9 Filter Configuration

About Filtering

Your Prestige uses filters to decide whether or not to allow passage of a data packet and/or to make a call over the ISDN line. There are two types of filters involved: incoming data filters and outgoing data filters. Data filters screen the data to determine if the packet should be allowed to pass.

Figure 9-1 Outgoing packet filtering Process

For incoming packets, your Prestige applies data filters only. Packets are processed depending upon whether a match is made. Your Prestige allows you to customize the filter sets that you wish to use. The following sections describe how to configure your Prestige filter sets.
