Note: - * The format of interface names other than the Ethernet and ppp interface names is
strict. Each name consists of 2-4 letters (interface type), followed by a number (x). For
most interfaces, x is limited by the maximum number of the type of interface. For VLAN
interfaces, x is defined by the number you enter in the VLAN name field. For example,
Ethernet interface names are wan1, wan2, lan1, lan2, dmz; VLAN interfaces are vlan0,
vlan1, vlan2,...; and so on.
** - The names of virtual interfaces are derived from the interfaces on which they are
created. For example, virtual interfaces created on Ethernet interface wan1 are called
wan1:1, wan1:2, and so on. Virtual interfaces created on VLAN interface vlan2 are
called vlan2:1, vlan2:2, and so on. You cannot specify the number after the colon(:) in
the Web Configurator; it is a sequential number. You can specify the number after the
colon if you use the CLI to set up a virtual interface.
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.
