Hi all!
Does anybody know if it's possible to run a vnet jail on a non-dedicated
interface? I have the Lucas book on jails. In it he says that for vnet you
need to pick a dedicated interface, remove all networking IP configuration
and only bring it up. Afterwards you set up jib and whatnot.

All works well if I use a dedicated secondary interface (let's call it
em1). If I use em0 however I cannot ping the jail.

I would like to have a host with that has a single network interface which
is used for both normal networking stuff as well as having the vnet jail
run on it.

Maybe I could create some sort of virtual interface and run vnet on it?

Any ideas here? Thanks in advance!

Arsenij
