How To - Allow users to access only selected web sites (domain) and block all othersin Version 10:Issue: How to allow users to access only selected web sites (domain) and blocks allothers.Step 1: First we need to create a Custom Web Category for the web sites (domains) wewish to allow or block for users. Open the Cyberoam GUI and navigate to Web filter >Category > Add. It allows you to create custom web categories.1. Enter web category name. Custom and default category name cannot be same.3. Select Classification3. Select QoS policy if you want to apply specific bandwidth to this web category.4. Under Domain Enter domain. Multiple domain names can be specified using comma e.g. cyberoam.com,bbc.com.5. Under Keyword Enter keyword. Multiple keywords can be specified using comma e.g. cyberoam,bbc.Note: Domains and Keywords can be added at the time of creation of category or laterwhenever required.Please refer the below given screen shot for more detail.
Step 2: Create a Web Filter Policy and allow/add this Custom Web Category.In the Cyberoam GUI, navigate to:1. Web filter > Policy > Add page allows you to create custom Web Filter Policy. Enter policy name. Duplicate names are not allowed.2. Select “Deny All” Template based on which you want to create new policy because we only wish to allow our Custom Web Category. After creation you can always customize the category restrictions according to the requirement. Select: Allow All – Allows access to all the categories except the specified categories. Deny All– Allows denies access to all the categories except the specified categories.3. Enter policy description.4. To apply HTTPS Based Categorization, you need to select action “Allow or Deny” for HTTPS while adding that custom web category in Web Filter Policy.5. Enable Reporting: If “Unchecked”, it would bypass reporting for this Internet access policy. Internet usage reports will not include access details of all the users to whom this policy will be applied. “Check” Enable Reporting to include access details of all the users in Internet usage reports to whom this policy is applied.
7. Click on Add button to add the custom web category. Select the Custom Web Category created for allowed websites and select the Strategy as ‘Allow’ in both HTTP and HTTPS action and select the Schedule as ‘All the Time’. Click on Add to add this Web Category and Click on “OK” button to save this Web Filter Policy.8. Similarly, we can add more category by clicking ‘Add’ button as shown in the below given screen shot.9. We can apply this policy to User, Group or in Firewall Rule. This would allow users to access only two websites which are specified in the Custom Web Category.Note: When we select the Policy Type as DENY ALL template in Web Filter Policy, itwould only allow the HTTP based traffic, which means it would only allow traffic whichis running on port 80. So if there are application which requires login (running onHTTPS), the Deny policy would not allow you to login with when you select deny alltemplate in Web Filter Policy. For Example, if we include the hotmail.com in the InternetAccess Policy with the Deny template, it would allow you to open the hotmail.comwebsite but it would not allow you to login to the hotmail.com as it is running on secureport (HTTPS). To allow secure web site in IAP, we need to create a Web Filter Policy with the Policy Type as “Allow All” template. In the allow policy type, we need to deny all the Web Categories except the categories we wish to allow. Please, find attached snapshot for more detail as below:
