Microcloud init help (selecting different network to initialize on)

I have 2 nics in my servers.
the first one has a /28 address
the second one is an internal network with a /24 that is not routeable.

I try to specify the ip but still get an underlay error message that only /16 or /24’s are supported.
are there any command line options for init to make it listen or use the internal network first?

This is a limitation of the fan overlay network.

See FanNetworking - Ubuntu Wiki

We plan to add ovn support in the future which will have more options.
