Assigning IPv4 and IPv6 Firewall Filters to Interfaces

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.

To assign IPv4 and IPv6 firewall filters to interfaces with Quick Configuration:

In the J-Web interface, select Configuration>Firewall Filters>Assign Firewall Filters to Interfaces.
Enter information into the Firewall Filters Quick Configuration pages, as described in Table 56.
Click one of the following buttons on the Firewall Filters Quick Configuration main page:
- To apply the configuration and stay in current the Firewall Filters Quick Configuration page, click Apply.
- To apply the configuration and return to the previous Quick Configuration page, click OK.
- To cancel your entries and return to the previous Quick Configuration page, click Cancel.
