ok i know a couple of things that could possibly be wrong

1. my firewall
2. my router?
3. ip ban (wasnt this referred to as realm down a while back?)
4. my isp

i have norton security center, and a lynksus(sp) router. im on wireless internet called advantek.

if any of you know how to add exceptions / open ports. or tests i can do to figure this out, it would all be greatly appreciated.
