I oversaw that you device is not symmetric: it requests the answers send back to port 5060 but it sends it request from another port. Your device should put add the rport paramter to its via. Alternativly you can force rport adding at your SER (please consult the docs how to do this).

As you can see from your own network dump, the NAT devices sends back an ICMP port unreachable (3:3). This means the 200 OK send from SER back to your device never reaches the device. Please fix your NAT device.

Here's the scenario: As of now, I can only get users to register with my SER if I don't use database authentication. These users must also have a static IP address to register.
I am now trying to get a client to register with SER from behind a NAT. I am using a STUN server address to help with the NAT situation. When I do this I get a 483 message.
From looking at similar posts, the problem is
usually caused by setting uri=="some.domain.com" I don't have this configuration; in ser.cfg I have the following:
alias="my.domain.com"
if(uri==myself)
Also, I am running ser-0.8.12 if that makes any difference.
Does anybody know why I am getting 483 error messages?
Any help is always appreciated.
