When I add the ExternalIP to the Main section, calls inside the LAN are
ok, but I cannot then place calls to any unregistered endpoints outside
the LAN.
I am on a dynamic ADSL so I also added the ExternalIsDynamic=1 but that
also doesn't work.
I get a no route to destination error on my endpoints inside when I try
calling out.

I think you need to add your public IP to the main section like this:
[Gatekeeper::Main]
Fortytwo=42
Name=OfficeGk
TimeToLive=300
ExternalIP=x.x.x.x

Subject: Calling through two gnugks
Hi All,
I have two separate gnugks each receiving calls from the internet and passing to the catchall correctly now (many thanks Jan for the pointer).
Endpoint 1 <-----> gnugk1 <-----> internet <-----> gnugk2 <-----> Endpoint 2

public endpoint
I can call in from a public endpoint outside of each network and calls are fine too by using the domain name or the ext@domain syntax.
I can call from endpoints on each network to the public IP fine too.
Problem:
======
When I place a call from an endpoint on one network to an endpoint on the other network using the H323 url, the call connects but I cannot see or hear the other side.
What is making it difficult is that I cannot be in two places at the same time. I have tried connecting the two networks via VPN and then the call works flawlessly, but that's defeating the objective and is getting me really confused.
I assumed it may have something to do with the RTP ports used at each of the endpoints and there is a port mismatch if I use endpoints from different vendors.
I don't want the gnugks to be neighbors.
My gnugks are set exactly the same at each end except for the network addresses. My firewalls are the same as well as the port forwards.
I tried with PVX at each end, but I do not get audio or video. I also tried with Mirial but no success.
I'll try running a Wireshark trace on each gnugk interface to see what is happening and post further later.
Here is my config:

If anyone can spot my mistake please give me a pointer, I am losing serious sleep over this now!
