Wireguard on AWS - Out-Of-Order Packets

If you setup a Wireguard on AWS, the tunnel MTU is set inherited from the AWS primary NIC, which is set to 9000 and Wireguard will set the tunnel MTU to 8921.

On your Wireguard server, set the MTU size of the AWS primary interface to 1500 to resolve the issue.
