Adding a Ping Server

Adding a ping server is required for routing failover for the modem in redundant mode. A ping server confirms the connectivity to an Ethernet interface. When the Ethernet connection to the Internet goes down, the ping server will continually check the interface until it comes up. When it does come up, the FortiGate unit will switch back to the Ethernet connection and shut down the modem.

To add a ping server to an interface

1Go to System > Network > Interface.

2Choose an interface and select Edit.

3Set Ping Server to the IP address of the next hop router on the network connected to the interface.

4Select the Enable check box.

5Select OK to save the changes.

Dead gateway detection

The FortiGate unit uses dead gateway detection to ping the Ping Server IP address to make sure the FortiGate unit can connect to this IP address.

Modify dead gateway detection to control how the FortiGate unit confirms connectivity with a ping server added to an interface configuration. For information about adding a ping server to an interface, see above.

To modify the dead gateway detection settings

1Go to System > Network > Options.

2For Detection Interval, type a number in seconds to specify how often the FortiGate unit tests the connection to the ping target.

3For Fail-over Detection, type a number of times that the connection test fails before the FortiGate unit assumes the gateway is no longer functioning.

4Select Apply.
