Gnugk 2.0.8 works fine with endpoints behind NAT, and has the config options mentioned. It's normal for GCF to show the public address. I have never seen the registration problem you describe. IMHO you should debug it by running Ethereal on both sides of the NAT. On the LAN side, if the phone is hardware, then you will need a dumb hub or a managed switch, so the PC running Ethereal can see the packets to and from the phone. On the WAN side, running Ethereal on the gnugk machine should be fine. Does the phone see the GCF packet? You can tell if it isn't, because it will retry GRQ several times, so you will see several GCFs from gnugk. If that's the case, conceivably the phone is sending the GRQ on port 1718 (it should be using 1719 for unicast GRQ) and gnugk is responding from 1719. Otherwise, the NAT must be dropping or butchering the GCF. There should be no forwarding needed for GRQ and GCF. If the phone gets the GCF, then what happens to the RRQ? This is also a simple outgoing UDP packet and the NAT should pass it, without forwarding. --Stewart ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
