Configuring NP7 processors

You can use the config system npu command to configure a wide range of settings for each of the NP7 processors in your FortiGate, including adjusting session accounting and session timeouts. As well you can set anomaly checking for IPv4 and IPv6 traffic.

You can also enable and adjust Host Protection Engine (HPE) settings to protect networks from DoS attacks by categorizing incoming packets based on packet rate and processing cost and applying packet shaping to packets that can cause DoS attacks.

The settings that you configure for an NP7 processor with the config system npu command apply to traffic processed by all interfaces connected to that NP7 processor. This includes the physical interfaces connected to the NP7 processor as well as all VLAN interfaces, IPsec interfaces, LAGs, and so on associated with the physical interfaces connected to the NP7 processor.

Some of the following options are only available if your FortiGate is licensed for hyperscale firewall features.
