Preface
The Vigor2100 Series router includes Vigor2100G ,Vigor2100V and Vigor2100VG models.
To secure your network, the Vigor2100 series provides an advanced firewall with advanced
features, such as NAT with multi VPN pass-through, Stateful Packet Inspection (SPI) to offer
network reliability by detecting and prohibiting malicious penetrating packets or DoS attacks,
user-configurable web filtering for parental control against network abuse etc.
For G series model, it is embedded with an 802.11g compliant wireless module which
provides wireless LAN access with data rate as much as (up to 54Mbps for Vigor2100G/VG).
For V series model, with VoIP phone ports, it provides an Internet access solution for your
LAN via shared web surfing and countless value-added features, such as Firewall, Security
and VoIP. These are all in a reliable one-box solution. The V series model has a “Line” port
on the rear panel for connecting to a PSTN (regular analogue) line. The Loop Through option
can be used to set an alternate telephone number for your contact on the PSTN, which the
Vigor2100V series will dial instead of the SIP account if you lose ADSL access or power to
the Vigor2100V series. Hence, the PSTN line can act as a lifeline (backup mechanism) for
VoIP calls. The lifeline mechanism is activated automatically but can also be manually
configured.

3.1 Internet Access
3.1.1 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 of the host PCs can share a common Internet connection.
Get Your Public IP Address from ISP
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.
Below shows the menu items of Internet Access.
Vigor2100 Series User’s Guide
19
3.1.2 PPPoE
As a CPE device, Vigor router encapsulates the PPP session based for transport across the

3.2 LAN
Local Area Network (LAN) is a group of subnets regulated and ruled by router. The design of
network structure is related to what type of public IP addresses coming from your ISP.
3.2.1 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
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.
Vigor2100 Series User’s Guide
25
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.
3.2.2 LAN TCP/IP and DHCP
This page provides you the general settings for LAN.
Click LAN to open the LAN settings page and choose LAN TCP/IP and DHCP.
26
IP Address
Type in private IP address for connecting to a local private network
(Default: 192.168.1.1).
Subnet Mask
Type in an address code that determines the size of the network.
(Default: 255.255.255.0/ 24).
Vigor2100 Series User’s Guide
DHCP Server
Configuration
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
DHCP server for your network.
If you want to use another DHCP server in the network other than
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.
Enable Relay Agent – 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.
Vigor2100 Series User’s Guide
27
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 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.
3.3 NAT
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:
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.
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.
Below shows the menu items of NAT.
3.3.1 Port Redirection
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.
28
Vigor2100 Series User’s Guide
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.
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’s in order to avoid confliction.
Vigor2100 Series User’s Guide
29
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,
such as 8080. This can be set in the System Maintenance >>Management Setup. You then
will access the admin screen of by suffixing the IP address with 8080, e.g.,
http://192.168.1.1:8080 instead of port 80.
3.3.2 DMZ Host
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.
Note: 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.

3.4 Firewall
3.4.1 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.
Vigor2100 Series User’s Guide
33
If you did not set password during installation; you can go to System Maintenance to set up
your password.
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
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.
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.
34
Vigor2100 Series User’s Guide
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.
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.
Vigor2100 Series User’s Guide
35
The DoS Defense function enables the Vigor router to inspect every incoming 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 Filtering
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.
Web Filtering
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
36
Vigor2100 Series User’s Guide
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.
Below shows the menu items of Firewall.
3.4.2 General Setup

Logged Packet
Duplication
Logged packets may also be logged to another location via
Ethernet. If you want to duplicate logged packets from the router
to another network device, you must enter the other devices’ MAC
Address (HEX Format). Type “0” to disable the feature. The
feature will be helpful under Ethernet environments.
Vigor2100 Series User’s Guide
37
Some on-line games (for example: Half Life) will use lots of fragmented UDP packets to
transfer game data. Instinctively as a secure firewall, Vigor router will reject these fragmented
packets to prevent attack unless you enable Accept Incoming Fragmented UDP Packets. By
checking this box, you can play these kinds of on-line games. If security concern is in higher
priority, you cannot enable Accept Incoming Fragmented UDP Packets.

3.4.4 DoS Defense
As a sub-functionality of IP Filter/Firewall, there are 15 types of detect/ defense function in
the DoS Defense setup. The DoS Defense functionality is disabled for default.
Click Firewall and click DoS Defense to open the setup page.
42
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 from the Internet
has exceeded the defined value, the Vigor router will start to
randomly 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 from the Internet has
exceeded the defined value, the Vigor router will start to randomly
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 from Internet 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.
Vigor2100 Series User’s Guide
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
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.
Vigor2100 Series User’s Guide
43
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,
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. (Refer to System
Maintenance >> Syslog for detail information.)
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.
3.4.5 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.
44
Vigor2100 Series User’s Guide
Click Firewall and click URL Content Filter to open the setup page.
Enable URL Access
Control
Check the box to activate URL Access Control.
Keyword
The Vigor router provides 8 frames for users to define keywords and
each frame supports multiple keywords. The keyword could be a
noun, a partial noun, or a complete URL string. Multiple keywords
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

file function to prevent someone from downloading any compressed
file. The following list shows the types of compressed files that can
be blocked by the Vigor router.
zip, rar, .arj, .ace, .cab, .sit
Executable file - Check the box to reject any downloading behavior
of the executable file from the Internet.
.exe, .com, .scr, .pif, .bas, .bat, .inf, .reg
Cookie - Check the box to filter out the cookie transmission from
inside to outside world to protect the local user's privacy.
Proxy - Check the box to reject any proxy transmission. To control
efficiently the limited-bandwidth usage, it will be of great value to
provide the blocking mechanism that filters out the multimedia files
downloading from web pages. Accordingly, files with the following
extensions will be blocked by the Vigor router.
.mov
.mp3
.rm
.ra
.au
.wmv
.wav
.asf

duration from H1:M1 to H2:M2 in one day, where H1 and H2
indicate the hours. M1 and M2 represent the minutes.
Days of Week - Specify which days in one week should apply
the URL content filtering facility. The Vigor router supports
two exclusive options for users, i.e. everyday or some days in
one week. If you expect that the URL content filtering facility is
active for whole week, you should click the checkbox
“Everyday”. Otherwise, you should point clearly out the days
in one week. For example, if you want the URL content
filtering facility to work from Monday to Wednesday, then you
should click the appropriate checkboxes (Monday, Tuesday,

3.5 Applications
Below shows the menu items of Application.
3.5.1 Dynamic DNS
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.
Enable the Function and Add a Dynamic DNS Account

3.5.2 Call Schedule
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 System Maintenance>> Time Setup menu,
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.
You can set up to 15 schedules. Then you can apply them to your Internet Access.
To add a schedule, please click any index, say Index No. 1. Then adjust the detailed setting for
that one on the field just above Call Schedule Setup.

disconnected (Force Down).
Office
Hour:
(Force On)
Mon - Sun
9:00 am
to
6:00 pm
1.
Make sure the PPPoE connection and Time 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.
4.
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.
3.5.3 UPnP
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 provide the associated support for MSN Messenger to allow full
use of the voice, video and messaging features.
Vigor2100 Series User’s Guide
51
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
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.
52
Vigor2100 Series User’s Guide
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.
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.

3.6 VoIP
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:
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
Vigor2100 Series User’s Guide
55
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.
Below shows the menu items of VoIP.

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
AuthorizationUser@Domain/Realm. After that, your call will be bypassed by SIP Proxy to the
destination using AccountName@Domain/Realm as identity.
Note: Vigor VoIP router supports three SIP accounts from firmware version 2.5.9
and later.

3.7 Wireless LAN
Note: This function is used for G models only.
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.
3.7.1 Basic Concept
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 with other wired hosts via Vigor wireless router. The General
Settings will set up the information of this wireless network, including its SSID as
identification, located channel etc.
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 or 128-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.
Vigor2100 Series User’s Guide
69
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
Example 3

Vigor2100 Series User’s Guide
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.
Below shows the menu items of Wireless LAN.
3.7.2 General Settings
By clicking the General Settings, a new web page will appear so that you could configure the
SSID and the wireless channel. Please refer to the following figure for more information.
Enable Wireless LAN
Check the box to enable wireless function.
Mode
Select an appropriate wireless mode.
Mixed (11b+11g)-The router communicates with standard 802.11b
and standard 802.11g STAs simultaneously.
11g only-The router communicates with standard 802.11b STAs.
Vigor2100 Series User’s Guide
71
11b only-The router communicates with standard 802.11b STAs.
72
Scheduler (1-15)
Set the wireless LAN to work at certain time interval only. You may
choose up to 4 schedules out of the 15 schedules pre-defined in
Applications >> Schedule setup. The default setting of this filed is
blank and the function will always work.
SSID
Means the identification of the wireless LAN. SSID can be any text
numbers or various special characters. The default SSID is "default".
We suggest you to change it.
Channel
Means the channel of frequency of the wireless LAN. The default
channel is 6. You may switch channel if the selected channel is
under serious interference.
Hide SSID
Check it to prevent from wireless sniffing and make it harder for
unauthorized clients or STAs to join your 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
doing site survey.
Long Preamble
This option is to define the length of the sync field in an 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 device only support
long preamble. Check it to use Long Preamble if needed to
communicate with this kind of devices.
Vigor2100 Series User’s Guide
3.7.3 Security
By clicking the Security Settings, a new web page will appear so that you could configure the
settings of WEP and WPA.
Mode
Disable-Turn off the encryption mechanism. For the security of your
router, please select any one of the encryption mode here.
WEP-Accepts only WEP clients and the encryption key should be
entered in WEP Key.
WPA/PSK-Accepts only WPA clients and the encryption key
should be entered in PSK.
WPA2/PSK-Accepts only WPA2 clients and the encryption key
should be entered in PSK.
Mixed (WPA+ WPA2)/PSK - Accepts WPA and WPA2 clients
simultaneously and the encryption key should be entered in PSK.
WPA
The WPA encrypts each frame transmitted from the radio using the
key, which either PSK (Pre-Shared Key) entered manually in this
field below or automatically negotiated via 802.1x authentication.
Either 8~63 ASCII characters, such as 012345678(or 64
Hexadecimal digits leading by 0x, such as "0x321253abcde...").
WEP
For key length 64 bits - For 64 bits WEP key, either 5 ASCII
characters, such as 12345 (or 10 hexadecimal digitals leading by 0x,
such as 0x4142434445.)
Vigor2100 Series User’s Guide
73
For key length 128 bits - For 128 bits WEP key, either 13 ASCII
characters, such as ABCDEFGHIJKLM. (or 26 hexadecimal digits
leading by 0x, such as 0x4142434445464748494A4B4C4D)
All wireless devices must support the same WEP encryption bit size
and have the same key. Four keys can be entered here, but only one
key can be selected at a time. The keys can be entered in ASCII or
Hexadecimal. Check the key you wish to use.
3.7.4 Access Control
For additional security of wireless access, the Access Control facility allows you to restrict
the network access right by controlling the wireless LAN MAC address of client. Only the
valid MAC address that has been configured can access the wireless LAN interface. By

3.7.5 WDS
WDS means Wireless Distribution System. It is a protocol for connecting two access points
(AP) wirelessly. Usually, it can be used for the following application:
y
y
Provide bridge traffic between two LANs through the air.
Extend the coverage range of a WLAN.
To meet the above requirement, two WDS modes are implemented in Vigor router. One is
Bridge, the other is Repeater. Below shows the function of WDS-bridge interface:
The application for the WDS-Repeater mode is depicted as below:
Vigor2100 Series User’s Guide
75
The major difference between these two modes is that: while in Repeater mode, the packets
received from one peer AP can be repeated to another peer AP through WDS links. Yet in
Bridge mode, packets received from a WDS link will only be forwarded to local wired or
wireless hosts. In other words, only Repeater mode can do WDS-to-WDS packet forwarding.
In the following examples, hosts connected to Bridge 1 or 3 can communicate with hosts
connected to Bridge 2 through WDS links. However, hosts connected to Bridge 1 CANNOT
communicate with hosts connected to Bridge 3 through Bridge 2.
Click WDS from Wireless LAN menu. The following page will be shown.
