7. 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 comput-
er. 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:
A. Access the Router’s web interface by going to
http://192.168.1.1
or the
IP
address
of the Router. Go to the
Advanced => Port Forwarding
tab.
B. Enter any
name
you want to use for the Customized Application.
C. Enter the
External Port range
of the service you are using. For example,
if you want to host Unreal Tournament (UT), you would enter the range
7777 to 27900.
D. Check the
protocol
you will be using, TCP and/or UDP.
E. Enter the
IP address
of the PC or network device that you want the port
server to go to. For example, if the web server’s Ethernet adapter IP address
is 192.168.1.100, you would enter 100 in the field provided. Check
“Appendix D: Finding the MAC Address and IP Address for Your Ethernet
Adapter” for details on getting an IP address.
F. Check the
Enable
option for the port services you want to use. Consider the
example below:

of the web interface. If you assigned a static IP address to any computer or net-
work 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. Refer to “Problem #7, I need to set up online
game hosting or use other Internet applications” for details.

6. I need to set up a server behind my Router and make it available to the public.
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.
A. Access the Router’s web-based utility by going to
http://192.168.1.1
or the
IP address
of the Router. Go to the
Advanced => Port Forwarding
tab.
B. Enter any
name
you want to use for the Customized Application.
C. Enter the
External Port range
of the service you are using. For example,
if you have a web server, you would enter the range 80 to 80.
D. Check the
protocol
you will be using, TCP and/or UDP.
E. Enter the
IP address
of the PC or network device that you want the port
server to go to. For example, if the web server’s Ethernet adapter IP address
is 192.168.1.100, you would enter 100 in the field provided. Check
“Appendix D: Finding the MAC Address and IP Address for Your Ethernet
Adapter” for details on getting an IP address.
