Hello,

assuming AmneziaWG is configured manually, what would be the correct MTU? For vanilla WG these are Outer MTU - IP Header (20 for IPv4, 40 for IPv6) - UDP Header (8) - WireGuard Header (32). What does this look like with AmneziaWG?

As I understand it, no junk is attached to the actual data packets, so the MTU remains the same as with WireGuard.
