The filtering rules database gives you control over the configurable firewall rules. Rules can be filter- based on any of the following:
•Source and destination router interfaces
•IP protocols
•Direction of traffic flow
•Source and destination network/host IP address

•Source and destination port ranges (for protocols that support them), and support for port comparison operators such as less than, greater than, and equal to.
Rules can specifically allow or deny packets to flow through the router. Default actions taken when no specific rule applies can also be configured.
