Blocking Internet Sites (Content Filtering)

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. 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.
Several types of blocking are available:
• Web Components blocking. You can filter the following Web Component types: Proxy, Java,
ActiveX, and Cookies. For example, by enabling Java filtering, "Java" files will be blocked.
Certain commonly used web components can be blocked for increased security. Some of these
components are can be used by malicious Websites to infect computers that access them.
– 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.
– ActiveX. Similar to Java applets, ActiveX controls install on a Windows computer
running Internet Explorer. A malicious ActiveX control can be used to compromise or
infect computers. Enabling this setting blocks ActiveX applets from being downloaded.
