I am trying to add a virtual interface to a bare metal Ubuntu Server 20.10 installation.
I've read that in pre version 20 this wasn't possible in netplan, and that people were reverting to ifup/ifdown. But this is supposed to be possible with what I have.
I am trying to give my server a second interface so I can bind a pihole docker container to said interface.
I see in the netplan docs various interface types, and the closest one is a vlan type, but it doesn't seem that type works with untagged vlans.
In any case, I appreciate any help you can give me.
