LAN or WAN Port LEDs Not On
If either the LAN LEDs or WAN LEDs do not light when the Ethernet connection is made, check
the following:
• Make sure that the Ethernet cable connections are secure at the UTM and at the hub, router, or
workstation.
• Make sure that power is turned on to the connected hub, router, or workstation.
• Be sure you are using the correct cables:
When connecting the UTM’s WAN ports to one or two devices that provide the Internet
connections, use the cables that are supplied with the devices. These cables could be a
standard straight-through Ethernet cables or an Ethernet crossover cables.
Troubleshooting the Web Management Interface
If you are unable to access the UTM’s Web Management Interface from a PC on your local
network, check the following:
• Check the Ethernet connection between the PC and the UTM as described in the previous
section (“LAN or WAN Port LEDs Not On”).
• Make sure your PC’s IP address is on the same subnet as the UTM. If you are using the
recommended addressing scheme, your PC’s address should be in the range of 192.168.1.2 to
192.168.1.254.
Note: If your PC’s IP address is shown as 169.254.x.x:
Windows and MacOS generate and assign an IP address if the computer
cannot reach a DHCP server. These auto-generated addresses are in the range
of 169.254.x.x. If your IP address is in this range, check the connection from
the PC to the UTM and reboot your PC.
