Hi Hubert, You have a complex situation, because sjphone is trying to traverse NAT, and your ICS (if that's the one also forwarding to your Indy FAX server) has the Telephony Service enabled, which also tries to do NAT traversal. Your GK (if that's the one on x.x.x.12) is listening on port 1721, which may be confusing Telephony. Try setting CallSignalPort=1720 . GnuGK will work fine (doing its own NAT traversal) if the endpoint and NAT do not alter the contents of any H.323 packets. Or, it will work fine if your endpoint / NAT combination appear to the GK as a non-NAT endpoint. You can run Ethereal on both PC1 and the GK to see whether and how the NAT is altering packets. If the console RCF message shows both the private and public addresses of PC1, then GK will assume that PC1 is behind a NAT and act accordingly. In this mode, the NAT must not alter any packets, and the endpoint must use its private address. If your application permits, you could try disabling Telephony. Sorry, I don't know how, if you just turn it off, ICS will also be stopped because it is 'dependent' on Telephony. Or, you could use nonstandard RAS and signaling ports to fool it. You may also need to manually forward media ports. Or, perhaps you could try a Linksys or other dumb router (on a different public IP) instead of ICS. If the RCF message shows only the public address, check that packets received at the GK are consistent with what a non-NAT endpoint would send, and that packets received at PC1 have been properly translated. In this case, the NAT should forward the media streams automatically.
