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. 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, check if it is listed in the forbidden list. If yes, then the connection attempt will be
dropped.
3. If the packet does not match either of the above two items, 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"
In the example below, the URL request for
because it is listed in the trusted list, whilst the URL request for
will be dropped, because
www.abc.com
www.google is in the forbidden list.
will be sent to the remote web server
www.google
