Domains Filtering:
This function checks the whole URL address but not the IP address against your list of domains
to block or allow. If it is matched, the URL request will either be sent (Trusted) or dropped (Forbidden). For this function
to be activated, both the enable and disable checkboxes of Domain Filtering 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 t he packet does not match either of the above two conditions, it is sent to the remote web server.
4. Please note that the completed URL,
“www” + domain name should be specific. e.g.: In order to block traffic to
www.google.com.au
, enter “
www.google
” or “
www.google.com
”
In the example below, the URL request for
www.abc.com
will be sent to the remote web server because it is listed in
the trusted list, whilst the URL request for
www.google
or
www.google.com
will be dropped, because
www.google
is
in the forbidden list.
Example:
Andy wishes to disable all WEB traffic except for domains listed under the trusted domains, which would prevent Bobby
from accessing other websites. Andy selects both conditions in Domain Filtering thinking that this will stop Bobby. Bobby
knows the Domain Filtering function; it ONLY disables all WEB traffic to Trusted Domains, BUT not its IP address. If
this is the situation, the Block surfing by IP address function can be helpful. Now, Andy can successfully prevent Bobby
from accessing other websites.
Restrict URL Features
: This function enhances the restrictions to your URL rules.
Block Java Applet
: This function can block Web content that includes Java Applets. It prevents someone from
damaging your system via standard HTTP protocol.
Block surfing by IP address:
A further restriction against someone who uses IP addresses as a URL to cheat
the Domains Filtering rule. Only activates if Domain Filtering is enabled.
