Is forwarding the STUN ports required ? In my setup, behind a cable
modem ->  WRT54G <-> WAP54g (flashed with dd-wrt, setup as a listener
client),so I have 2 subnets internaly, both NATing, and stun gets
through without any port forwarding.

Looks like it. He's with T-Online's Speedport W502V. It connects to
traditional landlines & allows "DSL_Telephonie". The other possibility
is a transparent proxy on SIP ports to force usage of there servers,
and thus their own SIP service. Does this sound plausible ?

I'll get him to install VNC and go have a look...

Thanks for the help !
