[shejuti hossain <shanta8@xxxxxxxxx>]

Hello there,

In my country all ports r block for voip service so i setup a VPN(im using openvpn) system between two linux server(one in usa and one
in my home) and i make a turnel between two machine and its working fine. i can send data through that tunnal from one to another.one ip is 10.7.0.78(usa side) and 10.7.0.77(my home side).In both server i setup gnugk to route calls from usa(gk1) to my country(gk2 as parent).my home machine has two lan(192.168.0.1, 202.x.x.45(real ip)). now when call is send to usa's real ip(70.x.x.44) its come to my home's ip' gnugk but cant route to gateway which ip is 192.168.0.30.in usa side gnugk in log disconnect cause =3 and in my
home gnugk show disconnect cause=16 or 41. my quintum gateway(gw1 192.168.0.30 ) which is connected to my home server can register with myhome gk as gw1.from quintum  i can ping usa server ip(10.7.0.78).ip forwarding is enable in both server.when i send call to my home gk for test it send call
to my gateway but when call send to usa, its not terminated to my gw1.
