[OpenSIPS-Users] media server behind nat

[Stefano Pisani]

There are a problem in the network configuration.
Opensips has only one network card, in this way it cound only use one IP 
but it actually has two IPs (one external and one interna).
You need to enable a second network card with a public IP (in the DMZ)  
and use mhomed=1 in configuration to change IP in SIP header according 
to interface used.

Or you can use (if available and working properly) the SIP ALG in you 
firewall instead of advertising_address.

The third option is to create DNAT (with different port) also for media 
server so all server are on public IP.

You can't mix public and private IP as you done using a single network card.
