DESCRIPTION
This list displays the trusted web sites already added.
Click this button when you have finished adding the host name in the
text field above.
Select a web site name from the Trusted Web Site list, and then click
this button to delete it from that list.
Sites that you want to block access to, regardless of their content
rating, can be allowed by adding them to this list. You can enter up to
32 entries.
Enter host names such as www.bad-site.com into this text field. Do not
enter the complete URL of the site – that is, do not include "http://". All
subdomains are blocked. For example, entering "bad-site.com" also
blocks "www.bad-site.com", "partner.bad-site.com", "press.bad-
site.com", etc.
This list displays the forbidden web sites already added.
Click this button when you have finished adding the host name in the
text field above.
Select a web site name from the Forbidden Web Site list, and then
click this button to delete it from that list.
Keyword Blocking allows you to block websites with URLs that
contain certain keywords in the domain name or IP address.
By default, the ZyWALL checks the URL's domain name or IP address
when performing keyword blocking.
This means that the ZyWALL checks the characters that come before
the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php,
content filtering only searches for keywords within www.zyxel.com.tw.
See the CLI reference guide to set the ZyWALL to check the full path of
the URL (the characters that come before the last slash in the URL).
Enter a keyword (up to 31 printable ASCII characters) to block. You can
also enter a numerical IP address.
This list displays the keywords already added.
Click this button when you have finished adding the key words field
above.
Select a keyword from the Keyword List, and then click this button to
delete it from that list.
Click Apply to save your changes back to the ZyWALL.
Click Reset to begin configuring this screen afresh.
