I configured opengk 2.0.5 on a debian linux box as proxy. pc1@Internet <-> [Nat box, gnugk proxy] <-> pc2@192.168.0.0/24 Both pc1 & pc2 can register, Both pc1 & pc2 can call each other When pc2 calls pc1, every thing is ok When pc1 calls pc2, voice is bad (openphone log shows many lost packets) Control signals (ring/start/stop) seem to be transmitted correctly in both directions The Nat box is an iptables forwading that accepts udp & tcp above 1024. iptables -F; iptables -t nat -F; iptables -t mangle -F; iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE; iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT; iptables -A INPUT -m state --state NEW -i ! ppp0 -j ACCEPT; iptables -P INPUT DROP; iptables -A FORWARD -i ppp0 -o ppp0 -j REJECT; iptables -A INPUT --protocol tcp --dport 1024:65536 -j ACCEPT iptables -A INPUT --protocol udp --dport 1024:65536 -j ACCEPT echo 1 > /proc/sys/net/ipv4/ip_forward The gnugk .ini is [Gatekeeper::Main] Fourtytwo=42 Name=h323gk TimeToLive=600 EndpointIDSuffix=_ep [RoutedMode] GKRouted=1 H245Routed=1 CallSignalPort=1720 CallSignalHandlerNumber=2 AcceptUnregisteredCalls=0 RemoveH245AddressOnTunneling=0 DropCallsByReleaseComplete=1 SendReleaseCompleteOnDRQ=1 SupportNATedEndpoints=1 H245PortRange=30000-30019 Q931PortRange=30020-30039 [RasSrv::ARQFeatures] CallUnregisteredEndpoints=1 [Proxy] Enable=1 InternalNetwork=192.168.0.0/24,127.0.0.1/8 ProxyForNAT=1 ProxyForSameNAT=0 T120PortRange=50000-50019 RTPPortRange=50000-50019 #Plus other radauth stuffs .... In the manual of gnugk, I read: Since 2.0.2, the GnuGK supports NAT outbound calls (from an endpoint behind NAT to public networks) directly without any necessary modification of endpoints or NAT box. Just register the endpoint with the GnuGK and you can make call now. This is true because I tested it successfully. What about inbound call? Notice that I didn't apply the iptables h323 kernel patch and i don't want to.
