27.5 Firewall Versus Filters
Firewall configuration is discussed in the firewall chapters of this manual. Further comparisons are also made between filtering, NAT and the firewall.
27.6 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.
Note: If you do not activate the firewall, it is advisable to apply filters
27.6.1 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.
