Hi list,

I have a questions related the following network configuration:

UA (private IP)-------NAT(public IP)-----Internet-------(public
IP)NAT-----(private IP)OpenSBC-----(private IP)SER

The NAT box before OpenSBC has open the 5060 sip and rtp port.
As you can see I have clients behind a NAT box triyng to get access to the
SIP proxy (SER), OpenSBC is in the middle acting as B2BUA to rtp proxing if
is needed.
In this scenario the UA client can register normally on the SIP registar
(behind OpenSBC), but the SIP REGISTER message from OpenSBC to SIP
registar has in the contact header the original private IP address of the
client. The fact is the client can call but it cannot be called because the
private address.

Is it normal this behaviour? Can I configure OpenSBC to replace the contact
header with the OpenSBC IP address? This way all the calls to the UA pass
through OpenSBC given it has control over the NAT.

Thanks very much,
Antonio.
