you should not need that. Kamailio should do record routing, advertising 
the public IP, so the signaling from the other side is sent to Route 
headers, not to Contact address.

Use:

listen=udp:_internal_ip_:5060 advertise _external_ip_:5060

Asterisk has support for external IP, so it can advertise that IP in SDP 
and the media will go directly to the asterisk. Makes no sense to make a 
user space forwarding with rtpproxy.

Cheers,
Daniel
