Nope, haven't as I have various internal SIP clients that use the port 
range UDP 11000 to 11009. Therefore I cannot set up incoming NAT to only 
one internal client.

Basically I wonna allow incoming UDP traffic on ports 11000 to 11009 to 
any internal device (maybe limitating to a couple of external IP 
addresses of the VoIP providers.

Any idea? Thanks much so far and best regards, Guido
