Example FortiBridge application FortiBridge operating principles The FortiGate unit acts as an extra layer of protection for your internal network. While it is operating, the FortiGate unit protects the internal network from threats originating on the Internet. All users on the internal network connect through the FortiGate unit to the Internet. This also means that if a failure or other interruption caused the FortiGate unit to stop functioning, users on the internal network would not be a

Bypass mode operation FortiBridge operating principles Bypass mode operation When the FortiBridge unit operates in bypass mode, the FortiBridge INT 1 and EXT 1 interfaces are directly connected. All traffic between the internal and external network segments flows, whether or not the FortiGate unit is operating normally. Because the INT 1 and EXT 1 interfaces are directly connected, you cannot use Telnet or SSH to connect to the FortiBridge CLI. Instead you must use a console connection. T

FortiBridge operating principles Example FortiGate HA cluster FortiBridge application Example FortiGate HA cluster FortiBridge application A FortiBridge unit can provide fail open protection for a FortiGate HA cluster operating in transparent mode in much the same way as for a standalone FortiGate unit. To provide fail open protection for an HA cluster, connect the FortiBridge unit to the switches that connect the internal and external interfaces of the cluster. Use the following steps to co
