30.7 Applying Filters and Factory Defaults
This section shows you where to apply the filter(s) after you design it (them). Sets of factory
default filter rules have been configured in menu 21 (but have not been applied) to filter
traffic.
30.7.1 Ethernet Traffic
You seldom need to filter Ethernet traffic; however, the filter sets may be useful to block
certain packets, reduce traffic and prevent security breaches. Go to menu 3.1 (shown next) and
type the number(s) of the filter set(s) that you want to apply as appropriate. You can choose up
to four filter sets (from twelve) by typing their numbers separated by commas, for example, 3,
4, 6, 11. The factory default filter set,
NetBIOS_LAN , is inserted in the protocol filters field
under Input Filter Sets in menu 3.1 in order to prevent local NetBIOS messages from
triggering calls to the DNS server.
