Just a clarification.  When I say it is sending the ACK to the wrong 
port I am refering to this part of the message:  ACK 
sip:201 at 63.64.65.66:5060 (which is build from Contact Header details).
..not this part:  U 63.64.65.66:5060 -> 63.64.65.66:5060

Would taking the approach of tossing all the rewrites into a separate routing block and calling it from the ACK, CANCEL, BYE, and INVITE blocks be just heading down the wrong path?
