I don't know were are you, but do you really think that a Kamailio 
server with rtpProxy server behind a NAT ADSL router with dynamic IP, 
it's for doing business ? I don't think so.

Talking about you question, the answer is, YES, it's possible to let 
that config run having the kamailio and the rtpproxy behind a NAT ADSL 
router with dynamic IP, BUT it's a pain in the ass to let it work OK.
The easier way to do it is to have at least a FIXED IP and put the ADSL 
router to work as a "modem" and having the IP directly on the server, so 
you will, at least, have no problem with port forwarding, broken SIP-ALG 
implementation on the router (I don't know any decent ADSL router with a 
working one), timeout NAT tables on the router or any other of the 2000 
million problems you could have having NAT in the middle of ..

Best Regards.
