URL Filter
URL (Uniform Resource Locator – e.g. an address in the form of http://www.abcde.com or 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 URL Filter feature.
Block Mode: A list of the modes that you can choose to check the URL filter rules. 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.
For example , if the URL is http://www.abc.com/abcde.html , it will be dropped as the keyword “abcde” 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, then the
connection attempt is sent to correct the remote web server.
