Roger,
Here is a quote from one of Charles's earlier posts on the subject....
I don't work a lot with h323, but I think you need the following:
1) Make sure you're loading the ip_masq_h323.o module in /etc/modules
2) To be able to recieve calls, you need to port-forward some ports from
the firewall to the internal system you want to be able to recieve
calls. With Dachstein, you'll want something like:
INTERN_SERVERS="tcp_${EXTERN_IP}_1720_10.31.32.67_1720
tcp_${EXTERN_IP}_1503_10.31.32.67_1503"
More information can be found on various linux masquerading pages, and
the home-page of the h323 masquerading patch:
http://www.coritel.it/projects/nat/index.html
You might also want to check into running a proxy...either a socks proxy
(if supported by your h323 client), or a h323 proxy, like openh323proxy:
