Using Ethernet devices in a WAN

The EX50 device has two Ethernet devices, named WAN and LAN. 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 1/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 1/WAN Ethernet port to another device that already has an internet connection.

The 2/PoE+ device is configured as a LAN interface, named LAN, which uses the Internal firewall zone.
