No worries there I just think it's an awesome tool. We used plain old
jails before, and we even went through the "service jail" path once,
but EzJail is a lot more than just lightweight easy-to-use jailing.

Actually you can replicate it easily. Assign a number of IPs to any
interface but that the interface has a default route. It will always
use the "primary" or default IP on the other end. You can probably see
this effect even on a private network provided all the aliases route
through the same gateway. You will not be able to see this effect
using aliases on the loopback AFAIK.

It doesn't matter, it's a very basic network issue with aliases in
FreeBSD, Linux and other OSs. Look here:

I would like to know how people deal with this on FBSD
