How to setup a Minecraft Server with port forwarding with Norton security suite version 5.2.0.13

Ok, I want setup a server for a game called Minecraft, I looked at every tutorial out there.  Port I need open is 25565, but no matter what I do I can't get it open, and I know its the Norton security suite fault because my friends who do have a server working don't have Norton security suite. Please sent me a easy to follow how-to-guide, so I can have my own server.

My system info
I am using a wireless internet for my computer
windows 7 ultimate
32-bit operating system
Linksys Router WRT54G

Thank you for reading.

Sincerely, Daniel Pace
