[Serusers] Running SER Server behind NAT

[Alan]

Is it possible to run SER SIP server behind a NAT? If so, what type of
configuration changes am i looking at? My current scenario is as
follows.


Internet <-----> Pix (12.x.x.x translates to 10.x.x.x) <----> SIP Server

Requests to and from the internet have a static NAT translation rule
in a PIX firewall. Traffic flows from the outside global IP to an inside
NAT'ed IP (non-routable) and vice versa. The SIP server's interface is
configured with a non-routable IP addresss (10.x.x.x) for example. My
problem is related to the message header and the ACK has a record
route with the 10.x.x.x in it. Please help.
