MTU #6037

Closed Scotty714 closed 2 months ago

Scotty714 commented 2 months ago

The MTU of my network is 1472. Wireguard sets the default MTU of 1420. As far as i am aware the overhead for Wireguard is 60 bits for IPv4, so i need to change the default to 1412. I can do this manually - but every new connection defaults to 1420. Is there a variable i could add into the docker config to change this?

many thanks

@Scotty714 Do you mean setting MTU for all myst* interfaces, including myst0 ?

ip link set dev myst0 mtu 1420

Scotty714 commented 2 months ago

yeah - i can do that but then any new connections created default to 1420

@Scotty714

I've added a command line argument for setting Wireguard MTU: --wireguard.mtu=1400

Example of use: myst --wireguard.mtu=1400 service

Its available in the latest build docker pull mysteriumnetwork/myst-snapshots:1.29.19-1snapshot-20240426T1308-ee113ab7-alpine
