Справочное Руководство для Netopia r6100

Note: If you delete a filter set, all of the filters it contains are deleted as well. To reuse any of these filters in 
another set, before deleting the current filter set you’ll have to note their configuration and then recreate them.

To delete a filter set, select Delete IP Filter Set in the IP Filter Sets screen to display a list of filter sets.

Select a filter set from the list and press Return to delete it. Press Escape to exit the list without deleting the 
filter set.

This section contains the settings for a filter set called Basic Firewall, which is par t of the Netopia R6000 
Series’s factor y configuration.

Basic Firewall blocks undesirable traffic originating from the WAN (in most cases, the Internet), but for wards all 
traffic originating from the LAN. It follows the conser vative “that which is not expressly permitted is prohibited” 
approach: unless an incoming packet expressly matches one of the constituent input filters, it will not be 
for warded to the LAN.
