Configuring Web Content Filtering

If you want to restrict internal LAN users from access to certain types of information and
objects on the Internet, use the STM's content filtering and Web objects filtering. With the
exception of the Web content categories that are mentioned in
Settings on page 85, all requested traffic from any website is allowed. You can specify a
message such as "Blocked by NETGEAR" that is displayed onscreen if a user attempts to
access a blocked site (see the Notification Settings section that is described at the bottom of
Table 34 on page 112). Several types of Web content blocking are available:
• File extension blocking. You can block files based on their extension. Such files can
include executable files, audio and video files, and compressed files.
• Web object blocking. You can block the following Web objects: embedded objects
(ActiveX, Java, Flash), proxies, and cookies; and you can disable Java scripts. However,
websites that are on the whitelist (see
never subject to Web object blocking.
• Web category blocking. You can block entire Web categories because their content is
unwanted, offensive, or not relevant, or simply to reduce traffic.
Note: You can bypass any type of Web blocking for trusted domains by
adding the exact matching domain names to the trusted host list
(see Specifying Trusted Hosts
on the trusted host list is allowed for PCs in the groups for which file
extension, object, or category blocking, or a combination of these
types of Web blocking has been enabled.
Note: You can bypass any type of Web blocking for trusted URLs by
adding the URLs to the whitelist (see
on page 116). Access to the URLs on the whitelist is allowed for PCs
in the groups for which file extension, object, or category blocking, or
a combination of these types of Web blocking has been enabled.
