[Serusers] NAT Handling - SER behind a router

[TZieleniewski]

Thank you for your answer!

Could you give me some more hints how to enable local user agent 
together with far-end NAT working together.
One thing I should do is probalby to record route all messages so that 
the whole signalling goes through SER which knows
the local IP adresses of local UA and those of the NAT'ed ones.

I have an cisco router which has an SIP handling support, so perhaps  it 
will be enought  just to  enable nathelper pinging 
to sustain the NAT bindings with nated UAs and make strict port 
forwarding only to SER port 5060 and rest (fixing Contact and SDP) will 
be done by the router.
Do You think that this might work.

Cheers
Tomasz
