Web Filter: This feature provides options allowing you to filter any
potential risk contained in some web technologies by
individually checking
“Allow” or “Deny”.
Web proxy is a server your device will connect to when you
access any web site. Setting web proxy can speed up
access time but also can create other potential security
issues. For example, if you configure the Wireless Security
Router to block access to 216.115.102.76, which is the IP
address of www.yahoo.com, it will fail. This is because your
PC will connect to web proxy server instead of connecting to
Yahoo
’s IP address.
Java & Active X are programming languages for web page.
However, some potentially harmful Trojan programs and
viruses are also written in these languages. If you deny
access to either of these, you may run the risk of not having
access to certain web pages.
A cookie is a small piece of data (usually in the form of a text
file), which is stored on your PC when you visit certain web
sites. This allows the server to identify your machine at a
future date. The cookie normally contains an ID number but
can also contain other information.
Block
WAN
Request: By enabling the Block WAN Request feature, you can
prevent your network from being "pinged," or detected, by
other Internet users. The Block WAN Request feature also
reinforces your network security by hiding your network
ports. Both functions of the Block WAN Request feature
make it more difficult for outside users to work their way into
your network. This feature is enabled by default. Check this
to enable this feature.
3.10 Services
3.10.1 Virtual Server
The Virtual Server Settings application allows you to set up more than ten public
services that can be accessed by external users of the Internet, such as a Web, Email,
FTP etc. Each service is provided by a dedicated network computer (server)
configured with a fixed IP Address. Although the internal service addresses are not
directly accessible to the external user, the Wireless Security Router is able to identify
the service requested by the service port number and redirects the request to the
appropriate internal IP Address/server. To use this application, it is recommended you
use a fixed Public IP Address from your ISP. Note that your Wireless Security Router
supports only one server for each particular type.
