I don't think so. I can post the complete IPTABLES status if it helps.

The Enable IP translation box was not checked. I guess that must be
the problem.

I've checked it now.

Could you call me so I can check it is working?

BTW, what is an acceptable h323: address.

h323:80.177.30.27 seemed to work as far as getting a ringinging tone (this was from netmeeting),
but h323:colin colina demon co uk does not seem to.
