Introduction
This chapter introduces you to the FortiBridge-1000 and FortiBridge-1000F
products that provide fail open protection for FortiGate Antivirus Firewalls
operating in transparent mode. Fail open protection keeps network traffic flowing
in the event of a FortiGate unit failure. This chapter contains the following topics:
• About FortiBridge
• About this document
• Fortinet documentation
• Customer service and technical support
About FortiBridge
The FortiBridge products are a solution for enterprise organizations to provide fail
open protection for FortiGate units deployed inline in transparent mode. The
FortiBridge products use multiple probe protocols to detect failures in the
FortiGate unit. FortiBridge zero power fail open technology means that the
FortiBridge unit also fails open if a power failure occurs.
Figure 1: FortiBridge unit
A FortiBridge unit functions as a pass-through device when a FortiGate unit or
FortiGate HA cluster operating in transparent mode fails or loses power. The
FortiBridge unit bypasses the FortiGate unit to make sure that the network can
continue processing traffic. The FortiBridge unit is not a firewall or antivirus
device. FortiGate services are not applied when the FortiBridge unit bypasses
traffic.
