Configuring PEAP
Benefits and
Purpose
PEAP (Protected Extensible Authentication Protocol) validates the
identity of devices or users before they gain access to network
resources. You can configure the TPG for the PEAP network
authentication. This makes sure that the TPG gets access to
protected networks.
Mode of Operation
In the case of PEAP (compare EAP-TTLS, see Ö65), an encrypted
TLS (Transport Layer Security) channel is established between the
TPG and the RADIUS server. Only the RADIUS server authenticates
itself using a certificate that was signed by a CA.
The TLS channel is then used to establish another connection that
can be protected by means of additional EAP authentication
methods (e.g. MSCHAPv2).
The advantage of this procedure is that only the RADIUS server
needs a certificate. Therefore no PKI is needed. PEAP uses the
advantages of TLS and supports various authentication methods,
including user passwords and one-time passwords.
Requirements
; The TPG is defined as user (with user name and password) on a
RADIUS server.
Proceed as follows:
1. Start the TPG Control Center.
2. Select SECURITY – Authentication.
3. Select PEAP from the Authentication method list.
4. Enter the user name and the password that are used for the
configuration of the TPG on the RADIUS server.
5. Select the settings intended to secure the communication in the
TLS channel.
6. To make the connection more secure, you can also install the
root certificate of the RADIUS server on the TPG (Ö60).
7. Click Save & Restart to confirm.
ª The settings are saved.
