Provided all clients are inside your perimeter and not having another NAT in
front of them, you can safely use SER without NAT. Just make sure you
specify:
listen=xxx where xxx is the private of your FreeBSD box.
Note that it will not communicate well with outside world in this
configuration. If you need that, than yes, your clients will be detected as
NATed and you have to use the public IP interface for SER.

Subject: [Serusers] NAT + Clients directly connected to SER
Using ser 0.8.14 from cvs, I have a question regarding the example
nathelper.cfg file. The file is in sip_router/etc/nathelper.cfg
# !! Nathelper
# Special handling for NATed clients; ....
I'd like to understand if clients are considered NATed in my
configuration. I have ser running on the NAT box itself (FreeBSD
4.10-Stable). There is one public address, and several
private subnets.
SER running on this box is the sip proxy for all clients on the
private subnets.
In this topology, would the UA's on the private subnets be considered
"NATed clients" and thus pass the nat_uac_test("3") test in this
nathelper.cfg file? Or does this test only apply when NAT exists
between SER and the clients?
Thanks,
MikeC
