Authenticating VPDN Users Using the RADIUS Server

Authenticating VPDN Users Using the RADIUS Server

An enterprise has a branch located in another city, and its branch network uses the Ethernet and has a gateway deployed, so branch hosts can access the Internet. A VPDN connection must be established between the headquarters gateway and the branch so that the headquarters can provide access services for users. Configure the branch gateway as the LAC and the headquarters gateway as the LNS to set up a VPDN connection. In addition, the branch gateway is configured as a PPPoE server to exchange PPP packets with the PPP client (branch user) over Ethernet. The LAC and LNS can authenticate branch users. However, when there are many users, a RADIUS server can be deployed to authenticate users remotely. The RADIUS server on the LAC side must support L2TP authentication. The RADIUS server determines whether remote users are VPDN users and sends the authentication result to the LAC.
