The communication between a remote access server and a central server to authenticate and authorize dial-in users is done using RADIUS. It then grants them access to the required system or service. ## Configuring RADIUS server settings - Go to **Settings -> Authentication -> Radius Server Settings** - Enter the server's IP Address in the **Server IP** field. - Next, enter the Authentication Port number of the server. - Enter the **Server Secret** that has been configured in the RADIUS Server. - Select the required protocol from the drop down. - Click the radio button to set the number of times the Authentication process has to be reiterated. - Click **Save** and the RADIUS server settings will be updated.
