H323 and NAT

Does H.323 work with NAT?

The issue is this. We have a customer who is using Netmeeting behind a 905 ubr Cable/Modem Router. They use NetMeeting as a means to pass small video presentations. They have stated that for 6 months this worked behind NAT and Firewall with no issues. Now they can call out, and I can accept a call but it does not pass data back to them.

Is this going to be possbile? Any ideas woud apperciated

Re: H323 and NAT

I think the first session through may work but not additional simultaneous sessions. I would look at the logs and see what’s dropping or being denied but I think they’re going to have to get enough real IP addresses for all their netmeeting hosts to translate to.
