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.
