23.7.1 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 Configuration
Filter Rules
M = N means an action can be taken immediately.
The action is to drop the packet (m = D) if the
action is matched and to forward the packet
immediately (n = F) if the action is not matched no
matter whether there are more rules to be
checked (there aren't in this example).
Enter Filter Rule Number (1-6) to Configure: 1

Table 23-5 Filter Sets Table
