[OpenSIPS-Users] mediaproxy behavior

[Jorge Ortea]

Hi all,

This is right Saul, my purpose is that Mediaproxy opens ports on private IP, and the firewall redirects from public IP to private IP on same ports. This could let me have voip platform (SER + Asterisk) on private network and to need only one public IP.

Thanks.
Regards.
