3.4.3.5.1 Packet Filtering
Packet filtering function enables you to configure your router to check specified internal/external user (IP address) from Internet access, or you can disable specific service request (Port number) to /from Internet. This configuration program allows you to set up different filter rules up to 6 for different users based on their IP addresses or their network Port number. The relationship among all filters is “or” operation, which means the device checks these different filter rules one by one, stating from the first rule. As long as one of the rules is satisfied, the specified action will be taken.
