Routing a network through specific interface ip alias

[catfish]

I don’t think it’s possible with incus managed network:

Which network interface does incusbr0 bind?

Just curious, and I can’t find any documents about it. Instances can use it to connect to internet, so it must use a nic to send packets. If a pc has more than one nic connect to internet, then which one will incusbr0 chooses? Can we manually config incusbr0 to use specific one?

I think you should create an unmanaged bridge using a vlan pointing to one of the public IP, then attach containers to it.
