Jails within different networks ... ?

[Snoop]

Hi there, I've a doubt!
I have 3 jails within the host xxx.xxx.26.224 configured in this way
(below) and everything works well.
What if I want to enable another jail but I don't want to assign to that
my next available public ip address xxx.xxx.26.228/24 but I want this
jail to have a private ip address like 172.16.1.2/27?
Is that possible or it's a delirium?
I don't want to waste my public ip address for a jail which I want to
have a network configured but not to be publicly visible.

Many thanks in advance.
