Which configuration do you mean? <1-st ep 192.168.1.1>--<192.168.1.254 NAT1 80.80.1.1>--<212.211.2.2 GNUGK> | <2-nd ep 192.168.2.1>--<192.168.2.254 NAT2 90.90.2.2> If you want to establish connection in described configuration, foget about it because not only headers of packets contains information about ip addresses and ports, but also internal contents of packets contains information about real ip address of an endpoint and used ports. And you need not only change the ip-header, but internal content too. In it is the purpose of the gatekeeper in full proxy mode. You need 2 gnugk's installed on both NAT boxes. And you can't use hardware NAT, only computer with two interfaces configured as gateway. Or you need hardware NAT with full h323-proxy functionality.
