate the Block SYN fragment function. The
Vigor router will drop any packets having SYN flag and more
fragment bit set.
Block Fraggle Attack
Check the box to activate the Block fraggle Attack function. Any
broadcast UDP packets received from the Internet is blocked.
Activating the DoS/DDoS defense functionality might block some
legal packets. For example, when you activate the fraggle attack
defense, all broadcast UDP packets coming from the Internet are
blocked. Therefore, the RIP packets from the Internet might be
dropped.
Block TCP flag scan
Check the box to activate the Block TCP flag scan function. Any TCP
packet with anomaly flag setting is dropped. Those scanning activities
include no flag scan, FIN without ACK scan, SYN FINscan, Xmas
scan and full Xmas scan.
Block Tear Drop
Check the box to activate the Block Tear Drop function. Many
machines may crash when receiving ICMP datagrams (packets) that
exceed the maximum length. To avoid this type of attack, the Vigor
router is designed to be capable of discarding any fragmented ICMP
packets with a length greater than 1024 octets.
Block Ping of Death
Check the box to activate the Block Ping of Death function. This
attack involves the perpetrator sending overlapping packets to the
target hosts so that those target hosts will hang once they
re-construct the packets. The Vigor routers will block any packets
realizing this attacking activity.
Block ICMP Fragment Check the box to activate the Block ICMP fragment function. Any
ICMP packets with more fragment bit set are dropped.
Block Land
Check the box to enforce the Vigor router to defense the Land
attacks. The Land attack combines the SYN attack technology with
IP spoofing. A Land attack occurs when an attacker sends spoofed
SYN packets with the identical source and destination addresses, as
well as the port number to victims.
Block Unknown
Protocol
Check the box to activate the Block Unknown Protocol function.
Individual IP packet has a protocol field in the datagram header to
indicate the protocol type running over the upper layer. However,
Vigor2900 Series User’s Guide
83
the protocol types greater than 100 are reserved and undefined at
this time. Therefore, the router should have ability to detect and
reject this kind of packets.
Warning Messages
We provide Syslog function for user to retrieve message from Vigor
router. The user, as a Syslog Server, shall receive the report sending
from Vigor router which is a Syslog Client.
All the warning messages related to DoS defense will be sent to user
and user can review it through Syslog daemon. Look for the keyword
DoS in the message, followed by a name to indicate what kind of
attacks is detected.
3.7.5 URL Content Filter
Based on the list of user defined keywords, the URL Content Filter facility in Vigor router
inspects the URL string in every outgoing HTTP request. No matter the URL string is found
full or partial matched with a keyword, the Vigor router will block the associated HTTP
connection.
For example, if you add key words such as “sex”, Vigor router will limit web access to web
sites or web pages such as “www.sex.com”, ”www.backdoor.net/images/sex/p_386.html”. Or
you may simply specify the full or partial URL such as “www.sex.com” or “sex.com”.
Also the Vigor router will discard any request that tries to retrieve the malicious code.

within a frame are separated by space, comma, or semicolon. In
addition, the maximal length of each frame is 32-character long.
After specifying keywords, the Vigor router will decline the
connection request to the website whose URL string matched to any
user-defined keyword. It should be noticed that the more simplified
the blocking keyword list, the more efficiently the Vigor router
perform.

3.8 VPN and Remote Access Setup
A Virtual Private Network (VPN) is the extension of a private network that encompasses links
across shared or public networks like the Internet. In short, by VPN technology, you can send
data between two computers across a shared or public network in a manner that emulates the
properties of a point-to-point private link.
Choose VPN and Remote Access Setup on the Advanced Setup group, you can see the
following page.
3.8.1 Remote Access Control Setup
Enable the necessary VPN service as you need. If you intend to run a VPN server inside your
LAN, you should disable the VPN service of Vigor Router to allow VPN tunnel pass through,
as well as the appropriate NAT settings, such as DMZ or open port.
3.8.2 PPP General Setup
This submenu only applies to PPP-related VPN connections, such as PPTP, L2TP, L2TP over
IPSec.
90
Vigor2900 Series User’s Guide
Dial-In PPP
Authentication
PAP Only - Select this option to force the router to
authenticate dial-in users with the PAP protocol.
PAP or CHAP - Selecting this option means the router will
attempt to authenticate dial-in users with the CHAP protocol
first. If the dial-in user does not support this protocol, it will
fall back to use the PAP protocol for authentication.
Dial-In PPP Encryption
( MPPE)
This option represents that the MPPE encryption method will
be optionally employed in the router for the remote dial-in
user. If the remote dial-in user does not support the MPPE
encryption algorithm, the router will transmit “no MPPE
encrypted packets”. Otherwise, the MPPE encryption scheme
will be used to encrypt the data.
Require MPPE (40/128bits) - Selecting this option will force
the router to encrypt packets by using the MPPE encryption
algorithm. In addition, the remote dial-in user will use 40-bit
to perform encryption prior to using 128-bit for encryption.
In other words, if 1280-bit MPPE encryption method is not
available, then 40-bit encryption scheme will be applied to
encrypt the data.
Maximum MPPE - This option indicates that the router will
use the MPPE encryption scheme with maximum bits (128
bits) to encrypt the data.
Mutual Authentication
(PAP)
The Mutual Authentication function is mainly used to
communicate with other routers or clients who need
bi-directional authentication in order to provide stronger
security, for example, Cisco routers. So you should enable
this function when your peer router requires mutual
authentication. You should further specify the User Name
and Password of the mutual authentication peer.
Start IP Address
Enter a start IP address for the dial-in PPP connection. You
should choose an IP address from the local private network.
For example, if the local private network is
192.168.1.0/255.255.255.0, you could choose 192.168.1.200 as
the Start IP Address. But, you have to notice that the first two
IP addresses of 192.168.1.200 and 192.168.1.201 are reserved
for ISDN remote dial-in user.

3.8.3 VPN IKE/IPSec General Setup
In IPSec General Setup, there are two major parts of configuration.
There are two phases of IPSec.
¾
Phase 1: negotiation of IKE parameters including encryption, hash, Diffie-Hellman
parameter values, and lifetime to protect the following IKE exchange, authentication of
both peers using either a Pre-Shared Key or Digital Signature (x.509). The peer that
starts the negotiation proposes all its policies to the remote peer and then remote peer
tries to find a highest-priority match with its policies. Eventually to set up a secure tunnel
for IKE Phase 2.
¾
Phase 2: negotiation IPSec security methods including Authentication Header (AH) or
Encapsulating Security Payload (ESP) for the following IKE exchange and mutual
examination of the secure tunnel establishment.
There are two encapsulation methods used in IPSec, Transport and Tunnel. The Transport
mode will add the AH/ESP payload and use original IP header to encapsulate the data payload
only. It can just apply to local packet, e.g., L2TP over IPSec. The Tunnel mode will not only
add the AH/ESP payload but also use a new IP header (Tunneled IP header) to encapsulate the
whole original IP packet.
Authentication Header (AH) provides data authentication and integrity for IP packets passed
between VPN peers. This is achieved by a keyed one-way hash function to the packet to create
a message digest. This digest will be put in the AH and transmitted along with packets. On the
receiving side, the peer will perform the same one-way hash on the packet and compare the
value with the one in the AH it receives.
Encapsulating Security Payload (ESP) is a security protocol that provides data confidentiality
and protection with optional authentication and replay detection service.
IKE Authentication Method This usually applies to those are remote dial-in user or node
(LAN-to-LAN) which uses dynamic IP address and
IPSec-related VPN connections such as L2TP over IPSec and
IPSec tunnel.
Pre-Shared Key -Currently only support Pre-Shared Key
authentication. Specify a key for IKE authentication.
Re-type Pre-Shared Key -Confirm the pre-shared key.
IPSec Security Method
92
Medium - Authentication Header (AH) means data will be
authenticated, but not be encrypted. By default, this option is
active.
High - Encapsulating Security Payload (ESP) means payload
Vigor2900 Series User’s Guide
(data) will be encrypted and authenticated. You may select
encryption algorithm from Data Encryption Standard (DES),
Triple DES (3DES), and AES.
3.8.4 Remote User Profile Setup (Teleworker)
You can manage remote access by maintaining a table of remote user profile, so that users can
be authenticated to dial-in or build the VPN connection. You may set parameters including
specified connection peer ID, connection type (VPN including PPTP, IPSec Tunnel, and L2TP
by itself or over IPSec) and corresponding security methods, etc.

Enable PING to keep alive This function is to help the router to determine the status of
IPSec VPN connection, especially useful in the case of
abnormal VPN IPSec tunnel disruption. For details, please refer
to the note below. Check to enable the transmission of PING
packets to a specified IP address.
PING to the IP
Enter the IP address of the remote host that located at the
other-end of the VPN tunnel.
Enable PING to Keep Alive is used to handle abnormal
IPSec VPN connection disruption. It will help to provide the
state of a VPN connection for router’s judgment of redial.
Normally, if any one of VPN peers wants to disconnect the
connection, it should follow a serial of packet exchange
procedure to inform each other. However, if the remote peer
disconnect without notice, Vigor router will by no where to
know this situation. To resolve this dilemma, by continuously
sending PING packets to the remote host, the Vigor router
can know the true existence of this VPN connection and react
accordingly. This is independent of DPD (dead peer
detection).

3.9 UPNP Service Setup
The UPnP (Universal Plug and Play) protocol is supported to bring to network connected
devices the ease of installation and configuration which is already available for directly
connected PC peripherals with the existing Windows 'Plug and Play' system. For NAT routers,
the major feature of UPnP on the router is “NAT Traversal”. This enables applications inside
the firewall to automatically open the ports that they need to pass through a router. It is more
reliable than requiring a router to work out by itself which ports need to be opened. Further,
the user does not have to manually set up port mappings or a DMZ. UPnP is available on
Windows XP and the router provides the associated support for MSN Messenger to allow full
use of the voice, video and messaging features.
Enable UPNP Service
Accordingly, you can enable either the Connection Control
Service or Connection Status Service.
After setting Enable UPNP Service setting, an icon of IP Broadband Connection on Router
on Windows XP/Network Connections will appear. The connection status and control status
will be able to be activated. The NAT Traversal of UPnP enables the multimedia features of
102
Vigor2900 Series User’s Guide
your applications to operate. This has to manually set up port mappings or use other similar
methods. The screenshots below show examples of this facility.
The UPnP facility on the router enables UPnP aware applications such as MSN Messenger to
discover what are behind a NAT router. The application will also learn the external IP address
and configure port mappings on the router. Subsequently, such a facility forwards packets from
the external ports of the router to the internal ports used by the application.
The reminder as regards concern about Firewall and UPnP Can't work with Firewall Software
Enabling firewall applications on your PC may cause the UPnP function not
working properly. This is because these applications will block the accessing
ability of some network ports.
Security Considerations
Activating the UPnP function on your network may incur some security threats.
You should consider carefully these risks before activating the UPnP function.
Vigor2900 Series User’s Guide
103
¾ Some Microsoft operating systems have found out the UPnP weaknesses and
hence you need to ensure that you have applied the latest service packs and
patches.
¾ Non-privileged users can control some router functions, including removing
and adding port mappings.
The UPnP function dynamically adds port mappings on behalf of some
UPnP-aware applications. When the applications terminate abnormally, these
mappings may not be removed.
3.10 VoIP Setup
Note: This setting is available for V model series.
Voice over IP network (VoIP) enables you to use your broadband Internet connection to make
toll quality voice calls over the Internet.
There are many different call signaling protocols, methods by which VoIP devices can talk to
each other. The most popular protocols are SIP, MGCP, Megaco and H.323. These protocols
are not all compatible with each other (except via a soft-switch server).
The Vigor V models support the SIP protocol as this is an ideal and convenient deployment
for the ITSP (Internet Telephony Service Provider) and softphone and is widely supported.
SIP is an end-to-end, signaling protocol that establishes user presence and mobility in VoIP
structure. Every one who wants to talk using his/her SIP Uniform Resource Identifier, “SIP
Address”. The standard format of SIP URI is
sip: user:password @ host: port
Some fields may be optional in different use. In general, "host” refers to a domain. The
“userinfo” includes the user field, the password field and the @ sign following them. This is
very similar to a URL so some may call it “SIP URL”. SIP supports peer-to-peer direct calling
and also calling via a SIP proxy server (a role similar to the gatekeeper in H.323 networks),
while the MGCP protocol uses client-server architecture, the calling scenario being very
similar to the current PSTN network.
After a call is setup, the voice streams transmit via RTP (Real-Time Transport Protocol).
Different codecs (methods to compress and encode the voice) can be embedded into RTP
packets. Vigor V models provide various codecs, including G.711 A/µ-law, G.723, G.726 and
G.729 A & B. Each codec uses a different bandwidth and hence provides different levels of
voice quality. The more bandwidth a codec uses the better the voice quality, however the
codec used must be appropriate for your Internet bandwidth.
Usually there will be two types of calling scenario, as illustrated below:
z
Calling via SIP Servers
First, the Vigor V models of yours will have to register to a SIP Registrar by sending
registration messages to validate. Then, both parties’ SIP proxies will forward the
sequence of messages to caller to establish the session.
If you both register to the same SIP Registrar, then it will be illustrated as below:
104
Vigor2900 Series User’s Guide
The major benefit of this mode is that you don’t have to memorize your friend’s IP
address, which might change very frequently if it’s dynamic. Instead of that, you will
only have to using dial plan or directly dial your friend’s account name if you are with
the same SIP Registrar. Please refer to the Example 1 and 2 in the Calling Scenario.
z
Peer-to-Peer
Before calling, you have to know your friend’s IP Address. The Vigor VoIP Routers will
build connection between each other. Please refer to the Example 3 in the Calling
Scenario.
Our Vigor V models firstly apply efficient codecs designed to make the best use of
available bandwidth, but Vigor V models also equip with automatic QoS assurance.
QoS Assurance assists to assign high priority to voice traffic via Internet. You will
always have the required inbound and outbound bandwidth that is prioritized exclusively
for Voice traffic over Internet but you just get your data a little slower and it is tolerable
for data traffic.

3.10.1 DialPlan Setup
In this section, you can set your VoIP contacts in the “phonebook” we called DialPlan - help
you to make calls quickly and easily by using “speed-dial” Phone Number. There are total 60
index entries in the DialPlan for you to store all your friends and family members’ SIP
addresses.
Click any index number to display the dial plan setup page.
Enable
Click this to enable this entry.
Phone Number
The speed-dial number of this index. This can be any number
you choose, using digits 0-9 and * .
Display Name
The Caller-ID that you want to be displayed on your friend’s
screen. This let your friend can easily know who’s calling
without memorizing lots of SIP URL Address.
SIP URL
Enter your friend’s SIP Address.
Example 1:
If Tom gives you a SIP URL as sip:1112@fwd.pulver.com then you can input the number
just as the previous figure, except you can change any number in the Phone Number field.
Example 2:
If Kevin gives you an IP address 203.69.175.16 only, then you can use keypad on the phone to
dial directly as #203*69*175*16# to Kevin without setup any information on your DialPlan.

3.10.2 SIP Related Functions Setup
In this section, you set up your own SIP settings. When you apply for an account, your SIP
service provider will give you an Account Name or user name, SIP Registrar, Proxy, and
Domain name. (The last three might be the same in some case). Then you can tell your folks
your SIP Address as in Account Name@ Domain name
As Vigor VoIP Router is turned on, it will first register with Registrar using
accountname@Domain/Realm. After that, your call will be bypassed by SIP Proxy to the
destination using AccountName@Domain/Realm as identity.
SIP Port
The port number is used to send/receive SIP message for
building a session. While the default value is 5060, you can
change it to other number. However, this situation needs other
party to change simultaneously to the same number.
By the time you can type:port number after the domain name to
specify that port as the destination of data transmission (e.g.,
nat.draytel.org:5065)
Domain
You can enter domain name or IP address of SIP Registrar
server. For example, iptel.org or 195.37.77.101 is identical. You
have to apply an account of SIP Registrar server before you can
use it. However, it is not necessary to use sip registrar server
function in order to use VoIP function.
Proxy
You can enter IP address of SIP proxy server. For all SIP
messages destined the Domain defined above, Vigor router will
send to the Proxy and the Proxy will forward it.
Outbound Proxy
You can enter IP address of outbound SIP proxy server. For all
SIP messages, Vigor router will send to the Outbound Proxy
and the will Outbound Proxy forward it.
Register via

Adjust the volume of microphone and speaker by entering
number from 1- 10. The larger of the number, the louder the
volume is.
Default Codec
There are five different CODECs you can choose as your prefer
CODEC that you wish to use. However, the real CODEC be
used was negotiate with peer party before session was
established. The default CODEC is G.729A/B; it occupied less
bandwidth while still have good voice quality. It is better for
you to have at least 256Kbps upstream if you would like to use
G.711.
NOTE: If your upstream speed only supports
64Kbps, do not use G.711 CODEC.

3.12 QoS Control Setup
Deploying QoS (Quality of Service) management to guarantee that all applications receive the
service levels required and sufficient bandwidth to meet performance expectations is indeed
one important aspect of modern enterprise network.
One reason for QoS is that numerous TCP-based applications tend to continually increase their
transmission rate and consume all available bandwidth, which is called TCP slow start. If
other applications are not protected by QoS, it will detract much from their performance in the
overcrowded network. This is especially essential to those are low tolerant of loss, delay or
jitter (delay variation), such as voice over IP, videoconferencing, streaming video or data.
Another reason is due to congestions at network intersections where speeds of interconnected
circuits mismatch or traffic aggregates, packets will queue up and traffic can be throttled back
to a lower speed. If there’s no defined priority to specify which packets should be discarded
(or in another term “dropped”) from an overflowing queue, packets of sensitive applications
mentioned above might be the ones to drop off. How this will affect application performance?
There are two components within Primary configuration of QoS deployment:
z
Classification: Identifying low-latency or crucial applications and marking them for
high-priority service level enforcement throughout the network.
z
Scheduling: Based on classification of service level to assign packets to queues and
associated service types
The basic QoS implementation in Vigor routers is to classify and schedule packets based on
the service type information in the IP header. For instance, to ensure the connection with the
headquarter, a teleworker may enforce an index of QoS Control to reserve bandwidth for
HTTPS connection while using lots of application at the same time.
One more larger-scale implementation of QoS network is to apply DSCP (Differentiated
Service Code Point) and IP Precedence disciplines at Layer 3. Compared with legacy IP
Precedence that uses Type of Service (ToS) field in the IP header to define 8 service classes,
DSCP is a successor creating 64 classes possible with backward IP Precedence compatibility.
In a QoS-enabled network, or Differentiated Service (DiffServ or DS) framework, a DS
domain owner should sign a Service License Agreement (SLA) with other DS domain owners
to define the service level provided toward traffic from different domains. Then each DS node
in these domains will perform the priority treatment. This is called per-hop-behavior (PHB).
The definition of PHB includes Expedited Forwarding (EF), Assured Forwarding (AF), and
Best Effort (BE). AF defines the four classes of delivery (or forwarding) classes and three
levels of drop precedence in each class.
Vigor2900 Series User’s Guide
115
Vigor routers as edge routers of DS domain shall check the marked DSCP value in the IP
header of bypassing traffic, thus to allocate certain amount of resource execute appropriate
policing, classification or scheduling. The core routers in the backbone will do the same
checking before executing treatments in order to ensure service-level consistency throughout
the whole QoS-enabled network.
However, each node may take different attitude toward packets with high priority marking
since it may bind with the business deal of SLA among different DS domain owners. It’s not
easy to achieve deterministic and consistent high-priority QoS traffic throughout the whole
network with merely Vigor router’s effort.
The following QoS policies will be defined in the form of ratio of upstream/downstream speed.
We will also provide application QoS requirement as reference to help you accomplish this
task. The setting values will vary depending on the network condition.
Click on QoS Control on the Advanced Setup group. The following screen will appear.
WAN Inbound Bandwidth Type the inbound bandwidth for WAN interface.
WAN Outbound Bandwidth Type the outbound bandwidth for WAN interface.

5.4 LAN – Created by Using NAT
An example of default setting and the corresponding deployment are shown below. The
default Vigor router private IP address/Subnet Mask is 192.168.1.1/255.255.255.0. The built-in
DHCP server is enabled so it assigns every local NATed host an IP address of 192.168.1.x
starting from 192.168.1.10.
Vigor2900 Series User’s Guide
151
You can just set the settings wrapped inside the red rectangles to fit the request of NAT usage.
To use another DHCP server in the network rather than the built-in one of Vigor Router, you
