I have two computers on a workgroup through dsl and 2 port router. One computer has ZoneAlarm firewall and the other is just using the XP Firewall. When I go to the settings of the XP firewall I can add a IP address...like a trusted IP im guessing...It also asks for the incoming and outgoing ports? How can I find those....I want to be able to talk to each computer without turning the XP firewall off....any help? thanks, cody o
