Use the following procedures to use the WebUI to configure a remote access VPN for L2TP IPsec.ДЄuthentication Method and Server AddressesДЎ. User-level authentication through a PPP-based authentication protocol using passwords, SecureID, digital certificates, or smart cards after successful creation of the SAs. L2TP/IPsec requires two levels of authentication:Д¬omputer-level authentication with a preshared key to create the IPsec security associations (SAs) to protect the L2TP-encapsulated data. With L2TP/IPsec, the user authentication process is encrypted using the Data Encryption Standard (DES) or Triple DES (3DES) algorithm. L2TP/IPsec relies on the PPP connection process to perform user authentication and protocol configuration. L2TP/IPsec provides both a logical transport mechanism on which to transmit PPP frames as well as tunneling or encapsulation so that the PPP frames can be sent across an IP network. The combination of Layer-2 Tunneling Protocol and Internet Protocol Security (L2TP/IPsec) is a highly-secure technology that enables VPN connections across public networks such as the Internet. Table 63 Supported VPN AAA Deployments (Continued) If a RAP-psk is using an external AAA server, then the RAP-cert cannot be terminated on the same controller.Д¬lients can use any type of AAA server irrespective of RAP/CAP authentication configuration server. Configuration rules include:ДЄ RAP-psk and RAP-cert can only terminate on the same controller if the RAP VPN profileвЂ™s AAA server uses Local-db. If you want to simultaneously deploy various combinations of a VPN client, RAP-psk, RAP-certs and CAP on the same controller, see Table 63.Д®ach row in this table specifies the allowed combinations of AAA servers for simultaneous deployment. To configure VPN authentication via the command-line interface, access the CLI in config mode andissue the following commands: From the drop-down menu, select the server group to be used for VPN authentication. In the default profile list, select Server Group.Д§. This number indicates the number of contiguous authentication failures before the station is blacklisted.Д¦. (Optional) Set Max Authentication failures to an integer value (the default value is 0, which disables this feature). Select the Default Role from the drop-down menu. In the Profiles list, select the default VPN Authentication Profile.ДЈ. Navigate to the Configuration >Security >Authentication > е…ѓ Authentication page.Дў. To configure VPN authentication via the WebUI:ДЎ. You then specify the default user role and authentication server group in the VPN authentication defaultprofile, as described in the following sections.

See Chapter 8, вЂњAuthentication ServersвЂќ for configuration details.ДЄ server-derived role, if present, takes precedence over the default user role. The authentication server group the controllerwill use to validate the clients. See Chapter 10, вЂњRoles and PoliciesвЂќ for information about configuring user roles. The default user role for authenticated VPN clients. All traffic for the other network is sent and received through a VPN gateway which encapsulates and encrypts the traffic.Д«efore enabling VPN authentication, you must configure the following: Unlike a remote access VPN, hosts in a site-to-site VPN do not run VPN client software. Site-to-site VPNs allow networks (for example, a branch office network) to connect to other networks (for example, a corporate network). Layer-2 Tunneling Protocol over IPsec (L2TP/IPsec) The controllersupports the following remote access VPN protocols:

Each host must run VPN client software which encapsulates and encrypts traffic and sends it to a VPN gateway at the destination network. Remote access VPNs allow hosts (for example, telecommuters or traveling employees) to connect to private networks (for example, a corporate network) over the Internet. You can configure the controller for the following types of VPNs: вЂњConfiguring a Remote Access VPN for PPTPвЂќ вЂњConfiguring Remote Access VPNs for XAuthвЂќ

This chapter describes the following topics: The Arubacontrollercan be used as a VPN concentrator that terminates all VPN connections from both wired and wireless clients.

For wireless networks, virtual private network (VPN) connections can be used to further secure the wireless data from attackers.
