Filter Configuration 

 

30-17 

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. 

 

 

 

 

 

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, and block incoming telnet, FTP and HTTP connections.
