While goofing around on Trillian (a multi-chat for the uninformed) I noticed that it displays IP's for people on ICQ. then I noticed that several AK'ers IP's are displayed as 0.0.0.0. Namely Pix and Palooka (at this time). What kind of security functions do you have to prevent such things from being displayed?

Im fairly new at this firewall/router stuff. I was lazy so I bought a nice Linksys router/firewall. and its exactly as easy to use as id hoped.
