At the bottom of the left pane, click the Server tab.
In the left pane, select the Site you want to modify.
In the right pane, click the Advanced tab.
Select the Max connections from same IP check box and enter a number. If the box is clear a user can create an unlimited number of concurrent connections to the site from the same IP address. (or according to the limits defined at the User or User Settings level).
Click Apply.

Start the Administrator Interface and connect to the Server.
At the bottom of the left pane, click the Server tab.
Select the User or User Setting Level you want to configure. You may have to expand a User Setting Level to see the user you want.

Select the Max connections from same IP check box and enter the maximum times you wish that User account or users in that User Setting level to be able to simultaneously connect to the site from the same IP address.
