Configuring a Standard IP Access List for Packet Filtering
This section describes how to configure a standard IP access list so that only authorized traffic is allowed on
the cable interface.
This procedure assumes a basic knowledge of how access lists use an IP address and bitmask to determine
the range of IP addresses that are allowed access. For full details on configuring access lists, see the
documents listed in the Additional References, on page 35.
