9.4 Applying a Filter and Factory Defaults
This section shows you where to apply the filter(s) after you design it (them). The ExpWave already has filters to
prevent NetBIOS traffic from triggering calls.
9.4.1 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 below) and enter 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 entering their numbers separated
by commas, e.g., 3, 4, 6, 11. Input filter sets filter incoming traffic to the ExpWave and Output filter sets filter outgoing
traffic from the ExpWave.
