Subject: Re: Is there anybody tested under such NAT circumstance?
Date: Mon, 6 Sep 2004 15:14:47 +0200
Try the following. With this config I can connect from outside to a client behind the NAT box (gnugk 2.08). The proxy must be on the NAT box and must accept the specified ports..
What I want to know. The default value for CallSignalPort is 1721. Therefore I expectet that the proxy will return this port in the transport address, but the client (ohphone) wnat to connect to 1720.
[RoutedMode] GKRouted=1 H245Routed=1 CallSignalPort=1720 RemoveH245AddressOnTunneling=1 DropCallsByReleaseComplete=1 SupportNATedEndpoints=1 AcceptNeighborsCalls=1 Q931PortRange=some range H245PortRange=some range
[Proxy] Enable=1 InternalNetwork=192.168.0.0/16 T120PortRange=some range RTPPortRange=some range
