Thanks jan H323 signaling is works in this scenario, but not getting media
on any sides.

*H323 client 1 (192.168.120.196) <---->(Router public
IP=203.187.yyy.xx)<------->( IP world )<-----> GateKeeper (public
ip=124.30.y.xx)* <-------->H323 client 2 (192.168.7.63)
*
I have configured gnugk in *Case III* (Proxy) mode as described in  the
link: http://www.gnugk.org/gnugk-manual-5.html#proxy

and below is the details:

[Proxy]
Enable=1
;InternalNetwork=10.0.1.0/255.255.255.0,127.0.0.0/8
;T120PortRange=40000-40999
RTPPortRange=7000-59999
ProxyForNAT=1
ProxyForSameNAT=1
EnableRTPMute=1
EnableRTCPStatus=1

below is the gnugk log messages

2012/09/21 12:11:20.499    3    ProxyChannel.cxx(7278)    RTP

does any other configuration require gatekeeper side?



Thanks in Advance

Hi,

just turn on H.460.18 in GnuGka and this scenario should work.

BTW: This is the kind of question for the GnuGk users mailinglist.
