Configuring DNS Whitelist PoliciesNEW!

About this task

A DNS whitelist policy is used in conjunction with a captive portal to provide access services to wireless clients. Use the whitelist policy to create a set of allowed destination IP addresses within the captive portal. To effectively host hotspot pages on an external Web server, the IP address of the destination Web server(s) must be in the whitelist.

To configure the whitelist:

Procedure

  1. Go to Policies > Captive Portals > DNS Whitelist.
    The DNS Whitelist window opens. If any whitelist policies are configured, they appear in a list in the DNS Whitelist pane. The total number of configured whitelist policies is shown in parentheses. You can choose from the following actions:
    1. Select the sort icon adjacent to a column heading to sort the data by the heading topic. By default, the data is sorted in ascending order, as indicated by the direction of the arrow in the icon . Toggle the icon to sort the column data in descending order . The "1" indicates by which column heading topic the data is currently sorted.
    2. Select the Edit icon associated with an existing whitelist policy in the list to modify it. See step 2 for details.
    3. Select the Delete icon associated with an existing whitelist policy in the list to remove it.
    4. Select the Add icon to create a new whitelist policy.
      When you select Add, the Add Policy window opens.
      1. Configure a Name for the whitelist policy that is to be applied to the captive portal policy. Enter a policy name containing up to 32 characters.

      2. Select Add to save the new whitelist policy, then proceed to step 2.

  2. Edit or configure the Whitelist Entries parameters in the Details window as follows:
    1. Enter a numerical IP address or Hostname within the DNS Entry field.
    2. Use the Match Suffix drop-down menu to choose Yes to match any hostname or domain name as a suffix. The default setting is No.
    3. Select Add to add a new whitelist entry.
    4. If necessary, you can select the Delete icon associated with an existing whitelist entry to remove the entry from the whitelist.
  3. After you have completed configuring the settings, choose from the following actions:
    1. Select Apply to commit the configured settings.
      Note

      Note

      This does not save the settings you configured; it provides a preview of your applied settings. To undo the settings you applied, select Revert.
    2. Select Save to commit and save the configured settings.
      Note

      Note

      If you do not select Save, the settings that you configured are not saved when you move away from the configuration window.
