P782M G.SHDSL Bridge Chapter 6 Filter Set Configuration This chapter shows you how to create and apply filters. 6.1 About Filtering Your Prestige uses filters to decide whether or not to allow passage of a data packet and/or to make a call. There are two types of filter applications: da ta filtering and call filtering.
P782M G.SHDSL Bridge Call Filtering Data Filtering Outgoi ng Packet Drop packet Built-in default Call Filters User-defined Call Filt ers (if appli cabl e) Initi ate c all if line no t up Active Data S.
P782M G.SHDSL Bridge Start Fetch First Filter Set Fetch First Filter Rule Active? Execute Filter Rule Fetch Next Filter Rule Next filter Rule Available? Fetch Next Filter Set Next Filter Set Available.
P782M G.SHDSL Bridge For incoming packets, your Prestige ap plies data filters only. Packets are p rocessed depending on whether a match is found. The following section s describe how to configure filter sets. 6.2 Configuring a Filter Set To configure a filter set, follow the steps sh own next.
P782M G.SHDSL Bridge Figure 6-4 Menu 21.1 — Filter Rules Summary 6.2.1 Filter Rules Summary Menus The following tables brief ly describe the abbreviations used in menus 21.1 and 21.2 . Table 6-1 Abbreviations Used in the Filter Rules Summary Menu FIELD DESCRIPTION # The filter rule number: 1 to 6.
P782M G.SHDSL Bridge Table 6-2 Rule Abbreviations Used FILTER TYPE DESCRIPTION GEN Off Offset Len Length 6.3 Generic Filter Rule The purpose of generic rules is to allow you to filter non-IP packets. For generic rules, the Prestige treats a packet as a byte stream as oppos ed to an IP packet.
P782M G.SHDSL Bridge Table 6-3 Menu 21.5.1 — Generic Filter Rule Fie l ds FIELD DESCRIPTION EXA MPLE Filter # This is the filter se t, filter rule coordinates, for instance, 2, 3 refers to the second filter set and the third rule of that set. 5,1 Filter Type This field may not be changed.
P782M G.SHDSL Bridge 6.4 Filter Configuration Example Let us look at a sample filter. See the supporting disk for more sample filters. Step 1. Enter 21 from the main menu to op en Menu 21 — Filter Set Configuration . Step 2. Enter the index of the filter set you want to configure (in this case 3) .
P782M G.SHDSL Bridge This setting logs all packets that match these rule parameters. Select Forward here so that the packet will be forwarded if the action is matched. Select Drop here so that the packet will be dropped if the action is not matched. There are no more rules to check in this filter set.
P782M G.SHDSL Bridge M = N means an action can be taken immediately. The action is to drop the packet ( m = D ) if the action is matched and to forward the packet immediately ( n = F ) i f the action is not matched no matter whether there are more rules to be checked (there are not in this example).
P782M G.SHDSL Bridge 6.5.1 Ethernet T raffic 6.5.2 Ethernet T raffic You seldom need to filter Ethernet tr affic; 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 num ber(s) of the filter set(s) that you want to apply as appropriate.
