Using Filtering Rules

Filtering is a feature that allows you to control who can access a particular published resource. You can define filtering rules based on any of the following:

  • User
  • Client device name
  • Client device operating system
  • IP address
  • MAC address
  • Gateway

By default, no filtering rules exist for a published resource, therefore the resource is available to anyone who is connected to the Parallels RAS farm. Once you specify a filtering rule for a published resource, only those users/computers who satisfy the criteria will be able to use it.

To create a filtering rule, select a published resource in the Published Resources tree and click the Filtering tab. In the Select Filtering Type drop-down list, select a criteria and then define a filtering rule as described below.

Filtering by user

To allow individual users or a user group to access the published resource:

  1. Select Userin the Search Filtering Type drop down list.
  2. Select the Allow the following Users option.
  3. Click Tasks > Addand specify a user or a group in the Select Users dialog. Click OK to add a user/group to the list on the Filtering tab page.
  4. In the Default Object Type drop-down list, select whether this rule will applies to users, groups, or both.
  5. In the Browse Mode drop-down list, select the browsing mode you would like to use to connect to Active Directory or Windows.

    The options are:

    • WinNT. WinNT is faster than LDAP but does not support group nesting. Used only for backward compatibility.
    • LDAP. LDAP supports group nesting but is slow. Used only for backward compatibility.
    • Secure Identifier. This is the preferred and fastest method. It supports group nesting and renaming.

To convert users or groups specified using WinNT or LDAP, select a user entry and then click Tasks > Convert.

Filtering by client device name

To allow a specific client device or a list or client devices to access the published resource, follow these steps:

    • Import from CSV. Allows you to select a CSV file containing the list of names of client devices. The file should contain a single device name on each row. The names must be unique (no duplicates) or you will see an error message.
    • Export to CSV. Allows you to export the list of client device names to a CSV file.
    • Delete. Allows you to delete a selected client. If no client is selected in the list, the option is disabled.
