attempt should be blocked. Please note that the URL filter
blocks web browser (HTTP) connection attempts using port 80

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”
