Chapter 4: Configuration
Domains Filtering: This function checks the domain name 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). 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, check if it is listed in the forbidden list, and if present then the connection
attempt is 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 domain only should be specified, not the full URL. For
example to block traffic to
www.sex.com, enter “sex” or “sex.com” instead of
“www.sex.com”. In the example below, the URL request for
www.billion.com.tw will be
sent to the remote web server because it is listed in the trusted list, whilst the URL
request for
www.sex or www.sex.com will be dropped, because billion.com is in the
forbidden list.
