[OpenSIPS-Users] do i need nathelper if my client keeps pinging all the time?

[Bogdan-Andrei Iancu]

Hi George,

It looks like you use the add_rcv_param() function when processing the 
REGISTER.
That is not the correct way of fixing the private registrations, but 
rather via the fix_nated_register() function :
http://www.opensips.org/html/docs/modules/1.11.x/nathelper.html#id294034

Use that function for the REGISTER requests (if coming from behind NAT) 
and before doing the save(location)
