number used in the VPN IP address), the Router will have
difficulties routing information to the right location. If
you change the Router's IP address to 192.168.2.1, that
should solve the problem. Change the Router's IP address
through the Setup tab of the Web-based Utility. If you
assigned a static IP address to any computer or network
device on the network, you need to change its IP address
accordingly to 192.168.2.Y (Y being any number from 1 to
254). Note that each IP address must be unique within the
network.
Your VPN may require port 500/UDP packets to be passed
to the computer that is connecting to the IPSec server.

I need to set up a server behind my Router.
To use a server like a web, ftp, or mail server, you need
to know the respective port numbers they are using. For
example, port 80 (HTTP) is used for web; port 21 (FTP) is
used for FTP, and port 25 (SMTP outgoing) and port 110
(POP3 incoming) are used for the mail server. You can get
more information by viewing the documentation provided
with the server you installed. Follow these steps to set up
port forwarding through the Router's Web-based Utility.
We will be setting up web, ftp, and mail servers.
1. Access the Router's Web-based Utility by going to
http://9.8.. or the IP address of the Router. Go
to the Firewall -> Port Forwarding tab.
2. Select the Service from the Application column.
3. Enter the IP Address of the server that you want the
Internet users to access. For example, if the web
server's Ethernet adapter IP address is 192.168.1.100,
you would enter 100 in the field provided. Then check
the Enable checkbox for the entry. Consider the
examples below:
Appli- Start Proto-
cation and End col
HTTP 80 to 80 Both
FTP 21 to 21 TCP
SMTP
25 to 25 Both

POP3 110 to

I need to set up online game hosting or use other Internet
applications.
If you want to play online games or use Internet
applications, most will work without doing any port
forwarding or DMZ hosting. There may be cases when you
want to host an online game or Internet application. This
would require you to set up the Router to deliver incoming
packets or data to a specific computer. This also applies to
the Internet applications you are using. The best way to
get the information on what port services to use is to go
to the website of the online game or application you want
to use. Follow these steps to set up online game hosting
or use a certain Internet application:
1. Access the Router's Web-based Utility by going to
http://9.8.. or the IP address of the Router. Go
to the Firewall -> Port Forwarding tab.
2. Select the Service from the Application column.
3. Enter the IP Address of the server that you want the
Internet users to access. For example, if the web
server's Ethernet adapter IP address is 192.168.1.100,
you would enter 100 in the field provided. Then check
the Enable checkbox for the entry. Consider the
examples below:

I can't get an Internet game, server, or application to work.
If you are having difficulties getting any Internet game,
server, or application to function properly, consider
exposing one PC to the Internet using DeMilitarized
Zone (DMZ) hosting. This option is available when an
application requires too many ports or when you are not
sure which port services to use. Make sure you disable all
the forwarding entries if you want to successfully use DMZ
hosting, since forwarding has priority over DMZ hosting.
(In other words, data that enters the Router will be checked
first by the forwarding settings. If the port number that
the data enters from does not have port forwarding, then
