Description

It would seem that there is an upstream bug with wireguard icmp and path discovery (?) : https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=ee576c47db60

All my issues were resolved by setting the MSS field to 1420 (which enables an mss clamp of 1380) on my assigned wireguard interfaces.
