Set up NAT as you otherwise would using the "real" interface and IP as the
external network. There are several different methods for doing this, most of
which are discussed and mentioned in the handbook. I use ipfw+natd since
that's what I'm most familiar with, but pf may be a better option if you're
just getting started.
Since your "internal" network doesn't have (or need) a real network interface,
use the loopback interface (lo0). Create an alias in the 127.0.0.0/8 network
for each jail. You should of course reserve 127.0.0.1 as the "real" localhost
Set up the jails as you normally would, using the 127.x.x.x IP's you allocated
above. See the jail(8) manpage to get started. There are other howtos and
guides out there that might give more background and examples, but the
manpage has always been adequate fo my (modest) needs. You might also want to
look at the sysutils/ezjail port. See also
Decide how you are going to allocate ports and/or proxy/share commonly used
ports. For http and https (80 and 443), consider running Apache with
mod_proxy and virtualhosts.
Should get you started at least...
