For a firewall filter to work, you must assign it to an interface. Use the Firewall Filters Quick Configuration pages to assign IPv4 and IPv6 filters to interfaces. Using these pages you can select a firewall filter to evaluate packets that are received or transmitted on a specific interface.
When assigning firewall filters to interfaces, remember that you can assign only one input and one output firewall filter to each interface. However, you can assign the same filter to multiple interfaces.
Figure 20 shows the Firewall Filters Quick Configuration page that displays the Services Router interfaces available for filter assignment and the status of existing filter assignments.
