Earl,
Thanks for your reply.
Firstly, my ADSL routers _are_ registered with dyndns addresses and my
office.domain.co.za and home.domain.co.za records point to the
respective office and home dyndns addresses correctly. That is how I can
call from an external public IP to either office or home network and the
calls are fine.
The call is definitely going to the right place when I call out from my
office to my home, I can see it in Etherape running on the office
gatekeeper machine. I call home.domain.co.za or 1234@xxxxxxxxxxxxxxxxx
and the call is hitting the gnugk on the far side ans is going to the
dyndns address of the far side router.
Note: I do not call the LAN IP of the far side gnugk, I call to it's
publically accessible IP (DNS record pointing to the dyndns address -
trust me this works!) the way I would call if my external endpoint were
on a public IP.
The problem when I have the VPN up, is that the office gatekeeper is
getting to the right address on the home gatekeeper but then the checks
for NAT run, and since the VPN is in place, connects the call via the
VPN. So audio and video go through fine. I can again see this happening
in Etherape on the office gatekeeper.
But, when I have the VPN down or disconnected (as in most normal
circumstances) and I try calling again via the internet to the other
side, the call is still going to the right place and is being answered
as expected, but I get _no audio and video_. Now this is where the NAT
stuff should kick in as it does in the call from the public IP. But
again, my public IP is not behind a NAT, so I am wondering if my NAT
configuration is correct.
The moment I add ExternalIP=office.domain.co.za to the Main section,
even the calls between internal endpoints at the office fail with the no
route to destination message.
What is strange is that calls from a public endpoint outside either
network to endpoints inside the network go throught fine. So that means
that it is proxying the calls correctly at each respective gnugk.
Now when Endpoint -GK-GK-Endpoint calls are made, it is not working
correctly for me.
As I mentioned before, I do not want the two GnuGk's to be registered
with each other, kinda like cellphones on different networks must be
able to call each other.
I have done port forwarding as per my previous posting as well as put
the respective gnugk's in the DMZ of each router. Do you think I should
do both port forwarding and DMZ together? Maybe this is my problem.
Maybe I should also be using Stun to check for NAT.
I'll keep trying and posting.

Mike,
I have been following your thread and do not understand why you are having
problems with ExternalIP in the Main section. I would think this is
necessary
for ADSL modem + router to work correctly.
Would you please try the following experiment:
register with some dynamic DNS service. First check if your router has a
built-in dynDNS possibility, and which one(s). If it does, use that one.
Then insert in the main section, for example (here an imaginary one)
[Gatekeeper::Main]
other entries ....
ExternalIP=my-address.dynDNS.com (or whatever dyndns service)
ExternalIsDynamic=0 (since dynDNS address never changes)
ping your dynDNS address to make sure it is working correctly
if not, reboot router. When working
then try GnuGK and EPs and see what happens and tell us.

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
