If not, the only alternative remaining is to move jail IP to > 192.168.2.xx/24 (which I would rather not do). The IP should only be brought up and down if there's an interface mentioned in the jail config. If there's only an IP address, then the jail will be restricted to that IP address without changing any interfaces. I assume your jail configuration has either an "interface" parameter, or an IP address designation like "re1|192.168.2.1"? Just remove that part and you should be good. Along the same lines, if you're not actually setting the interface, you don't need to worry about a subnet mask - the jail itself doesn't use that. - Jamie
