Figure 179   Menu 21.1.6.1 Sample Filter Rules Summary

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.

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.
