EW200 Industrial Cellular Gateway 261 5.2.2 URL Blocking The "URL Blocking" function lets you define blocking or allowing rules for incoming and outgoing web request packets. With defined rules, the gateway 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 gateway and also the destination service port. A time schedule can be applied to activate the URL Blocking rules during pre-defined time interval(s). The gateway will log and display 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 blacklist. 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 gateway. 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. URL Blocking Rule with Blacklist When the administrator of the gateway wants to block web requests with specific patterns, he/she can use the "URL Blocking" function to block specific web requests by defining the blacklist as shown in the diagram. When the administrator wants to allow only web requests with some dedicated patterns to go through the gateway, he/she can also use the "URL Blocking" function by defining the white list to meet the requirement. As shown in the diagram, enable the URL blocking function and create the first rule to deny the Web requests with "sex" or "sexygirl" patterns and the other to deny web requests with "playboy" pattern to go through the gateway. The system will block the web requests with "sex", "sexygirl" or "playboy" patterns to pass through the gateway. EW200 Industrial Cellular Gateway 262 URL Blocking Setting Go to Security > Firewall > URL Blocking Tab. In the "URL Blocking" page, there are three configuration windows. They are "Configuration", "URL Blocking Rule List", and "URL Blocking Rule Configuration." The "Configuration" window lets you activate the URL blocking function and specify blacklisting or whitelisting packets as defined in the "URL Blocking Rule List"
