This has nothing to do with the Gatekeeper being behind a NAT, the 
gatekeeper is on the public internet now I understand.
You need either
1. have an EP that can masquade itself as being on "ext interface2" (and 
port forward) or...

2.  Set ProxyForNat=0
[Proxy]
ProxyForNat=0
and port forward  TCP port 1720 and the UDP RTP Range of  EP2  (usually 
50000 - 50999)  or...

3. Port forward TCP 1720 (to receive calls) and proxy the media.  or..

4. Use PacPhone or GnuGk NatAware IP Phone and proxy media (no port 
forwardings required).

This is the current range of choices.

You have no choice, media cannot penetrate the NAT to the gk without it 
being forwarded to the gk. Rules of NAT sorry. If the two parties involved 
in the call are outside the NAT on public IP's then media is NOT proxied.
