If both clients are in behind NAT and in different Network. Both can listen but cann't call each other successfully and got an error message "call to username aborted, insufficient bandwidth"
My gatekeeper is running on public IP(184.108.40.206). In my concern, we are using SMC7008ARB NAT router. It is a hardware part. It is not a linux machine. I am using GNUGK v2.0.2. In the client side openphone & ohphone is available.
Client 1 registers to GK with alias clt1
Client 2 registers to GK with alias clt2
Client 1 and Clinet2 are in behind NAT
Client2 calls "clt1" or Client1 calls "clt2".
In ohphone, Both clients are using "--translate" option (for masquerading).
In the above status, client1 is registered in public GK and waiting for incoming call. when Client 2 call to client1. Client2 is registered in GK and request is going to Client1 NAT router at port 1720 at this time NAT router couldn't establish a new connection to the local system. I fell that is the limitation. Is it correct?.
I wish to establish the connection additionally in 1720 at the time of registration. with minimum code changes(Time factor). Once connection is established packet will send both side. I feel that would lead to the solution.
My public GNUGK config
My Public GK config file
Thanks in advance.
