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 is checked to see if any
keywords are present in URLs accessed to determine if the connection attempt should be
blocked. Note that the URL filter blocks web browser (HTTP) connection attempts using
port 80 only.
For example, the URL http://www.abc.com/abcde.html would be dropped since the keyword
“abcde” occurs in the URL.
Domains Filtering: Checks the domain name in URLs accessed against your list of
domains to block or allow. If it matches, the URL request is sent (Trusted) or dropped
(Forbidden). The checking procedure is:
1. Check the domain in the URL to determine if it is in the trusted list. If yes, the connection
attempt is sent to the remote web server.
2. If not, it is checked with the forbidden list. If present, the connection attempt is dropped.
3. If the packet matches neither of the above, it is sent to the remote web server.
4. Please be note that the completed URL, “www” + domain name shall be specified. For
example to block traffic to www.google.com.au
, enter “www.google” or
“www.google.com”
