[OpenSIPS-Users] NATed REGISTERs are failing

We're not getting that far.

The REGISTER comes in, OpenSIPs sends a 100 (sl_send_reply), then a 401 (www_challenge).  Both the 100 and the 401 are being sent to the private ( instead of the public.

Do you mean that the 200 OK for the REGISTER is sent by OpenSIPS to a private IP instead of the public IP of the NAT router?
That is not possible. Responses are always sent to the real received IP.
