6.9 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 rules that apply to 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. Following is a
description of the set ordering for inbound and outbound packets.
6.9a Inbound/Outbound Packets - Rule Sets
There are numerous rules automatically inserted by the firewall to provide
improved security and block harmful attacks. These pre-populated rules
displayed are required for operation on the Verizon network.
