Q:
Is it possible to use net2phone behind NBM? I'd like my one of my internal machine to act like its connected to public network. I made a NAT binding private=public.
How can I configure NBM so this internal machine can pass any traffic UDP/TCP? Do I need configure filters? When I UNLOAD IPFLT it works, otherwise not ...
A:
You need to figure out what port numbers the application uses, so you can set up custom filter exceptions. Here are three ways to do that:
1) Use Filter Debug on the server.
2) Use Ethereal (packet capture) on the workstation to see what is being requested.
3) Run netstat at the dos prompt of the workstation when the connection is established, and see the port protocols used in the communication.
