24.5 Applying a Filter

This section shows you where to apply the filter(s) after you design it (them). The Prestige
already has filters to prevent NetBIOS traffic from triggering calls, and block incoming telnet,
FTP and HTTP connections

24.5.1 Applying LAN Filters

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
or PPTP encapsulation, you have the additional option of specifying remote node call filter
sets.

24.5.2 Applying Remote Node Filters

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.
