Interface Properties
Interface Type Select one of the following option depending on the type of network to which the Zyxel
Device is connected or if you want to additionally manually configure some related
settings.
internal is for connecting to a local network. Other corresponding configuration options:
DHCP server and DHCP relay. The Zyxel Device automatically adds default SNAT settings for
traffic flowing from this interface to an external interface.
external is for connecting to an external network (like the Internet). The Zyxel Device
automatically adds this interface to the default WAN trunk.
For general, the rest of the screen’s options do not automatically adjust and you must
manually configure a policy route to add routing and SNAT settings for the interface.
Interface Name This field is read-only if you are editing an existing VLAN interface. Enter the number of the
VLAN interface. You can use a number from 0~4094. For example, use vlan0, vlan8, and so
on. The total number of VLANs you can configure on the Zyxel Device depends on the
model.
Zone Select the zone to which the VLAN interface belongs.
Base Port Select the Ethernet interface on which the VLAN interface runs.
VLAN ID Enter the VLAN ID. This 12-bit number uniquely identifies each VLAN. Allowed values are 1 -
4094. (0 and 4095 are reserved.)
Priority Code This is a 3-bit field within a 802.1Q VLAN tag that’s used to prioritize associated outgoing
VLAN traffic. “0” is the lowest priority level and “7” is the highest. See Table 176 on page 433.
The setting configured in Configuration > BWM overwrites the priority setting here.
