Hi,

Operating system is FreeBSD 10.0 64 Bit

I have installed ezjail from ports and properly configured a jail with
its own static and dedicated IP address. Everything works good, it's
just that I have an application which requires to talk to another one
via RPC on IP 127.0.0.1, and I have noticed the jail does not have a
lo0 interface or localhost 127.0.0.1 IP address.

This is bad because the application has no choice but to bind to the
public IP address assigned to the jail, and it's not safe.

How can I add a lo0 interface with IP 127.0.0.1 to a jail?

Thanks in advance.
