Url Filter - Billion 800VGT User Manual

URL Filter

URL (Uniform Resource Locator – e.g. an address in the form of
http://www.example.com) filter rules allow you to prevent users on your network from accessing particular
websites by their URL. There are no pre-defined URL filter rules; you can add filter rules to meet your
requirements.
Enable/Disable: To enable or disable the URL Filter feature.
Block Mode: A list of the URL filter rule time modes from which you can choose. The default is set to
Always On.
Disabled: No action will be performed by the Block Mode.
Always On: Action is enabled. URL filter rules will be monitoring and checking at all hours of
the day.
TimeSlot1 ~ TimeSlot16: these are user-defined time periods. You may specify the time
period during which the URL filter rules apply, i.e. during working hours. For setup and details,
refer to Time Schedule section.
Keywords Filtering: Allows blocking by specific keywords within a particular URL rather than having to
specify a complete URL (e.g. to block any image called "advertisement.gif"). When enabled, your
specified keywords list will be checked to see if any keywords are present in URLs accessed to determine
if the connection attempt should be blocked. Please note that the URL filter blocks web browser (HTTP)
connection attempts using port 80 only.
example, if the URL is http://www.abc.com/abcde.html, it will be dropped if the keyword "abcde"
For
occurs in the URL.
Domains Filtering: This function checks the whole URL (not the IP address) in URLs accessed against
your list of domains to block or allow. If it is matched, the URL request will be sent (Trusted) or dropped
(Forbidden). For this function to be activated, both check-boxes must be checked. Here is the
checking procedure:
1. The router checks the domain in the URL to determine if it is in the trusted list. If it is, the
connection attempt is sent to correct the remote web server.
2. If not, the router checks if the domain is listed in the forbidden list. If it is, then
the connection attempt will be dropped.
