See my post yesterday to Alan on running SER behind a NAT, the same (at least) applies. You may also look at advertised_address and advertised_port. g-)

I'm using nathelper with SER. Here's a quickie diagram of my setup:
[SIP ATA] <-------------> [SER] <------------------> [Asterisk] 10.0.201.5 eth1 - 10.0.201.7 eth0 - <public_ip1> eth0 - <public_ip0>
I'm using the basic nathelper example configuration, except for one modification. I removed the call to t_relay and replaced it with:
t_relay_to("<public_ip1>", "5060");
Basically I want a SIP packet to come in to eth1 on SER server, get rewritten as needed by nathelper, then get sent out to public_ip1 on my Asterisk PBX.
This appears to be working except a tcpdump on eth0 on SER shows:
14:39:08.654908 IP 10.0.201.7.5060 > <public_ip1>.5060: UDP, length 629
Obviously the packets will never get back with that source IP address. What command should I be looking at to rewrite this IP so it shows up as <public_ip0> automatically?
I'm trying to get SIP ATA's to REGISTER on my Asterisk box but proxy through SER ... (and eventually make use of the rtp proxy).
Can post more info if requested, I am new to SER. :-)
