* - 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, opt, lan1, ext-wlan,
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.
* - Each name consists of letters (interface type), followed by a number (x). For most interfaces, x is limited by
the maximum number of the type of interface. For WLAN interfaces, the first number identifies the slot and
the second number identifies the individual interface.
** - Cellular interfaces can be added to the WAN zone or no zone.
