Radius servers are used to authenticate clients attempting to connect to a wireless network. They are also used in conjunction with DHCP (Dynamic Host Configuration Protocol) servers to provide dynamic IP addressing to wireless clients. Radius authentication is used by most large organizations that have many users connecting via a wireless network. The reason for this is that it is much easier to manage user accounts on a centralized server than it is to maintain each individual workstation.
Although the configuration of a radius server can be somewhat complex, it does have the ability to make your life easier when it comes time to troubleshoot or manage your wireless network. A radius server can also be used for more than just wireless networks, but we will focus on its use for this application in this article.
Setting Up A Radius Server For Wireless Authentication
WPA2 Enterprise Radius Server is a RADIUS server for Windows. It provides the ability to authenticate users against Active Directory, LDAP or SQL databases, and also to provide centralized administration of security policies.
It supports all the modern authentication methods (PEAP, TTLS, EAP-TLS) as well as MSCHAPv2 with MSCHAPv2-derived user passwords.
The program has been designed with ease of use in mind and it is fully automated, allowing you to setup a working radius server in just a few minutes.
In this article, we will be configuring a Windows 2016 Server as a wireless radius server and authenticating wireless clients. The following is a step-by-step guide on how to set up a radius server for wireless authentication.
Step 1: Install the Network Policy and Access Services Role on the Domain Controller
To begin, open Server Manager and click Manage > Add Roles and Features. In the Add Roles and Features wizard, select Role-based or feature-based installation. Click Next until you reach the Select destination server page, where you should select your domain controller from the list of servers. Click Next again, then click Install to install the Network Policy and Access Services role onto your domain controller.
Step 2: Configure Your Wireless Interface
After installing NPS on your domain controller, open Server Manager > Tools > Network Policy Server management console. Right click on Policies > Properties > IPv4 tab, then click Edit Feature Settings… > General tab. In the drop down list under Interface name, choose your wireless interface from the list and click OK twice to save changes.
WPA2 Enterprise Wireless Authentication: How to Set Up Radius Server
You can setup a wireless network so that wireless connections are authenticated by a RADIUS server, also known as 802.1X authentication. This means that your users will have to provide a username and password to gain access to the network. The benefit is that you can set up a secure and centralized authentication system for your network, which will allow you to enforce security policies such as password complexity requirements and account lockouts.
This guide will show you how to configure your Windows Server 2016 domain controller as an 802.1X (RADIUS) wireless authentication server.
You can set up a Radius server to authenticate users on your wireless network. You can do this by configuring the Radius server in your Active Directory domain, or by installing a separate standalone Radius server.
A Radius server is used to authenticate clients against an existing domain controller or another RADIUS server in the network. With Windows Server 2016, you can install the Remote Access role and configure a RADIUS server as part of this role. Or, you can install and configure a standalone RADIUS server on Windows Server 2016 as well.
In this guide I will show how to install and configure a RADIUS server on Windows Server 2016.
A Radius server is a central location for collecting authentication requests from wireless clients and passing them to the authentication server. A Radius server can also be used to forward authentication requests from one server to another, such as an external RADIUS server or an internal RADIUS proxy.
Radius supports many different encryption methods for secure connections between wireless clients and servers. It also supports several methods of user authentication, including EAP-TLS (Extensible Authentication Protocol-Transport Layer Security) and PEAP (Protected Extensible Authentication Protocol).
The first step in configuring a Windows Server 2016 computer as a RADIUS server is to install the Remote Access role service on the server. This installs all of the necessary components on the computer that are required by RADIUS. You then need to configure the RADIUS client settings on your network devices so that they know where to send authentication requests.
WPA2 Enterprise Radius Server
Installing a WPA2 Enterprise Radius server on Windows 2016 Server is a very easy task, it requires only a few steps and your server will be ready to use.
The first thing you need to do is open Server Manager by right clicking on the Start Menu and selecting it from the list of options.
In the Server Manager window, click on Add Roles and Features.
Once you have clicked on Add Roles and Features, select Role-based or feature-based installation.
On the Installation Type screen select Role-based or feature-based installation and click Next.
On the Server Selection screen select Select a server from the server pool and click Next.
On the Server Roles screen scroll down until you see Remote Access (RAS) (if this doesn’t appear on your screen then scroll further down until you see Network Policy and Access Services). Click on Network Policy and Access Services and then click Next.
On the Features page click Next twice to proceed with installation.
Radius server is the server that is used to authenticate the users. There are two types of radius servers:
Radius server authentication- It is used to provide authentication services to clients.
Radius server for wifi- It is used to provide wireless network access services.
The Microsoft Windows Server operating system includes a built-in RADIUS server, which can be used as a shared resource for wireless access points (APs) and other devices that require RADIUS authentication or accounting services. You can also install a RADIUS proxy to allow multiple devices on your network to use a single RADIUS server for authentication and accounting purposes.
How to Install Radius Server on Domain Controller
If you want to use Windows Active Directory for authentication, you’ll need to install the RADIUS server role. If you’re already running a RADIUS service, you can use it with your Active Directory domain.
NOTE: You can’t install any RADIUS services on a domain controller (DC). You can only install them on member servers or computers that aren’t DCs.
To install the RADIUS server role on a DC, first remove the DC role by following these steps:
In Server Manager, click Manage > Remove Roles and Features.
On the Before You Begin page, click Next.
On the Server Selection page, select your server from the Server Pool list and then click Next.
On the Remove Features page, select the Network Policy And Access Services check box and then click Next.
