I am running WinXPpro connected to the internet via a cable modem and roadrunner. My computer is networked with another XP machine and one win98se machine via a Dlink cable router/switch. My question is, the router has a built in firewall, and I was wondering if I need to setup the proxy option in my programs (ie. IMchat, webcam, gamespy, etc)? My chat programs work fine and I havn't really tried internet games yet, just wondered if the firewall made the proxy setup necessary. Thanks!
