These days I am evaluating different type of VoIp gateways. I did managed to place two gateways behind two separate NATs and I am able to connect either of one from any of the othe gateway. Both the gateways are placed in peer to peer mode.
However, when I tried to connect to either of these gatewasy from Netmeeting (using a Public IP address) I am unable to connect if I only use IP of the router at my network.
I have tried many soft h.323 clients. But none of the clients have option to add E.164 number of the gateway port.
H.323 was not designed for nat, it is a waste of time to try and get it to work behind nat when SIP is a more friendly protocol. If you do get it to work, will it be worth the time and effort? Is there any reason why you absolutely have to use h.323? mattg@telcomproducts.com
May be your solution is to use a gatekeeper. I had a lot of trouble trying to set up two of my gateways behind a NAT. The solution came with a gatekeeper from openh323.org. Good luck.
