Hi Dave,

So you cloned lo1, is the IP of the error proned jail an alias address on t=
he lo1 interface or do any interface reside on the subnet 192.168.0.0/24

here is my lo1 interface that my ezjail's use. One alias for each jail.=20

lo1: flags=3D8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
        options=3D600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>
        inet 172.16.1.2 netmask 0xffffffff
        inet 172.16.1.3 netmask 0xffffffff
        inet 172.16.1.4 netmask 0xffffffff
        inet 172.16.1.5 netmask 0xffffffff
        inet 172.16.1.6 netmask 0xffffffff
        inet 172.16.1.7 netmask 0xffffffff
        inet 172.16.1.8 netmask 0xffffffff
        inet 172.16.1.9 netmask 0xffffffff
        inet 172.16.1.10 netmask 0xffff0000
        nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
