User Guide
Ethernet tab
Use this tab to configure Ethernet ports. The two ports on the left are labeled as WAN/LAN on the FX4200, and you can set either of them to be a WAN or LAN connection.
NOTE: Only one port can be set to WAN at a time.
Status: The status of the interface (Connected, Online, Offline).
Port: The ports are numbered 1 – 4, from left to right on your router.
Use Connection: Use the dropdown to select WAN or LAN for the type of Ethernet connection you want on each of the WAN/LAN ports.
NOTE: When IP Passthrough is turned on, you cannot configure Ethernet ports as WAN. Go to Network > LAN to turn IP Passthrough off.
Maximum Transition Unit (MTU): MTU is the maximum size of data packets, including headers, that can be transmitted. You might want to adjust the MTU when traffic is being tunneled or encrypted, or if you are noticing fragmentation issues. The default (1500 bytes) is the recommended MTU for your FX4200 WAN Ethernet connection. You can enter a different value between 1280 and 1500 bytes. You can set the MTU for your LAN network on the LAN tab, and for cellular on the Cellular tab.
