TrueNas Scale & Hetzner vSwitch

have installed TrueNas Scale on Hetzner on bare metal!

I want to enable vSwitch https://docs.hetzner.com/robot/dedicated-server/network/vswitch

I can’t set MTU to 1400

Does anyone have experience setting up Hetzner vSwitch on TrueNas or how to set MTU to 1400?

Can you not just enter the MTU in the network interface UI?

Truenas was installed on Hetzner dedicated server, after connecting kvm I was able to change mtu to 1400 which in not available from ui.

In the boot screen, I choose “1” configure network and changed mtu
