Hi All I am new to this list and would first like to thank all of you for the great work you have achieved so far. I am trying to use gnugk in the following configuration Sjphone (from sjlabs.com) on PC1 (192.168.0.101) connected to a NAT BOX (Windows ICS) with private IP 192.168.0.1 and public IP 111.111.111.111 The phone endpoint is registered to a gk box with public IP and calling an IP phone with public IP When I call from Sjphone to the Ip phone, I get ring, call connect but I can't get any voice on any party. When I look at log and also ports opened on PC1, I find that the GK is sending all messages to the NAT public IP 111.111.111.111. When I remove the GK and call in IP to IP mode, it work fine and I find that the softphone connect using the NAT box private IP address for voice traffic. Since gnugk use NAT box public IP, how can I make sjphone work if it require the NAT private IP (sjphone uses STUN ) Can anyone help Thanks Hubert __________________________________ Do you Yahoo!?
