Hi.
Thanks for your answer. But you didn't understand my question.
In your article described about instant messaging, not AV conversation.
I need video and audio conferencing through ISA server and I don't whant
open many incoming ports om my firewall.
How I can do it?
P.S. Is it secure for my internal network to open many incoming ports on
firewall? I think it isn't.
