Pass – Only the log about Pass will be recorded in Syslog.
Block – Only the log about Block will be recorded in Syslog.

Enable URL Access Control - Check the box to activate URL
Access Control. Note that the priority for URL Access Control is
higher than Restrict Web Feature. If the web content match the
setting set in URL Access Control, the router will execute the
action specified in this field and ignore the action specified under
Restrict Web Feature.
Prevent web access from IP address - Check the box to deny
any web surfing activity using IP address, such as http://202.6.3.2.
The reason for this is to prevent someone dodges the URL Access
Control. You must clear your browser cache first so that the URL
content filtering facility operates properly on a web page that you
visited before.
Action – This setting is available only when Either : URL
Access Control First or Either : Web Feature First is selected.
Pass - Allow accessing into the corresponding webpage with the
keywords listed on the box below.
Block - Restrict accessing into the corresponding webpage with
the keywords listed on the box below.
If the web pages do not match with the keyword set here, it will
be processed with reverse action.
Group/Object Selections – The Vigor router provides several
frames for users to define keywords and each frame supports
multiple keywords. The keyword could be a noun, a partial noun,
or a complete URL string. Multiple keywords within a frame are
separated by space, comma, or semicolon. In addition, the
maximal length of each frame is 32-character long. After
specifying keywords, the Vigor router will decline the connection
request to the website whose URL string matched to any
user-defined keyword. It should be noticed that the more
simplified the blocking keyword list is, the more efficiently the
Vigor router performs.
