I have created two network Internal-Users and Guest-Users, i verified the working of both the network in Windows 7,10,MAC OS,Android Device by importing Root CA and NPS certificate in the devices and configuring the Wireless Network manually by this case it works fine. Click on Configure 802.I have setup Windows 2012 R2 NPS Radius Server with self signed Certificate,it is working great with no issues. Open NPS Console, and Select RADIUS Server for 802.1x Wireless or Wired Connections.New-NpsRadiusClient -Name WLC2504 -Address 192.168.1.196 -sharedsecret -NapCompatible:$true #To add the NAP Server to "RAS and IAS Server" Group Enable NPS Role, Register it with AD Server and Create a RADIUS ClientĪdd-WindowsFeature -Name NPAS-Policy-Server -IncludeManagementTools.Generate & Import SSL Cert by following Request SSL Certificate from Microsoft CA with Certreq.The Wireless LAN Controller (WLC) and the LAP cannot decrypt these messages because it is not the TLS end point. The LAP and the controller only forward messages between the wireless client and RADIUS server. The NPS authenticates the wireless client with EAP-MS-CHAP v2. Phase 2 – EAP-Authenticated CommunicationĮAP communication, which includes EAP negotiation, occurs inside the TLS channel created by PEAP within the first stage of the PEAP authentication process. The key that is derived within this negotiation is used to encrypt all subsequent communication. After authentication is successfully completed between the wireless client and NPS, the TLS session is negotiated between the client and NPS. After the IEEE 802.11-based association is successfully established between the client and the access point, the TLS session is negotiated with the AP. PEAP does not specify an authentication method, but provides additional security for other Extensible Authentication Protocols (EAPs), such as EAP-MS-CHAP v2, that can operate through the TLS-encrypted channel provided by PEAP Phase 1 – TLS Encrypted ChannelĪn IEEE 802.11-based association provides an open system or shared key authentication before a secure association is created between the client and the access point. PEAP uses Transport Level Security (TLS) to create an encrypted channel between an authenticating PEAP client, such as a wireless laptop, and a PEAP authenticator, such as Microsoft NPS or any RADIUS server.
