Hi there,
It's my understanding that the chroot's (jails) should run on different
IP addresses to that of your base system.
For instance, let's say you have three addresses:
192.168.0.10
192.168.0.11
192.168.0.12
192.168.0.10 would be that of your base machine and all it's services,
which you should make sure are bound to just that address, and none of
the others. The same would apply for your chroots. Their services
should also all be running on a seperate dedicated IP address.
Cheers,
Marc
