I use no tools for creating/controlling jails. I have a /etc/jail.conf :

exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
exec.clean;
mount.devfs;
exec.consolelog = "/var/log/jail.$name.log";

testjail {
        host.hostname = "testjail";
        ip4.addr = 79.x.x.213;
        ip4.addr += 10.4.3.6;
        ip6.addr = 2a00:x:x:x::3;

        path = "/opt/jails/testjail";
        exec.prestart = "/root/jail_prestart.sh $path";
        allow.raw_sockets = 1; # For debugging
}

I start a stop it with 'service jail start|stop testjail'

I tried to define the 10.4.3.6 alias with a 255.255.255.0 netmask, but
it makes no difference
