Mini Router + Ubuntu issue


I’m trying to get the second ethernet port to work on a Mini Router but it doesn’t.

I have a Ubuntu 22.04.1 LTS Server installed on the CM4 and everything seems to work fine except for the second ethernet port.

This is what I get:

I tried to run the script from the Wiki, but I’m pretty sure that only works for Raspberry Pi OS.

How can I go about getting the second ethernet port to run?

Thank you!
