Add an Ethernet Layer 2 WAN Interface
You can specify any of the gateway’s Ethernet ports as a WAN interface or LAN interface. In
other words, the GE WAN (ETHWAN) interface may be used as a LAN interface, and any of
LAN1, LAN2, LAN3 and LAN 4 may be used as a WAN interface. Only one of the Ethernet
interfaces may be selected as a WAN interface. All of the other Ethernet interfaces may be use
as LAN interfaces.
1. In the left hand menu pane, click Advanced Setup.
2. Under Advanced Setup, click Layer2 Interface then ETH Interface, then click the Add
button.
3. Select the Ethernet port for the WAN interface.
Normally you would select ETHWAN, the GigE Ethernet port, though one of the LAN ports
could be selected as well.
4. Click Apply/Save to add the appropriate WAN service.
WAN Service
Use the WAN Service page to create a PPPoE, IPoE or Bridging Interface.
