Hi all, I've had a good read of the posts here, all of which have been very helpful, however, I would like a bit of advice as I seem to have run out of ideas.... I have on my lan here, a ip200 voip phone chatting to the openh323gk which is on my firewall/router/nat/iptables box. I've configured the GK such that it will chat out to my friend who has a similar setup - i.e. phones that I register here are being registered on his GK. The problem comes though when we start the call, the call is setup, but the packet payload of the actual h323 stuff seems to contain the internal IP addresses for both phones which are of course private addresses. I've put a network diagram on line at http://pjm.dyndns.org/voip.jpg or http://pjm.uhf-satcom.com/voip.jpg I'd really appreciate a pointer as to what to do next in order to get our phones chatting.... regards, Paul. http://www.frars.org.uk __________________________________________________ Yahoo!
