Hi Chris Thanks for the answer. I am not familiar with H.323 at all. So it is a protocol using the TCP/IP and UDP protocols, isn't it? Which explains why some applications do and others don't work with gnatbox?
If I understand it right, then having set up an outbound filter for one particular machine (mine) to allow access through all protocols to all ports should work, shouldn't it? Has anyone else tried the www.hottelephone.com free internet to phone service with Gnatbox yet? Thanks again for your help.

I have some products that work great through GB Nat, and others that don't. Netmeeting will not do audio or video communications, but the other features will work. I have successfully used Net2Phone from behing GB without issue. If it does not work for you, then the only alternative is to use real IP's behind your firewall and run IP Passthrough.
