This chapter describes how to configure a FortiBridge unit to provide fail open 
protection for a FortiGate unit operating in transparent mode. This chapter also 
describes some commonly required FortiBridge operating procedures such as 
recovering from a fail open event, manually switching between FortiBridge 
operating modes and backing up and restoring the FortiBridge configuration.

The procedures in this chapter assume that you have connected the FortiBridge 
unit to your network and completed its basic configuration as described in

connections from Internal network to the Internet.

•

Virus scanning of HTTP, FTP, POP3, SMTP, and IMAP traffic,

•

Web filtering of HTTP traffic,

Spam filtering of POP3, SMTP, and IMAP traffic.

Note: The information in this chapter can be applied to any standalone FortiGate 
transparent mode network configuration. These procedures can also be applied to a 
FortiBridge unit providing fail open protection for a FortiGate HA cluster operating in 
transparent mode.
