That sounds pretty strange. The main FIB utilization is in routing area and has nothing to do with jails at all (a router/firewall don't need jails). (not that I'm fine with FIB concept at all, but unfortunately that's routing industry standard concept, and removing FIBs will make FreeBSD lacking behind competitors here as it was before 6.x) -- WBR, @nuclight
