VIP-101T does not perform anything unusual regarding NAT. Maybe the problem is with some cheap NAT router between? I found some series of Planet/D-Link routers to mess up with H.323 signalling in some cases. This prevented GnuGk from detecting that an endpoint is behind a NAT.

Hi all,
Previously I have asked about gnugk as a proxy server. After I will to
deal with two Windows Netmeeting client with either one NATed, it works
prefectly. But if one of the side using the phone, it didn't work. So i am
suspecting this Planet VIP-101T support proxy or not. Anyone comes up with
any idea? Thanks!
Yours sincerely, Jason Chan
Hi Jason,
Don't give up on the Planet yet. A phone (or other endpoint) does not need
to "support" a proxy. The whole idea of a proxy is that it appears as an
endpoint to the calling phone. When the phone makes a call through a
proxy GK, *all* communication sent and received by the phone should be
with the GK. The phone should not even be able to tell that it is not talking
to a normal endpoint.
Some endpoints implement various schemes to deal with NAT, and these sometimes conflict with gnugk. Try turning off any NAT or STUN features in the phone.
If that doesn't help, use Ethereal on the 192.168.0.1 interface to see where the phone is told to send to a public IP address. It seems likely that this is happening, because the behavior changed when you set a router address in the phone. If all packets from the phone were destined for 192.168.0.1, then the router address would not have mattered.
Regards,
Stewart
