PIX/ASA 7.x and Cisco VPN Client 4.x for Cisco Secure ACS Authentication Configuration Example

Introduction

This sample configuration shows how to set up a remote access VPN connection between a Cisco VPN Client (4.x for Windows) and the PIX 500 Series Security Appliance 7.x using a Cisco Secure Access Control Server (ACS version 3.2) for extended authentication (Xauth).

Refer to PIX/ASA 7.x and Cisco VPN Client 4.x for Windows with Microsoft Windows 2003 IAS RADIUS Authentication Configuration Example in order to learn more about the same scenario in PIX/ASA 7.x with Cisco VPN Client 4.8.

Refer to Cisco Secure PIX Firewall 6.x and Cisco VPN Client 3.5 for Windows with Microsoft Windows 2000 and 2003 IAS RADIUS Authentication in order to learn more about the same scenario in PIX 6.x with Cisco VPN Client 3.5.

Prerequisites

Requirements

Ensure that the PIX 500 Series Security Appliance is reachable from the Internet before you attempt this configuration.

Components Used

The information in this document is based on these software and hardware versions:

PIX 515E Series Security Appliance Software Release 7.1(1)
Cisco VPN Client version 4.8 for Windows
Cisco Secure Access Control Server (ACS) version 3.2

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

Background Information

Remote access VPNs address the requirement of the mobile workforce to securely connect to the organization's network. Mobile users are able to set up a secure connection using the VPN Client software installed on their PCs. The VPN Client initiates a connection to a central site device configured to accept these requests. In this example, the central site device is a PIX 500 Series Security Appliance that uses dynamic crypto maps.

In this configuration example, an IPsec tunnel is configured with these elements:

Crypto maps applied to the outside interfaces on the PIX.
Xauth of the VPN Clients against a RADIUS database.
Dynamic assignment of a private IP address from a pool to VPN Clients.
The nat 0 access-list command functionality, which allows hosts on a LAN to use private IP addresses with a remote user and still get a Network Address Translation (NAT) address from the PIX to visit an untrusted network.

Configure

In this section, you are presented with the information to configure the remote access VPN connection with Xauth using the Windows 2003 Internet Authentication Service (IAS) server.

Note: Use the Command Lookup Tool (registered customers only) to obtain more information on the commands used in this section.

VPN Client 4.8 Configuration

Complete these steps to configure VPN Client 4.8.

Choose Start > Programs > Cisco Systems VPN Client > VPN Client.
Click New to launch the Create New VPN Connection Entry window.
Enter the name of the Connection Entry along with a description. Enter the outside IP address of the PIX Firewall in the Host box. Then enter the VPN Group name and password and click Save.
Click on the connection you would like to use and click Connect from the VPN Client main window.
When prompted, enter the Username and Password information for Xauth and click OK to connect to the remote network.
The VPN Client gets connected with the PIX at the central site.
Choose Status > Statistics to check the tunnel statistics of the VPN Client.

Configure the RADIUS Server Using Cisco Secure ACS

Complete these steps in order to configure RADIUS in a Cisco Secure ACS.

Choose Network Configuration on the left and click Add Entry to add an entry for the PIX in either the TACACS+ or RADIUS server database. Choose the server database according to the PIX configuration.
Enter 10.11.1.1 in the Client IP Address field, and enter cisco123 for the shared secret Key field. Choose RADIUS (Cisco IOS/PIX) in the Authenticate Using drop-down box. Click Submit. .

Note: The shared secret key should be the same as configured in the PIX.
```
aaa-server vpn host 10.11.1.2
 key cisco123
```
Note: If you want to select the TACACS+ protocol for authentication, then choose TACACS+(Cisco IOS) in the Authenticate Using drop-down menu.
Enter the username in the User field in the Cisco Secure database, then click Add/Edit.

In this example, the username is administrator.
In the next window, enter the password for administrator. In this example, the password is also password1. You can map the user account to a group if you wish. Click Submit when you are done.

Verify

AAA Authentication

From the PIX, use the Test keyword with the aaa authentication command in global configuration mode to verify the user authentication with the AAA server. After you enter the command, the PIX prompts you to enter the username and password to validate. When the user credential is verified and it is valid, you receive the Authentication Successful message.

pix(config-aaa-server-host)#test aaa authentication radius host 10.11.1.2

Username: administrator
Password: *****

INFO: Attempting Authentication test to IP address <10.11.1.2> (timeout: 12 sec

Troubleshoot

This section provides information you can use to troubleshoot your configuration. Sample debug output is also shown.

Clear Security Associations

When you troubleshoot, be sure to clear existing Security Associations after you make a change. In the privileged mode of the PIX, use these commands:

clear [crypto] ipsec sa—Deletes the active IPsec SAs. The keyword crypto is optional.
clear [crypto] isakmp sa—Deletes the active IKE SAs. The keyword crypto is optional.
