4.2.2 URL Blocking
"URL Blocking" function can let you define blocking or allowing rules for incoming and outgoing Web
request packets. With defined rules, router can control the Web requests containing the complete URL,
partial domain name, or pre-defined keywords. For example, one can filter out or allow only the Web
requests based on domain input suffixes like .com or .org or keywords like “bct” or “mpe”.
An URL blocking rule should specify the URL, partial domain name, or included keywords in the Web
requests from and to the router and also the destination service port. Besides, a certain time schedule can
be applied to activate the URL Blocking rules during pre-defined time interval(s).
The router will logs and displays the disallowed web accessing requests that matched the defined URL
blocking rule in the black-list or in the exclusion of the white-list.
When you choose "Allow all to pass except those match the following rules" for the "URL Blocking Rule
List", you are setting the defined URL blocking rules to belong to the black list. The packets, listed in the
rule list, will be blocked if one pattern in the requests matches to one rule. Other Web requests can pass
through the router. In contrast, when you choose "Deny all to pass except those match the following rules"
for the "URL Blocking Rule List", you are setting the defined packet filtering rules to belong to the white list.
The Web requests, listed in the rule, will be allowed if one pattern in the requests matches to one rule.
Other Web requests will be blocked.
