[Serusers] rtpproxy ip

[Giovanni Balasso]

Hi serusers,
after reading lots of docs and mailing lists I still have some doubts about 
nathelper+rtpproxy and the error message I usually get from it is 

rtpproxy: can't bind to the IPv4 port 35000: Cannot assign requested address

what is the correct way to start rtpproxy? do I have to provide nat and public 
ip?

In the following situation: machine behind nat with private IP, running ser 
and reachable from the outside via port forwarding on router's public ip 
(forwarding port 5060 for ser and ports 35000-.... for rtpproxy range, both 
udp/tcp), can I use rtpproxy? how should i start it?
(in the above situation ser registration from the outside works!)

thanks in advance
