Configuring FortiBridge probes
To monitor a FortiGate unit for failure, you configure the FortiBridge unit to send probe packets through the FortiGate unit. Using probe packets, the FortiBridge unit can confirm that the FortiGate unit can process ICMP (ping), HTTP, FTP, POP3, SMTP, and IMAP traffic. Until you configure probes, the FortiBridge unit cannot detect if the FortiGate unit has failed.
