Hi Terry, If the GK has a private IP and is behind a NAT router, then you must set NetworkInterfaces to specify the private and public addresses. For example, if the GK has IP 192.168.0.100 and the NAT has public IP 1.2.3.4, then set NetworkInterfaces=192.168.0.100/24,1.2.3.4/0 Also, you have to configure the NAT to forward required ports to the GK. Since registration is working, you probably have already forwarded UDP 1719. You also should forward TCP 1720, and any required H.245 and RTP ports. If all your endpoints work properly with H.245 tunneling, or they can use fast start and don't need any advanced calling features, then you won't need H.245 ports. Otherwise, assign a range with H245PortRange and forward those TCP ports across the NAT. Assuming that you have administrative control of any NATs with endpoints behind them, then you can probably turn off all the [Proxy] options, and you won't need any RTP ports for the GK. Otherwise, assign a range with RTPPortRange and forward those UDP ports across the NAT. If an endpoint is behind a NAT, you need to forward TCP 1720 to it, as well as RTP ports and possibly H.245 ports. See the endpoint documentation to know which ports are used. The RCF console message should show both the private and the public IP addresses. If the endpoint has a public IP, you need to open the above mentioned ports on the firewall. If it still doesn't work, please state what kind of endpoints you are using, what types of NATs or other routers are involved, what version of gnugk you are running on what platform, and what goes wrong (e.g. called phone rings but there is no audio in either direction). Also, include some trace output from the GK, and any debug info provided by the endpoints. --Stewart ----- Original Message ----- From: "TERRY HE" <terry.he@xxxxxxxxx> To: <openh323gk-users@xxxxxxxxxxxxxxxxxxxxx> Sent: Saturday, December 11, 2004 7:18 PM Subject: Can't reply problem > Hi, all, > > > > I got a weird program.
