[Users] registering E60/N80 behind NAT to openser

[Markus Monka]

Hi everybody,

does someone has Nokia device (E60|N80) connected to an openser
in an (symmetric) nated enviroment?

I use nathelper and mediaproxy and it is the error/mistake a get.

While using fix_nated_contact or fix_contact, the device discarded the
200 ok response and displays an error. 

Nokia says, that rewriting the contact is a NAT Travesal trick, no
feature 
and the Stack denied the response.

Any Ideas how to solve this problem?

Best Regards,
Markus
