The Select Dial-Up Or Virtual Private Network Connections Type page
Even if the wizard makes no other distinction during the process of creating the policies for
VPN and dial-up clients, the resulting policies are different. The policy for a VPN connection
is to use a NAS port type of Virtual (VPN). For dial-up, it is Async (Modem) OR ISDN Sync OR
ISDN AsyncV.120 OR ISDN Async V.110.
You can also configure a different set of users, authentication methods, realm, and encryp-
tion strength for dial-up and VPN clients, even when using the same server to support both
methods of remote access.
Configuring a raDIUS proxy
You can configure a RADIUS server to act as a proxy that forwards requests for RADIUS
authentication to other RADIUS servers, depending on the client making the request and the
connection request policies configured on the RADIUS server. A RADIUS proxy can also act as
a proxy for RADIUS Accounting, described later in this objective.
A RADIUS proxy acts as a traffic coordinator between RADIUS clients and other RADIUS
servers or other RADIUS proxies. An NPS server acting as a RADIUS proxy can connect to
other Microsoft NPS servers or third-party RADIUS servers, or any combination thereof.
Figure 4-9 shows a Microsoft NPS server acting as a RADIUS proxy.
