Chapter 33 Filter Configuration 343

33.7.1 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.

33.7.2 Remote Node Filters

Go to menu 11.5 (shown next) and type the number(s) of the filter set(s) as appropriate. You

can cascade up to four filter sets by typing their numbers separated by commas. The factory

default filter set,

NetBIOS_WAN, is inserted in the protocol filters field under Call Filter Sets

in menu 11.5 to block local NetBIOS traffic from triggering calls to the ISP.
