Hello,

> Im trying to configure RTP proxy for the following scenario.

> I have opensips in the border server between my public ipaddress and my
> internal. So that ETH0 has public IP and eth1 has private.

> I set mhomed=1 so that packets are forwarded correctly and the call does
> connect.

> First of all, is this possible with rtpproxy and opensips? I know
> Mediaproxy is not able to bind like that.

> Opensips Config looks like this.
