By default, Tableau Server does not consider the client web browser IP address when it creates or redeems tickets. To change this, you need to do two things: specify an IP address using the client_ip parameter in the POST request that obtains the ticket, and follow the steps below to configure Tableau Server to enforce client IP address matching.
Open a command window and change directories to the location of Tableau Server's bin directory. The default location is C:\Program Files (x86)\Tableau\Tableau Server\7.0\bin
Open a command prompt as an administrator and type the following command:
tabadmin set wgserver.extended_trusted_ip_checking true
Then type the following command:
tabadmin configure
Finally, restart the server by typing the following:
tabadmin restart
