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.
