Note: A quick reminder - You can also Block Web Browsing but Allow Intranet Traffic with IPSec.

15. Back in the Manage IP Filter Lists and Filter actions review your filters and if all are set, click on the Manage Filter Actions tab. Now we need to add a filter action that will block our designated traffic, so click Add.

10. In the IP Filter List window select one of the previously configured IP Filters, for example "HTTP, HTTPS" (configured in step #6 at the beginning of this article). If, for some reason, you did not previously configure the right IP Filter, then you can press Add and begin adding it now. When done, click Next.

11. In the Filter Action window select one of the previously configured Filter Actions, for example "Block" (configured in step #15 at the beginning of this article). Again, if you did not previously configure the right Filter Action, you can now press Add and begin adding it now. When done, click Next.

12. Notice how the IP Filter has been added.

Again, you can add any combination of IP Filters and Filter Actions you like.

Notice that you cannot change their order like in other full-featured firewalls. Even so, this configuration works perfectly as you will soon discover.

The next phase is to assign the IPSec Policy.

Assigning the IPSec Policy

1. In the same MMC console, right-click the new IPSec Policy and select Assign.

Done, you can now test the configuration by trying to surf to restricted and unrestricted websites.
