One more thing, hehe.... here is my new config file: [Gatekeeper::Main] Fourtytwo=42 TimeToLive=600 NetworkInterfaces=10.42.42.16/24,w.x.y.z/24,127.0.0.1/8,172.16.250.16/24 [RoutedMode] GKRouted=1 H245Routed=1 CallSignalPort=1721 AcceptUnregisteredCalls=1 SupportNATedEndpoints=1 ;AcceptNeighborsCalls=1 Q931PortRange=20000-20249 ;TCP H245PortRange=20250-20449 ;TCP [Proxy] Enable=1 T120PortRange=20500-20749 ;TCP RTPPortRange=20750-20999 ;UDP ProxyForNAT=1 ProxyForSameNAT=1 [GkStatus::Auth] rule=allow Default=allow -------------------------------------------------------------- I'm forwarding 20000-20749 through, TCP only, and 20750-20999 UDP only. The connections still don't work, and it looks like GnuGK is ignoring my port ranges completely. root@server:~# netstat -anp |grep openmcu tcp 0 0 0.0.0.0:1720 0.0.0.0:* LISTEN 2396/openmcu udp 0 0 10.42.42.16:17142 0.0.0.0:* 2396/openmcu Here's openmcu's connection which is on the same server as GnuGK, and it looks like it's using port 17142? Or am I getting this wrong? baseline:~# netstat -anp |grep ohp tcp 0 0 0.0.0.0:1720 0.0.0.0:* LISTEN 1491/ohphone tcp 0 0 10.42.42.249:32783 10.42.42.16:1721 ESTABLISHED1491/ohphone udp 0 0 10.42.42.249:5002 0.0.0.0:* 1491/ohphone udp 0 0 10.42.42.249:5003 0.0.0.0:* 1491/ohphone udp 0 0 10.42.42.249:32788 0.0.0.0:* 1491/ohphone Above is ohphone connecting to ConferMCU, it's on the same network as the GnuGK, but on a different computer. I noticed none of those ports are in the 20,000 range. I'm not sure what's going on :p. And here is ohphone on the non-GnuGK network, connected to the gatekeeper, but can't reach ConferMCU for "some reason". LocalComp:~# netstat -anp |grep ohp tcp 0 0 0.0.0.0:1720 0.0.0.0:* LISTEN 7927/ohphone udp 0 0 10.10.10.156:1060 0.0.0.0:* 7927/ohphone Is there something blatantly obvious that I'm missing? I run gnugk with this command: gnugk -ttttt -c /path/proxy.ini -rr Ohphone has a "-p" option to define a proxy, but it doesn't seem to change the outcome of the connection, maybe I'm not understanding proxies very well....any help is appreciated. ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
