Example, host=8.0 jail1=8.1 and jail2=8.2 But host=8.2 and jail1=9.0 will have unknown reliability. Technically there is no checks stopping someone from doing this and from the outside all will look correct, but it will fail and you may lose both the host and jail. There is a system utility called qjail that simplifies jail building. http://qjail.sourceforge.net/ Its in the ports system.
