I've created a loopback IP lo0 of 127.0.0.2 and want to assign it to a qjail created jail. The jail also has a routable IP 192.168.1.20 on em0 to reach the Internet, but I don't want 127.0.0.2 to do that. But when I use
qjail create -n em0 testjail 18.104.22.168,127.0.0.2of course it adds 127.0.0.2 to em0 and also to lo0. It doesn't allow a -n em0 <ip> -n lo0 <ip> and gives a syntax error.
