Hi,

Thanks for reply.

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>


I have following scenario right now:

(Endpoint1 192.168.0.18) -> (192.168.0.1 OpenBSD NAT 202.179.x.x) -> (GNUGK 202.179.x.x) ->

-> (202.131.x.x FreeBSD NAT 192.168.32.1) -> (Endpoint2 192.168.32.5)

Do you think this will work in this case?


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.

As I said before I have FreeBSD and OpenBSD NATs, do you think it will fork for my case?



thanks in advance,

Ganbold


Regards,
Igor
