The Vonage RT31P2 does not talk H.323, and it's not necessary to do anything other than plain vanilla NAT to have it work through a firewall. That is, no port forwarding, no SIP payload re-writing, etc. Just plain vanilla NAT for both the SIP signaling and the RTP payload will be all that's necessary. I use ipfw with my Vonage service, but there's nothing special that I do for NAT. I don't do ipf..
