Following up here since it’s the only relevant post I can find …
On my Zimaboard 2 I cannot change eth1 using the UI, clicking on the 3 dots does nothing at all.
I can change eth0 using the the 3 dots although I don’t need to.
If I click on the blue Configure ports button, I can select eth1 but there’s no way to change anything that I can see so I don’t see the point of this button???
