Packet flow: FortiGates with NP6 processors – packets in an offloaded session

The first packet of a session determines if the session can be offloaded. As long as there is no proxy-based UTM/NGFW, if your FortiGate includes NP6 processors, most sessions can be offloaded to them. After the first packet, subsequent packets in an offloaded session skip routing, UTM/NGFW, and kernel processors and are just forwarded out the egress interface by the NP6 processor. As well, security measures such as DoS policies, ACL, and so on are accelerated by the NP6 processor.
