Chapter 13 Interfaces
Relationships Between Interfaces
In the ZyWALL, 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.
Table 58 Relationships Between Different Types of Interfaces

trunk
* - You cannot set up a PPP 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 PPP interface on top of it.
