We've had it working in the past through our ISA server, not sure if anyone is using it now though. Skype is pretty adept at finding ways through firewalls, so I don't think I had to create any specific rules for it here either. The question we had before was how to block it...

I don't think I had to create any special rules at all. I took a look at my firewall policy and I've got no rules for Skype. I may have allowed traffic on a special port, but I'm not sure.

I am running 2004 and have been asked to get Skype working with video through the isa firewall. I have done some reading but no recent experiences. Can anyone point me in the right direction to get this working? Thanks JK
