Add Trusted IP Addresses or Host Names to Tableau Server

The first step in setting up trusted authentication is to configure Tableau Server to recognize and trust requests from one or more web servers:

  1. Open a command prompt as an administrator and navigate to your Tableau Server bin directory (for example, C:\Program Files\Tableau\Tableau Server\2018.1\bin).

  2. Type the following command to stop Tableau Server:

    tabadmin stop
  3. Next, type the following command:

    tabadmin set wgserver.trusted_hosts "<trusted IP addresses or host names>" 

    In the command above, <trusted IP addresses> should be a comma-separated list of the IPv4 addresses or host names of your web server(s).

    Note:  The values you specify completely overwrite any previous setting. Therefore, you must include the full list of hosts in the set command. (You cannot amend the list of hosts by running the set command repeatedly.)

    For example:

    tabadmin set wgserver.trusted_hosts ",," 


    tabadmin set wgserver.trusted_hosts "webserv1, webserv2, webserv3" 

    The comma separated list should be in quotes, with one space after each comma.
    The web servers you specify must use static IP addresses, even if you use host names (learn more).

  4. If you have one or more proxy servers between the computer that is requesting the trusted ticket (one of those configured in Step 2, as shown in Trusted Authentication) and Tableau Server, you also need to add them as trusted gateways using the tabadmin set gateway.trusted option. See Configure a reverse proxy server for steps.

  5. Type the following command to save the changes to all the server configuration files:

    tabadmin config
  6. Finally, type the following command to start the server again:

    tabadmin start

Next, you need to configure your web server to receive tickets from Tableau Server.
