Port forwarding is a
method that allows you to run a server behind the router. Port Forwarding
opens a specific port to a computer behind the router, allowing all Incoming
Traffic on that port to be sent directly to that server. It should be
used to setup servers behind the router, typically Port Triggering (Answer ID 344) is a better choice for non server
applications (Such as instant messengers and game servers).
Below is an example of
how to setup Port Forwarding. For our example we will be setting an FTP
Server and a Mail Server that uses SMTP and POP3.
FTP uses ports:
20 and 21
SMTP uses port: 25
POP3 uses port: 110
1. You must set a
static IP address on the server. If you're unsure of how to do this
please go to Answer ID 534 for information on setting a static IP
address in Windows.
2. Once the static IP
address has been assigned please go to your desktop and double click on Internet
Explorer (Located on the Start Menu in Windows XP)
3. Once "Internet
Explorer" opens, please type http://192.168.1.1into the "Address
Bar" and click GO
4. The "Enter
Network Password" window will appear. Skip user name and type admin (admin
is the default password) as the password, and click OK
5. This will bring up
the routers "Setup" section. Look under "Domain Name"
and check what version of the firmware you're using.
6. You will need to
click on the Advanced tab to the very right. Once the
"Advanced" tab comes up please go to the Forwarding tab.
