DGFV338 ProSafe Wireless ADSL Modem VPN Firewall Router Reference Manual
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.
–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 option filters out cookies from being created by a website.
Note: Many websites require that cookies be accepted in order for the site to be 
accessed properly. Blocking cookies may cause many websites to not
function properly.
•Keyword (and domain name) Blocking – You can specify up to 32 words that, should they appear in the Web site name (URL) or in a newsgroup name, will cause the site or newsgroup to be blocked by the wireless firewall.
You can apply the keywords to one or more groups in the Apply Keyword Blocking to: fields. Requests from the PCs in the groups for which keyword blocking has been enabled will be blocked. Blocking does not occur for the PCs that are in the groups for which keyword blocking has not been enabled.
If you enter a domain name in the Trusted Domains box, keyword filtering will be bypassed. For example, if you entered www.netgear.com, keyword filtering will be bypassed for this domain; however, Web Components filtering still applies.
Keyword application examples:
•If the keyword “XXX” is specified, the URL http://www.badstuff.com/xxx.html is blocked, as is the newsgroup alt.pictures.XXX.
•If the keyword “.com” is specified, only Web sites with other domain suffixes (such as .edu or
.gov) can be viewed.
•If you wish to block all Internet browsing access, enter the keyword “.”.
