Hi, thanks for the reply...

Is 11999 for games? I don't want to allow games access.

Didn't quite understand this bit. 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?
