+network
+=======
+
+Add or remove interfaces to existing jails.
+
+You can only add an interface once to a jail, with two exceptions.
+
+1. For classic jails, you can add an interface as many times as you want, but each time with a different IP. All this does is add the IP as another alias on that interface.
+
+2. For VNET jails, if the `-v|--vlan` switch is given along with a numerical VLAN ID, Bastille will add the VLAN ID to the jail as a vnetX.X interface, depending on which interface is specified.
+
+Bridges and VNET interfaces can be added to VNET jails, no matter if they were created with `-V` or `-B`.
