Filter Types and SUA

Conceptually, there are two categories of filter rules:

device

and

protocol

. The Generic filter rules belong to the

device category; they act on the raw data from/to LAN and WAN. The IP and IPX filter rules belong to the

protocol category; they act on the IP and IPX packets.
