I have been reading over the creation of Jails on FreeBSD, and one stumbling block I have is regarding network interfaces.

Say my local router is, and the BSD box is I would like jails on

Do I just define them in rc.conf (without any other work), or do I have to set up a bridge or something like that (I see FreeNAS uses a bridge)?

I'm not particularly strong the networking side of things, so any good explanation about how the Jails share and access the network would be valuable.

Jails get ip aliases on your network interface. If the jails use the same interface as the host and are on the same subnet you don't need to do any additional routing.

If your jails do not use the same interface you would need to bridge the primary interface with the interface the Jails use.
