Chapter 30 Filter Configuration

LAN traffic filter sets may be useful to block certain packets, reduce traffic and prevent 
security breaches. Go to menu 3.1 (shown next) 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 Prestige and output filter sets filter outgoing traffic from the Prestige. For PPPoE 
encapsulation, you have the additional option of specifying remote node call filter sets.

Figure 161   Filtering LAN Traffic

Go to menu 11.5 (shown below – note that call filter sets are only present for PPPoE 
encapsulation) and enter the number(s) of the filter set(s) as appropriate. You can cascade up 
to four filter sets by entering their numbers separated by commas. The Prestige already has 
filters to prevent NetBIOS traffic from triggering calls.
