The network-layer access control function mainly controls the network layer and transport layer. It is a firewall function. NSFOCUS WAF incorporates this function to enable users to configure network-layer access controls on WAF. This function is available only when NSFOCUS WAF is deployed in in-path or out-of-path mode, but unavailable when the device is in reverse proxy or mirroring mode. Network-layer access control is the first step to protection by NSFOCUS WAF. This means that NSFOCUS WAF matches packets against the network-layer access control policy prior to any other policies.<\/p>\n\n\n\n

To configure network-layer access control settings on NSFOCUS WAF, follow these steps:<\/p>\n\n\n\n

1. Enable Network-Layer Access Control.<\/p>\n\n\n\n

The Policy Enable-Disable module controls whether to enable or disable Network-Layer Access Control, TCP Flood Protection, ARP Spoofing Protection, ADS Collaboration, Transparent Transmission Protection and Reuse of TCP Sequence Number of Client. To make a specific policy take effect, you must first enable this policy.<\/p>\n\n\n\n

Choose Security Management<\/strong> > Network-Layer Protection<\/strong> > Policy Enable-Disable<\/strong> and click \"Red in the Operation <\/strong>column.<\/p>\n\n\n\n

<\/p>\n\n\n

2. Configure Network-Layer Access Control.<\/p>\n\n\n\n

Choose Security Management<\/strong> > Network-Layer Protection<\/strong> > Network-Layer Access<\/strong> Control<\/strong> and click Create<\/strong>.<\/p>\n\n\n

<\/p>\n\n\n\n

Note: If Action<\/strong> is set to Block<\/strong> or Forward<\/strong>, this policy must be configured on a WAN interface. If Action<\/strong> is set to Accept<\/strong>, this policy must be configured on both a WAN interface and a LAN interface.<\/p>\n\n\n\n

Network-layer access control logs can be viewed under Logs & Reports<\/strong> > Security Protection Logs<\/strong> > Network-Layer Access Control Logs<\/strong>.<\/p>\n\n\n
