Chapter 5 Configuring the Router’s Security
Advanced Filtering
Advanced filtering is designed to allow comprehensive control over the firewall’s behavior. Specific input and output rules can be defined, the order of logically similar sets of rules controlled, and distinctions made between rules that apply to Internet and local network devices.
To access, select Advanced Filtering from any Security screen. The “Advanced Filtering” screen appears.
Two sets of rules can be configured: input rules and output rules. Each set of rules
comprises three subsets: initial rules, network devices rules, and final rules. These subsets determine the sequence by which the rules will be applied. Following is a description of the set ordering for inbound and outbound packets.
