Description
This article describes that some FortiGate models include bypass interfaces that provide fail-open support.
Scope
FortiGate models with bypass ports.
Solution
See the v6.x of the Hardware Acceleration for information about FortiGate models that support bypass interfaces.
For example:
FortiGate 800D fast path architecture
FortiGate 2500E fast path architecture
Some models that come with a bypass interface will have the syntax bypass in the model name, for example: FortiGate 80F Bypass
This feature enables fail-open when there is a hardware failure.
For example, in FortiGate 80F Bypass, WAN1 and Port1 have bypass features. When the unit encounters a hardware failure, the connection on those 2 ports becomes fail-open and continues to provide network connectivity.
