[OpenSIPS-Users] NAT and ACK (private IP/domain)

[Bogdan-Andrei Iancu]

HI Julian,

The ACK will be routed based on Route + RURI info. Route hdr made the 
ACK to get to .201 and the RURI will continue to .71. The RURI from ACK 
is taken from the Contact hdr of the 200 OK reply.

AMybe posting the whole stuff (INVITE+200 OK + ACK) will make things easier.

Regards,
Bogdan
