Jails and loopback interfaces

[Bigby Findrake]

I would recommend *not* trying to use 127.0.0.1.  You'll end up in a
situation where things are trying to access the local machine and are
getting the jail instead.

Instead, I recommend schlopping another IP address, an alias, onto the
loopback interface, just as you would with any other jail.  Use an RFC
1918 address, and, as with all jails, use a netmask of 32 bits.

Never worry about theory as long as the machinery does what it's supposed to do.
