Deleting a filter set

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.

A sample IP filter set

This section contains the settings for a filter set called Basic Firewall, which is part of the Netopia R9100’s factory configuration.

Basic Firewall blocks undesirable traffic originating from the WAN (in most cases, the Internet), but passes all traffic originating from the LAN. It follows the conservative “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 forwarded to the LAN.
