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 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.

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.
