I moved this question from the developers list.
I have put a small list of NAT traversal strategies and whether they are
supported and require media proxying by GNUGK if on the outside of the NAT.
Calls from behind NAT.
Registered supported proxy.
unregistered not supported. Note: Patch pending to add
support (proxy).
Calls to NATed EPs
Registered not supported returns reason "User unreachable"
GnuGK aware EP supported proxy (using GNUGK Nat feature)
GnuGK on NAT supported proxy (only to GNUGK outside NAT)
NAT Traversal Strategies (require help from NAT box or external helper)
Port forward supported proxy.
Port forward Masq. supported No proxy. (using the external IP of
the NAT)
STUN supported No proxy (not work with
some NATs)
UPnP supported No proxy (Require
compatible NAT box)
Calls between EP's behind same NAT
Registered supported No proxy
Note: You will need to enable support for NATed EPs in the settings.
I hope this helps and clears a few things up.

Hello,
I have 2 questions:
1.Is there possibility for called endpoint to be behind the NAT ?
2.Is there possibility for called endpoint to be behind the same NAT
as the GK ?
I've tried with routed mode gnugk -r -tt but when i make call
gatekeeper is trying to open rtp proxy channel
