This looks interesting.

When does nginx see the packet, before the firewall or after the 
firewall passes it through?

Employing this concept each unique domain name is the element used to 
target the jails private ip address.

Would need a server clause for each port number/domain name targeting 
each jail.

This would work for port 21, 22, 23, 25
