ProSafe 802.11g Wireless VPN Firewall FVG318 Reference Manual
Certain commonly used web components can also be blocked for increased security. Some of these components can be used by malicious websites to infect computers that access them. For example:
•Proxy. A proxy server 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. Enabling this feature 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.
•Active X. Similar to Java applets, ActiveX controls are installed on Windows computers 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.
