This section describes:
• Probe settings
• Enabling probes
• Verifying that probes are functioning
• Tuning the failure threshold and probe interval
Configure probe settings to control the response when a FortiBridge probe
detects that the FortiGate unit has failed. Probe settings consist of:
Table 11: Probe settings
Probe Setting Description
Action on failure Set the FortiBridge unit response when a probe detects that
the FortiGate unit has failed. The FortiBridge unit can.
• Send alertmail
• Fail open
• Send an SNMP trap
• Send a message to a syslog server
You can add up to four actions on failure. All of the
configured actions on failure occur when the FortiBridge
unit detects a failure.
Dynamic IP Configure the INT 2 and EXT 2 interfaces with dynamic
pattern probe IP addresses. The dynamic probe IP addresses
should not conflict with IP addresses on the network that
the FortiGate unit is connected to. These IP addresses are
not visible from the outside network, but they should not
conflict with IP addresses in packets passing through the
FortiBridge unit. You cannot change the dynamic IP pattern
if any probes are enabled.
FortiGate unit The serial number of the FortiGate unit that the FortiBridge
serial number unit is connected to. The serial number appears in
FortiBridge alert mail, and syslog messages to identify the
FortiGate unit.
To configure probe settings
This procedure shows how to configure the following probe settings:
• The FortiBridge unit responds to a FortiGate unit failure by failing open and by
sending an alert email, a syslog message, and an SNMP trap
• The dynamic IP pattern is 2.2.2.*
• The FortiGate unit serial number is FGT8002803923050
Note: The FortiBridge unit does not have to fail open if the FortiGate unit fails. The
FortiBridge unit can be configured just to send alerts if the FortiGate unit fails.
