ProSafe Quad WAN Gigabit Firewall FR538G Reference Manual
Firewall Protection and Content Filtering 4-27
v1.0, November 2007
Setting Block Sites (Content Filtering)
If you want to restrict internal LAN users from access to certain sites on the Internet, you can use
the firewall’s Content Filtering and Web Components filtering. By default, these features are
disabled; all requested traffic from any Web site 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 block the following Web component types: Proxy, Java,
ActiveX, and Cookies. Even sites on the Trusted Domains list will be subject to Web
Components blocking when the blocking of a particular Web component is enabled.
• Keyword Blocking (Domain Name Blocking). You can specify up to 64 words that, should
they appear in the Web site name (URL) or in a newsgroup name, will cause that site or
newsgroup to be blocked by the quad WAN gigabit firewall.
