That's what I recommend:

- use 2 sockets, one for communication with internal nodes, one for 
external clients
- in your Kamailio config check the direction of every message: i->e or 
e->i (for requests and responses). Depending on the direction set the 
proper IP when calling manage_rtpproxy and force the send socket:
