Content Filtering (Blocking Internet Sites)

If you want to restrict internal LAN users from access to certain sites on the Internet, you can use
the VPN firewall's content filtering and Web components filtering features. By default, these
features are disabled; all requested traffic from any website is allowed. If you enable one or more
of these features and users try to access a blocked site, they will see a "Blocked by NETGEAR"
message.

Understanding the VPN Firewall's Content Filtering

The VPN firewall supports several types of content filtering:
• Web components blocking. You can block the following Web component types: Proxy, Java,
ActiveX, and cookies. Some of these components can be used by malicious websites to infect
computers that access them. Even sites on the Trusted Domains list will be subject to Web
components blocking when the blocking of a particular Web component is enabled.
– Proxy. A proxy server (or simply, proxy) allows computers to route connections to other
computers through the proxy, thus circumventing certain firewall rules. For example, if
connections to a specific IP address are blocked by a firewall rule, the requests can be
routed through a proxy that is not blocked by the rule, rendering the restriction ineffective.
Enabling this feature blocks proxy servers.
– Java. Blocks Java applets from being downloaded from pages that contain them. Java
applets are small programs embedded in Web pages that enable dynamic functionality of
the page. A malicious applet can be used to compromise or infect computers. Enabling this
setting blocks Java applets from being downloaded.
