Think I have seen it but cant say where..

You wont be able to test this from inside your network.. ie you cant try
to talk to the adsl box on port 5361 or 5362 to test while you are on your
network. You will have to dial in from somewhere else.. This may be a
reason why it doesnt seem to work.

  Also before we got adsl at work we had linux with ip-masquerading, the
same as what the cobaly cube will do for you.. When we had adsl installed
we had all sorts of troubles, ie would complain of the peer reseting the
connection on the first attempt to load a page, reload would then load it.

   It was later found out that the gateway was still the linux box which
did its masquerading and then used the adsl box which applied its nat.
This didnt work.. its something else that you might want to know about..
