3.1.1 Basics of Internet Protocol (IP) Network
IP means Internet Protocol. Every device in an IP-based Network including modems, 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 modem 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
Vigor120 Series User’s Guide
15
What are Public IP Address and Private IP Address
As the modem 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 modem. The modem itself will also use the default private IP address: 192.168.1.1 to
communicate with the local hosts. Meanwhile, Vigor modem 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 modem 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
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 modem 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 for Internet Access.
3.1.2 PPPoE/PPPoA
PPPoA, included in RFC1483, can be operated in either Logical Link Control-Subnetwork
Access Protocol or VC-Mux mode. As a CPE device, Vigor modem encapsulates the PPP
session based for transport across the ADSL loop and your ISP’s Digital Subscriber Line
Access Multiplexer (SDLAM).
To choose PPPoE or PPPoA as the accessing protocol of the internet, please select
PPPoE/PPPoA from the Internet Access menu. The following web page will be shown.

3.2 LAN
Local Area Network (LAN) is a group of subnets regulated and ruled by modem. 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 modem is NAT. It creates a private subnet of your own.
As mentioned previously, the modem 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 modem 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
modem will serve for IP routing to help hosts in the public subnet to communicate with other
public hosts or servers outside. Therefore, the modem should be set as the gateway for public
hosts.
24
Vigor120 Series User’s Guide
What is Routing Information Protocol (RIP)
Vigor modem will exchange routing information with neighboring modems using the RIP to
accomplish IP routing. This allows users to change the information of the modem such as IP
address and the modems 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.
Vigor120 Series User’s Guide
25
4.2.2 General Setup
This page provides you the general settings for LAN.
Click LAN to open the LAN settings page and choose General Setup.
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)
DHCP Server
Configuration
DHCP stands for Dynamic Host Configuration Protocol. The
modem 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 modem 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
the Vigor Modem’s, you can let Relay Agent help you to redirect
the DHCP request to the specified location.
Enable Server - Let the modem assign IP address to every host in
the LAN.
Disable Server – Let you manually assign IP address to every host
in the LAN.
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 modem 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 modem, which means the modem is the default gateway.
DNS Server
Configuration
26
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
Vigor120 Series User’s Guide
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 modem 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 modem 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 modem 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
modem will resolve the domain name immediately. Otherwise, the
modem 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.
3.2.3 Static Route

Add Static Routes to Private and Public Networks
Here is an example of setting Static Route in Main Modem so that user A and B locating in
different subnet can talk to each other via the modem. Assuming the Internet access has been
configured and the modem works properly:
z
use the Main Modem to surf the Internet.
z
create a private subnet 192.168.10.0 using an internal Modem A (192.168.1.2)
z
create a public subnet 211.100.88.0 via an internal Modem B (192.168.1.3).
z
have set Main Modem 192.168.1.1 as the default gateway for the Modem A
192.168.1.2.
Before setting Static Route, user A cannot talk to user B for Modem A can only forward
recognized packets to its default gateway Main Modem.

1.
Go to LAN page and click General Setup, select 1st Subnet as the RIP Protocol
Control. Then click the OK button.
Note: There are two reasons that we have to apply RIP Protocol Control on 1st
Subnet. The first is that the LAN interface can exchange RIP packets with the
neighboring modems via the 1st subnet (192.168.1.0/24). The second is that those
hosts on the internal private subnets (ex. 192.168.10.0/24) can access the Internet
via the modem, and continuously exchange of IP routing information with different
subnets.
2.
Click the LAN - Static Route and click on the Index Number 1. Check the Enable
box. Please add a static route as shown below, which regulates all packets destined to
192.168.10.0 will be forwarded to 192.168.1.2. Click OK.
3.
Return to Static Route Setup page. Click on another Index Number to add another
static route as show below, which regulates all packets destined to 211.100.88.0 will be
forwarded to 192.168.1.3.
4.
Go to Diagnostics and choose Routing Table to verify current routing table.
Vigor120 Series User’s Guide

3.3 NAT
Usually, the modem serves as an NAT (Network Address Translation) modem. 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
modem, the modem will change its source address into the public IP address of the modem,
select the available public port, and then forward it. At the same time, the modem 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 modem’s public IP address
and the modem 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 modem. 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 for 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.
30
Vigor120 Series User’s Guide
Since the server is actually located inside the LAN, the network well protected by NAT of
the modem, 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 20 port-mapping entries for the internal hosts.
Press any number under Index to access into next page for configuring port redirection.
Vigor120 Series User’s Guide
31
Enable
Check this box to enable such port redirection setting.
Mode
Two options (Single and Range) are provided here for you to
choose. To set a range for the specific service, select Range. In
Range mode, if the public port (start port and end port) and the
starting IP of private IP had been entered, the system will calculate
and display the ending IP of private IP automatically.
Service Name
Enter the description of the specific network service.
Protocol
Select the transport layer protocol (TCP or UDP).
WAN IP
Select the WAN IP used for port redirection. There are eight WAN
IP alias that can be selected and used for port redirection. The
default setting is All which means all the incoming data from any
port will be redirected to specified range of IP address and port.
Public Port
Specify which port can be redirected to the specified Private IP
and Port of the internal host. If you choose Range as the port
redirection mode, you will see two boxes on this field. Simply type
the required number on the first box. The second one will be
assigned automatically later.
Private IP
Specify the private IP address of the internal host providing the
service. If you choose Range as the port redirection mode, you will
see two boxes on this field. Type a complete IP address in the first
box (as the starting point) and the fourth digits in the second box
(as the end point).
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 modem 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 modem in order to avoid confliction.
For example, the built-in web configurator in the modem 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 modem’s http port to any one other than the default port 80 to avoid
32
Vigor120 Series User’s Guide
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
modem 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.
Vigor120 Series User’s Guide
33
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.

save the setting.
3.3.3 Open Ports
Open Ports allows you to open a range of ports for the traffic of special applications.
Common application of Open Ports includes P2P application (e.g., BT, KaZaA, Gnutella,
WinMX, eMule and others), Internet Camera etc. Ensure that you keep the application
involved up-to-date to avoid falling victim to any security exploits.

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
modem 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 modem to build an unwanted outgoing connection.
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
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 modem 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 modem.
The following illustrations are flow charts explaining how modem will treat incoming traffic
and outgoing traffic respectively.
Vigor120 Series User’s Guide
37
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 modem not just
examine the header information also monitor the state of the connection.
URL Content Filter
To provide an appropriate cyberspace to users, Vigor modem 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 modem 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.
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 modem 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.
38
Vigor120 Series User’s Guide
Also the Vigor modem 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 modem 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. Port Scan attack
5. IP options
6. Land attack
7. Smurf attack
8. Trace route
9. SYN fragment
10. Fraggle attack
11. TCP flag scan
12. Tear drop attack
13. Ping of Death attack
14. ICMP fragment
15. Unknown protocol
Below shows the menu items for Firewall.
4.4.2 General Setup
General Setup allows you to adjust settings of IP Filter and common options. Here you can
enable or disable the Call Filter or Data Filter. Under some circumstance, your filter set can
be linked to work in a serial manner. So here you assign the Start Filter Set only. Also you
can configure the Log Flag settings, Apply IP filter to VPN incoming packets, and Accept
incoming fragmented UDP packets.
Click Firewall and click General Setup to open the general setup page.
Call Filter
Check Enable to activate the Call Filter function. Assign a start
filter set for the Call Filter.

Filter
Select Pass or Block for the packets that do not match with the
filter rules.
Log
For troubleshooting needs you can specify the filter log by checking
the box. The log will be displayed on Draytek Syslog window.
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 modem will reject these
fragmented packets to prevent attack unless you enable “Accept large incoming
fragmented UDP or ICMP 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 large
incoming fragmented UDP or ICMP 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.
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 modem 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 modem.
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 modem 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 modem
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
Port Scan attacks the Vigor modem by sending lots of packets to
Vigor120 Series User’s Guide
45
detection
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 modem will send out a
warning. By default, the Vigor modem sets the threshold as 150
packets per second.
Block IP options
Check the box to activate the Block IP options function. The Vigor
modem 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 modem 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

reject this kind of packets.
Warning Messages
We provide Syslog function for user to retrieve message from Vigor
modem. The user, as a Syslog Server, shall receive the report
sending from Vigor modem 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.
3.4.5 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.
Vigor120 Series User’s Guide

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

3.6 Applications
Below shows the menu items for Applications.
3.6.1 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 modem 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 modem to update its online WAN IP address mappings on the
specified Dynamic DNS server. Once the modem is online, you will be able to use the
registered domain name to access the modem or internal virtual servers from the Internet. It
is particularly helpful if you host a web server, FTP server, or other server behind the
modem.
Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the
DDNS service providers. The modem provides up to three accounts from three different
DDNS service providers. Basically, Vigor modems 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 modem.

3.6.2 Schedule
The Vigor modem 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 modem 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 and Date
menu, press Inquire Time button to set the Vigor modem’s clock to current time of your PC.
The clock will reset once if you power down or reset the modem. There is another way to set
up time. You can inquiry an NTP server (a time server) on the Internet to synchronize the
modem’s clock. This method can only be applied when the WAN connection has been built
up.

3.6.3 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
modems, the major feature of UPnP on the modem is “NAT Traversal”. This enables
applications inside the firewall to automatically open the ports that they need to pass through
a modem. It is more reliable than requiring a modem 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 modem provide 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
Modem 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.
Vigor120 Series User’s Guide
59
The UPnP facility on the modem enables UPnP aware applications such as MSN Messenger
to discover what are behind a NAT modem. The application will also learn the external IP
address and configure port mappings on the modem. Subsequently, such a facility forwards
packets from the external ports of the modem 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.
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 modem functions, including removing and
adding port mappings.
60
Vigor120 Series User’s Guide
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.

Application and Examples
4.1 LAN – Created by Using NAT
An example of default setting and the corresponding deployment are shown below. The
default Vigor modem 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.
You can just set the settings wrapped inside the red rectangles to fit the request of NAT
usage.
