Just don't know just what setting is needed when the Portech is behind
NAT...<br>

thank you for your answer.<br>
<br>
As I said in my previous mail, I'm using a Zyxel NBG-419 router (which
normally supports VoIP and QoS). Firewall is disabled on the Zyxel.<br>
<br>
The MV-374 only accepts IP-address, not a FQDN. Will give it another
try though...<br>
<br>
The answer from Portech-support : "use STUN".<br>
<br>
Even if the NAT rewrites the IP-address/port combination, why is it a
problem for the Portech and not for the IP-phones (Grandstream &
Snom) ? They all communicate on port 5060 --> 5064 (several
SIP-accounts)<br>
