PIX-to-PIX 6.x: Easy VPN (NEM) Configuration Example

Introduction

This document provides a sample configuration for IPsec between the PIX Easy VPN Remote Hardware Client and the PIX Easy VPN Server. The Easy VPN Remote feature for the PIX was introduced in PIX version 6.2 and is also referred to as hardware client/EzVPN client. Cisco Easy VPN Server is supported in PIX Software version 6.0 and later.

Refer to PIX/ASA 7.x Easy VPN with an ASA 5500 as the Server and PIX 506E as the Client (NEM) Configuration Example in order to learn more about the same scenario where the security appliance runs with software version 7.x.

Refer to PIX/ASA 7.x Easy VPN with an ASA 5500 as the Server and Cisco 871 as the Easy VPN Remote Configuration Example for more information on a similar scenario where the Cisco 871 Router acts as the Easy VPN Remote.

Refer to VPN Hardware Client on a PIX 501/506 Series Security Appliance with VPN 3000 Concentrator Configuration Example for more information on a similar scenario where the Cisco VPN 3000 Concentrator acts as the Easy VPN Server.

Refer to PIX 501/506 Easy VPN Remote to an IOS Router in Network Extension Mode with Extended Authentication Configuration Example for more information on a similar scenario where the Cisco IOS® Router acts as the Easy VPN Server.

Prerequisites

Requirements

Ensure that you meet these requirements before you attempt this configuration:

• Ensure that your PIX Easy VPN Remote Hardware Client is a PIX 501 or PIX 506/506E that runs PIX Software version 6.2 or later.

• Ensure that your Easy VPN Server is a PIX Firewall that runs PIX Software version 6.0 or later.

Components Used

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

• PIX Easy VPN Remote Hardware Client is a PIX 501 that runs PIX Software version 6.3(1).

• Easy VPN Server is a PIX 515 that runs PIX Software version 6.3(1).

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.

Conventions

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

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

If you have set up the Easy VPN Remote Hardware Client and Easy VPN Server as described in this document and still experience problems, gather the debug output from each PIX and the output from the show commands for analysis by the Cisco Technical Assistance Center (TAC). Also refer to Troubleshooting the PIX to Pass Data Traffic on an Established IPsec Tunnel or IP Security Troubleshooting - Understanding and Using debug Commands. Enable IPsec debugging on the PIX.

PIX debug commands and sample output are shown here.

• Easy VPN Server Commands

• Easy VPN Remote Hardware Client Commands

Note: Refer to Important Information on Debug Commands before you use debug commands.

Easy VPN Server Commands

• debug crypto ipsec—Displays the IPsec negotiations of Phase 2.

• debug crypto isakmp—Displays the ISAKMP negotiations of Phase 1.

This is sample output.

pix515(config)# 

!--- As soon as the vpnclient enable command !--- is issued on the remote client PIX, !--- the server receives an IKE negotiation request.
