I found sysutils/ezjail in the ports tree to be very helpful in setting
up jails.  Just needed an up to date buildworld and it did the rest.

On my 6.0 machine it's worked like a charm.  Once you get the hang of
it, you can use the Flavours feature to cut down on post-jail configuration.

As far as I know, you do need 1 IP per jail, which is aliased off the
interface the jail is running under (check out the ifconfig_iface_alias
example in /etc/defaults/rc.conf if you've not done this before).

Hope that helps.

Cheers,
