AFAIK rtpproxy only support 1 WAN und 1LAN interface.

This is IMO a good idea, because it would bypass issue #1.

But AFAIK the nathelper module only supports one rtpproxy.

force_socket is only to force a certain local socket to use when using 
UDP connections between nathelper and rtpproxy.

to overcome issue 1 and 2 you can try setup a second openser which 
communicates with the seconds rtpproxy over a different rtpproxy_sock.

nevertheless it would be a hack :-)
