[Serusers] using ser to involve nat

[WangZhenzhong]

Hi every body
I am using ser to solve the nat problem, 
In my environment:  invite A-->SER-->B


1. SER receive the invite message REQA from A(invite B)
2. SER judge the use B, if the B is in public network, will fix nat in the REQA message
    if judge the B is in private network , will not fix anything

and I want to know, how to judge the B's network, when the SER receive the INVITE from A?
Is there any examle code used in ser.cfg


thank you very much
