This section provides instructions for troubleshooting connection issues when using
a FortiGate in Transparent mode.
1. Use FortiExplorer if you can't connect tot he FortiGate GUI or CLI
If you can't connect to the FortiGate GUI or CLI, you may be able to connect using
FortiExplorer. See your FortiGate unit's QuickStart Guide for details.
2. Check for equipment issues.
Verify that all network equipment is powered on and operating as expected. Refer to the
QuickStart Guide for information about connecting your FortiGate to the network and about
the information provided by the FortiGate unit LED indicators.
3. Check the physical network connections.
Check the cables used for all physical connections between the PC, the FortiGate unit, and
your ISP-supplied equipment to ensure that they are fully connected and do not appear
damaged. Also check the Unit Operation dashboard widget, which indicates the connection
status of FortiGate network interfaces (System > Dashboard > Status).
4. Verify that you can connect to the management IP address of the
FortiGate unit from the Internal network.
From the internal network, attempt to ping the management IP address. If you cannot
connect to the internal interface, verify the IP configuration of the PC and make sure the
cables are connected and all switches and other devices on the network are powered on
and operating. Go to the next step when you can connect to the internal interface.
5. Verify that you can communicate from the FortiGate unit to the Internet.
Access the FortiGate CLI and use the execute ping command to ping an address or
domain name on the Internet. You can also use the execute traceroute command to
troubleshoot connectivity to the Internet.
