Description
This article describes how to disable Reverse Path Forwarding (RPF) per interface.
Solution
RPF is a mechanism that protects FortiGate and the network from IP spoofing attacks.
By default, RPF is enabled on all interfaces.
Disable it by enabling asymmetric route on the specific VDOM but if the requirement is only for specific interface.
Use the commands below to achieve it.
# config system interface
edit <interface>
set src-check disable
end
