Hi,
Has anyone had any experience for allowing Yahoo voice chat and
net2phone through a firewall. I want to only allow it for certain
users but I can't seem to work out the ports that it is using for the
voice chat. Any one done this before?
Thanks,
Abdul-Wahid

Why would the second UDP port not need to be specified as by default I am dropping all UPD. Unless there is a connection tracking module that knows about this voice chat and can work out that it is a RELATED connection. Also, the work stations are NAT'd and have private addresses. They want to be able to make and recv. voice chats. Does that mean I have to open all UDP ports from 1-30000 for the workstations needing voice chat?
