It is easy. All you have to do is find the Default Gateway of your computer then access the router from there.

First go to Start then Click Run
on windows vista/7 just type in the Start Search cmd
Ok back to XP since I think you have XP. Now type in the run window cmd
and click ok.

Type ipconfig

Then get the IP for your computer. The output should look like this

Code:

Connection-specific DNS Suffix . : discoveryweb.co.cc
Link-local IPv6 Address . . . . . : <hidden for secure reason :)> 
IPv4 Address. . . . . . . . . . . : 192.168.1.103
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

I am on windows 7 so I am not very sure if it will be the same output but It should be. Now look for you Default Gatewa. Mine is 192.168.1.1. Yours should look the same or it might be 192.168.0.1


Any ways just get the default gateway

Go to Internet Explorer or any web browser then type that Default Gateway

Now your router page should show asking for the username and the password

All you have to do is search on ****** for the router name then default password and username.
After you login try and search for port forwarding in there.

If you didn't find it then just post a ss for your router or get the name and MODEL of it so I can check it in my base.
