Hello, I also wanted to have it work, but failed and just had to patch my /etc/rc.d/jail until it's resolved. The first problem is that currently /etc/rc.d/jail creates jails using the parameterless form of jail(8). Another issue is that after the jail is created, it currently seems not possible to squeeze the "ifconfig vnet ..." in between "jail ..." and "jexec ..." -- I mean using *_exec_afterstart and *_exec_poststart in the order they are invoked now by the jail rc script. I had to invent a kind of "exec_earlypoststart" locally, and call all routines the following order: 1. /usr/sbin/jail called in the parameter-aware mode 2. _exec_earlypoststart 3. _exec_afterstart 4. _exec_poststart Then the rc.conf would look like: cloned_interfaces="$cloned_interfaces epair0" ifconfig_bridge0="addm epair0a $ifconfig_bridge0" ifconfig_epair0a="up" jail_list="$jail_list QQ" jail_QQ_flags="-l -U root vnet persist name=QQ" jail_QQ_name="QQ" jail_QQ_rootdir="/usr/jails/QQ" jail_QQ_hostname="QQ.localhost" jail_QQ_exec_earlypoststart0="ifconfig epair0b vnet QQ" jail_QQ_exec_afterstart1="ifconfig epair0b 10.1.1.1" jail_QQ_exec_afterstart2="ifconfig epair0b inet6 2001::1:1:1 prefixlen 128" jail_QQ_exec_afterstart3="ifconfig lo0 127.0.0.1" jail_QQ_exec_afterstart4="route -n add default 10.0.0.1" # bridge0 jail_QQ_exec_afterstart5="route -n add -inet6 default 2001::1" # bridge0 jail_QQ_exec_afterstart6="/bin/sh /etc/rc" Note that the "/bin/sh /etc/rc" which is the default in the current jail rc script is called here explicitly, because parameter form of jail(8) cannot run commands inside jails.
