If you want to setup such things as video conferencing (eg netmeeting)
Firewalls don't work very well with UDP eg:- Voice (voIP) video(video

I just signed up to this list so I hope I am not stepping in at the wrong place, but
if you are looking to do video conferencing over a masqueraded network MS Netmeeting
does work. I do it here at home. There is a module available from sofia.net (I hope

This is a masq_module for the H.323 protocol.

The reason why you can't use NetMeeting through a firewall (warning: second-

IP address in the _data_ portion of the traffic, rather than just letting
TCP/IP do its job. Server uses
