The router has the ability to filter packets based on specific characteristics of Ethernet frames. Filters are used to specify interfaces and broad
guidelines, while rules allow very fine, protocol-specific control over packets. Generic Rules look for a particular pattern within any Ethernet frame.
These features are intended for advanced users and network professionals only, and can safely be ignored by most users.
