[Users] openser behind provider nat

[Daniel-Constantin Mierla]

Hello,

you need to do port forwarding of the fastweb.it NAT box. Otherwise the 
outside world cannot reach your milkfish box. So, port 5060 have to be 
routed there as well as media ports (you have to configure 
rtpptoxy/mediaproxy to youse a defined range of ports).

Then you have to set OpenSER to add rport parameter to each sent 
request, so downstream proxies will know that they have to send back the 
reply to source_ip:port of the request.

This does not guaratee that will work, but should be the first steps.

Cheers,
Daniel
