Trusted Computer 

IP Address

To enable this feature, type an IP address of any one of the computers in your 

network that you want to have as a trusted computer. This allows the trusted 

computer to have full access to all features that are configured to be blocked by 

content filtering.
Leave this field blank to have no trusted computers.

Restrict Web 

Features

Select the box(es) to restrict a feature. When you download a page containing a 

restricted feature, that part of the web page will appear blank or grayed out.

ActiveX 

A tool for building dynamic and active Web pages and distributed object 

applications. When you visit an ActiveX Web site, ActiveX controls are 

downloaded to your browser, where they remain in case you visit the site again. 

Java

downloadable Web components or Internet and intranet business applications of 

all kinds.

Cookies

Web Proxy

A server that acts as an intermediary between a user and the Internet to provide 

security, administrative control, and caching service. When a proxy server is 

located on the WAN it is possible for LAN users to circumvent content filtering by 

pointing to this proxy server. 

Keyword Blocking

Enable URL 

Keyword Blocking

The NBG334W can block Web sites with URLs that contain certain keywords in 

the domain name or IP address. For example, if the keyword "bad" was enabled, 

all sites containing this keyword in the domain name or IP address will be 

blocked, e.g., URL http://www.website.com/bad.html would be blocked. Select 

this check box to enable this feature.
