On 10 Mar 2002 in that fucked up hellhole known as comp.security.firewalls, an identity claiming to be Ram spewed forth news:5eba6d26.0203102132.17c37640@posting.google.com: > I use Yahoo Messenger at office and there is a corporate firewall. It > does not allow any incoming traffic on any other port than the well > known ones. But If I configure the connection in Yahoo messenger > telling that I am behind a firewall it was able to connect . > I was curious to know how it was able to do that..not only messenger > but other file sharing applications.. > Dows anybody have any ideas? > > Ram > Yahoo messenger prefers port 5xxx (don't remember the exact port) and will try to use that. However, it's also capable of using port 80 to slip through the firewalls, which is what you're telling it to do when you check the 'behind firewall' box. -- ThePsyko Public Enemy #7 "God told me to skin you alive" http://prozac.iscool.net
