• When you download a page containing ActiveX or Java, that part of the
web page will be blocked with an X.
• When you download a page coming from a Web Proxy, the whole web
page will be blocked.
• When you download a page containing cookies, the cookies will be
removed, but the page will not be blocked.
ActiveX is 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 is a programming language and development environment for building
downloadable Web components or Internet and intranet business applications
of all kinds.
Cookies are files stored on a computer's hard drive. Some web servers use them
to track usage and provide service based on ID.
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.
When this box is selected, the Zyxel Device will permit Java, ActiveX and
Cookies from sites on the Trusted Web Sites list to the LAN. In certain cases, it
may be desirable to allow Java, ActiveX or Cookies from sites that are known
and trusted.
These are sites that you want to allow access to, regardless of their content
rating, can be allowed by adding them to this list.

"partner.zyxel.com", "press.zyxel.com", and so on. You can also enter just a top
level domain. For example, enter "*.com" to allow all .com domains.
Use up to 127 characters (0-9a-z-). The casing does not matter. "*" can be used
as a wildcard to match any string. The entry must contain at least one "." or it
will be invalid.
