With standard Linux iproute2 syntax, it is possible to override the path MTU for a specific route with a command like ip route add 172.16.105.0/24 dev wg0 mtu 1432
. If this hasn’t already been done, are there any plans to expose this functionality through the VyOS CLI?
This would be useful for cases such as wireguard interfaces, where a single interface may have multiple peers with differing path MTU values. (I know I can adjust MSS for TCP traffic, but that doesn’t address non-TCP traffic, such as QUIC).
