Dear all: I use Debain/Linux run Gnugk 2.2.0 and ohphone. they are : 1)A is Debian/Linux and run Gnugk 2.2.0, it's IP is 192.168.1.57 and i config my gateway's firewall to make 192.168.1.57 map 211.111.111.57. 2)B is Debian/Linux and run ohphone with IP: 192.168.0.138, and i config my firewall not to filter any packet to this IP. now, B run: ohphone -g 211.111.111.57 -u sandy -l, it telles me that can not regist on gnugk. I use ethereal to capture packets and find these packets: 192.168.0.138 211.111.111.57 H.225.0 RAS: gatekeeperRequest 211.111.111.57 192.168.0.138 H.225.0 RAS: gatekeeperConfirm 192.168.0.138 192.168.1.57 H.225.0 RAS: registrationRequest 192.168.0.138 192.168.1.57 H.225.0 RAS: registrationRequest It is so strange, When B send registrationRequest to A, it should send to 211.111.111.57 but not 192.168.1.57. why? my gatekeep.ini is: [Gatekeeper::Main] Fourtytwo=42 Name=OpenH323GK [RoutedMode] GKRouted=1 AcceptUnregisteredCalls=1 SupportNATedEndpoints=1 H245PortRange=30000-30010 Q931PortRange=30011-30020 [RasSrv::ARQFeatures] CallUnregisteredEndpoints=1 [Proxy] ;Enable=1 RTPPortRange=5000-5010 [GkStatus::Auth] rule=allow [Gatekeeper::Auth] default=allow I run my GK with these commands: gnugk -r -ttt any ideas, thx very much ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
