I am trying to get Kamilio to work in the following configuration and after days of googling and configuration attempts, I have come here for help.

Two servers, both sharing the same database. Server1, Server2. Both servers are behind a NAT (AWS).

If I set the DNS to return both IP addresses for the domain on the A record, everything works, all is well.

If I set the DNS to return values based on latency and the Calling Client gets Server1's IP Address but the Receiving Client is registered to Server2, the call fails from a timeout. I can see the attempt to go through at the packet level and a 'non-local' socket message as well.

If the DNS returns Server2's IP Address and the Receiving Client is registered to Server2, the call completes.

I have tried numerous variations of the various 'path' and 'registrar' options with any joy. I tried making one of the servers the central registrar as well. I am not entirely sure I ever set everything correctly, but I have tried numerous combinations.

Any thoughts would be appreciated, I only ask this as I think I have exhausted my own list of things to try.

Thanks.
