If you review the current asterisk 12 sample pjsip config for extension 6002 (viewable here: http://svnview.digium.com/svn/asterisk/branches/12/configs/pjsip.conf.sample), you will find it contains the correct settings for an endpoint behind NAT. Specifically note that you need rewrite_contact enabled so that the contact address is rewritten to match the inbound SIP registration, and also with rtp_symmetric enabled to do the same thing for RTP.
Also be aware that you will have less problems by omitting the transport= line from the endpoint configuration altogether. It's generally not required to define that the endpoint is restricted to using a specific transport, and doing so interferes with the automatic transport selection, possibly including the symmetric SIP operation.
