16.1.2 Relationships Between Interfaces
In the Zyxel Device, interfaces are usually created on top of other interfaces. Only Ethernet interfaces
are created directly on top of the physical ports (or port groups). The relationships between interfaces
are explained in the following table.
* - You cannot set up a PPPoE/PPTP interface, virtual Ethernet interface, or virtual VLAN interface if the
underlying interface is a member of a bridge. You also cannot add an Ethernet interface or VLAN
interface to a bridge if the member interface has a virtual interface or PPPoE/PPTP interface on top of it.
