Using Ethernet devices in a WAN

The EX15 device has two Ethernet devices, named 1/PoE and 2/WAN. You can use these Ethernet interfaces as a WAN when connecting to the Internet, through a device such as a cable modem:

By default, the 2/WAN Ethernet device is configured as a WAN, named WAN, with both DHCP and NAT enabled and using the External firewall zone. This means you should be able to connect to the Internet by connecting the 2/WAN Ethernet port to another device that already has an internet connection.

The 1/PoE device is configured either as a LAN interface, named LAN, or, for a wireless-enabled EX15W device, as part of a bridge named LAN that is used by the LAN interface, which uses the Internal firewall zone.
