I believe I am behind a firewall.

I am using my personal computer at home with cable modem. I do use ZoneAlarm which is a firewall program, but have given Gnutella free access. I've also tried with Gnotella and same thing happens. In addition, I'vv e turned off ZoneAlarm and still cannot get connected.

I use AT&T's roadrunner service which I believe has a firewall of its own, but I'm not sure.

Any ideas?
