Filter Configuration 

 

8-19 

Input Filter Sets: 

Apply filters for incoming traffic. You may apply protocol or device 
filter rules. See earlier in this chapter for information on filters.  

Output Filter Sets:  Apply filters for traffic leaving the Prestige. You may apply filter rules 

for protocol or device filters. See earlier in this section for 
information on types of filters. 

Call Filter Sets: 

Apply filters to decide if a packet should be allowed to trigger a call. 

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 next) and type 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 
typing their numbers separated by commas, for example, 3, 4, 6, 11. The factory default filter set, 
NetBIOS_LAN, is inserted in the protocol filters field under Input Filter Sets in menu 3.1 in order to 
prevent local NetBIOS messages from triggering calls to the DNS server. 

Go to menu 11.5 (shown next) and type the number(s) of the filter set(s) as appropriate. You can cascade up 
to four filter sets by typing their numbers separated by commas. The factory default filter set, 
NetBIOS_WAN, is inserted in the protocol filters field under Call Filter Sets in menu 11.5 to block local 
NetBIOS traffic from triggering calls to the ISP.
