like AIM, morpheus, and diablo II, do i need to open these ports on my firewall? i'm using a linux box with iptables, using a pretty standard iptables script, do i even need to do anything or will these programs work fine?

On my OpenBSD machine I have it setup so anything can go out and almost nothing in. I havent had problems recieving files through DCC, but I cant send. I dont play games so I dont know the answer to the other question. As far as ports 1024+, they are "less important" than the smaller ports and can be left open if you really need to.

do a search in this forum for "ports", there is one with 10 replies about ICQ, thats the one.

n0c - mine will be set up so that anything can go out and http/ftp/ssh/ident can come in. i think i'm just gonna give it a try that way and go from there.

Definitely start out that way. The logs you get should show you what you need to open, if anything. I only allow http and ssh in.
