Using Ethernet devices in a WAN

The TX54 device has four Ethernet devices, named ETH1, ETH2, ETH3, and ETH4. 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 WAN/ETH1 Ethernet device is configured as a WAN, named WAN1, 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 WAN/ETH1 Ethernet port to another device that already has an internet connection.

The ETH2, ETH3, and ETH4 devices are by default configured as part of a bridge named LAN1 that is used by the LAN1 interface, which uses the Internal firewall zone. If desired, you can assign these Ethernet devices to a WAN.
