Whitelist

Whitelist

IP addresses in the whitelist will not be added to the blacklist statically or dynamically. An entry in the whitelist is represented by a source VPN and a source IP address, and must be manually configured.

If valid service packets sent from some devices are similar to IP sweeping attack or port scanning attack packets, you can add these devices to the whitelist so that packets sent from the devices will not be discarded by the firewall.

Functions of Whitelist

If you add the VPN or IP address of a host to the whitelist, the firewall does not check packets sent from the host for IP sweeping or port scanning attack, and does not add the IP address of the host to the blacklist.

Whitelist Features Supported by the Device

After receiving a packet, the device checks whether the packet is sent from an IP address in the whitelist. If the packet is sent from an IP address in the whitelist, the device does not check the packet for IP sweeping or port scanning attack, or add the IP address to the blacklist. However, the device still performs other security checks, such as ACL-based packet filtering, ASPF, and traffic statistics and monitoring, to ensure network security.

You can set an aging time for whitelist entries.

You can export whitelist entries to a file or import entries to a whitelist from a file.
