STEP 2 To edit the setting of a physical port, click Edit.
After you click Edit, the Ethernet Configuration - Add/Edit window opens.
STEP 3 Enter the following information:
• Name: The name of the physical port.
• Port Type: The physical port type, such as WAN , LAN, or DMZ.

Access mode for a WAN or DMZ port. By default, all ports are set to Access
mode.
- Access: All data going into and out of the Access port is untagged.
Access mode is recommended if the port is connected to a single end-
user device which is VLAN unaware.
- Trunk: All data going into and out of the Trunk port is tagged. Untagged
data coming into the port is not forwarded, except for the DEFAULT VLAN,
which is untagged. Trunk mode is recommended if the port is connected
to a VLAN-aware switch or router.
• Port: Click On to enable the port, or click Off to disable it. By default, all ports
are enabled.
• VLAN: You can assign the physical port to VLANs.

VLAN list and click the right arrows >> to add it to the VLAN list.
- To release the port from a VLAN, choose a VLAN from the VLAN list and
click the left arrows <<.
NOTE A LAN port can be assigned to multiple VLANs, but an Access LAN
port can only be assigned to one VLAN. A DMZ port must be assigned
to a DMZ network.
NOTE To create new VLANs, click Create VLAN. For more information about
how to configure the VLANs, see Configuring the VLAN, page 118.
