Jail can only have one IP address (in addition > to loopback addresses). Do you mean this just for jail.conf configuration/usage? If so, from all I’ve read and tried, that makes complete sense, and makes me sad as it prevents me from using the slickness of jail.conf(1) and jail_set(2) - not yet :) -- However, to be very clear for the list archive, jails can most definately have many IP addresses, (since between FreeBSD 7 and 8 I believe?), including loopback, (which is just an IP address like any other), For example, # ifconfig em0 inet alias 10.10.10.10/32 # ifconfig em1 inet alias 10.10.10.11/32 # ifconfig lo0 inet alias 127.0.0.11/32 # ifconfig em0 inet6 alias 2:2:2:2::10 prefixlen 64 # jail -c path=/some/place host.hostname=myjail ip4.addr=“10.10.10.10,10.10.10.11,127.0.0.11" ip6.addr="2:2:2:2::10" command=/bin/sh /etc/rc Best, .ikehelp
