ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3

Manage Content Filtering

To restrict internal LAN users from access to certain sites on the Internet, you can use the

content filtering and web component blocking features of the VPN firewall.

The following sections provide information about how to manage content filtering:

• Content Filtering Overview

• Enable Content Filtering and Select Web Components

• Manage Keywords and Domain Names That Must Be Blocked

• Manage Domain Names That You Trust

• Manage Keyword Blocking for LAN Groups

Content Filtering Overview

By default, content filtering and web component blocking 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 see a “Blocked by NETGEAR” message.

Note: Content filtering is supported for IPv4 users and groups only.

The VPN firewall provides several types of blocking:

• Web component blocking. Even trusted sites are subject to web component blocking

when the blocking of a particular web component is enabled. You can block the following

web component types:

- 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 feature blocks Java applets from being downloaded.

- ActiveX. Similar to Java applets, ActiveX controls are installed on a Windows

computer running Internet Explorer. A malicious ActiveX control can be used to

compromise or infect computers. Enabling this feature blocks ActiveX applets from

being downloaded.

- Cookies. Cookies are used to store session information by websites that usually

require login. However, several websites use cookies to store tracking information

and browsing habits. Enabling this feature blocks cookies from being created by a

website.
