Chapter 11 Filter configuration
NN47922-501
Applying a Filter
This section shows you where to apply the filters after you design them. The
Business Secure Router already has filters to prevent NetBIOS traffic from
triggering calls, and block incoming Telnet, FTP and HTTP connections.
Applying LAN Filters
LAN traffic filter sets are useful to block certain packets, reduce traffic and
prevent security breaches. Go to menu 3.1 (shown next) and enter the numbers of
the filter sets that you want to apply, as appropriate. You can choose up to four
filter sets (from twelve) by entering their numbers separated by commas, for
example., 3, 4, 6, 11. Input filter sets filter incoming traffic to the Business Secure
Router and output filter sets filter outgoing traffic from the Business Secure
Router. For
PPPoE or PPTP encapsulation, you have the additional option of
specifying remote node call filter sets.

Note:
Nortel recommends that you apply filters if you do not activate
the firewall.
