To use Branch Gateway as an endpoint device for WAN, you must install a WAN media module and connect the WAN line to a port on the media module. When you connect a WAN line to the media module, Branch Gateway serves as an router for the WAN line.

You can also use the fixed ETH WAN Fast Ethernet port as a WAN endpoint by configuring the port interface for PPPoE encapsulation (ADSL modem) or Ethernet-DHCP/static IP (cable modem).

To use Branch Gateway as a router, you must connect the external endpoint device to the ETH WAN port on the Branch Gateway front panel using a standard network cable.
