Is it possible to run SER SIP server behind a NAT? If

Internet <-----> Pix (12.x.x.x translates to 10.x.x.x) <----> SIP Server
We have been running ser 0.8.99-dev19 (sparc/openbsd) for more than
a year on NAT; our solution required ser to run on the NAT border
router so that it could service the public net interfaces and the
internal NAT'ed interfaces. We use rtpproxy on the same box. I have
not actively watched the lists for any developments involving running
it on a host only on a private ip space. I don't know of a ser port
to run on the Pix. All external UAs so far have been on public
ip addresses; we haven't yet dealt with the issue of external UAs
behind NAT (perhaps a STUN solution would work, or a VPN where
feasible).
