Configuring Web URL Filtering
If you want to allow or block internal LAN users from access to certain sites on the Internet, use
the STM’s Web URL filtering. You can create or import a whitelist that contains domain names
and URLs that will be accepted and a blacklist with domain names and URLs that will be blocked.
The whitelist takes precedence over the blacklist.
To configure Web URL filtering:
1.
Select
Web Security
>
HTTP/HTTPS
from the menu. The HTTP/HTTPS submenu tabs
appear, with the Malware Scan screen in view.
2.
Click the
URL Filtering
submenu tab.
The URL Filtering screen displays (see
Figure 4-14 on
page 4-35
).
Web Category Lookup
URL
Enter a URL to find out if it has been categorized, and if so, in which category.
Then, click the
lookup
button. If the URL has been categorized, the category
appears next to Lookup Results.
Clear Web
Category Cache
Click
Clear Web Category Cache
to enable the STM to synchronize with the
NETGEAR server and download the most recent Web categorizations.
Note
: Synchronizing might temporarily slow down the STM’s performance
because the STM must acquire the Web categorizations remotely instead of from
its local cache.
