IPSec Negotiation/IKE Protocols

Configure the PIX 501/506 Easy VPN Remote to an IOS Router in Network Extension Mode with Extended Authentication

Cisco - PIX 501/506 Easy VPN Remote to an IOS Router in Network Extension Mode with Extended Authentication Configuration Example

Introduction

This document illustrates the configuration of IPSec between the PIX Easy VPN Remote hardware client feature and Easy VPN Server feature available in later releases of Cisco IOS® Software. 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. When the Easy VPN Remote connects to a headend device, there are a minimum of five security associations (SAs), including one Internet Key Exchange (IKE) and four IPSec associations. When the Easy VPN Remote connects to the headend, it always negotiates two IPSec SAs with the IP address of the PIX's outside interface to any address behind the VPN server. This may be used for management purposes to connect to the PIX's outside interface from the network behind the Cisco IOS router (either via Secure Shell [SSH], Secure HTTP for PIX Device Manager [PDM], or Telnet). The SA is created by default without any configuration, and the other two SAs are created for the data traffic between the networks behind the PIX and the Cisco IOS router.

Refer to PIX-to-PIX 6.x: Easy VPN (NEM) Configuration Example for more information on a similar scenario where the PIX 506 6.x acts as the Easy VPN Server.

Refer to PIX/ASA 7.x Easy VPN with an ASA 5500 as the Server and PIX 506E as the Client (NEM) Configuration Example for more information on a similar scenario where the PIX/ASA 7.x acts as the Easy VPN Server.

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.

PIX show Commands and Sample Output

Use this section to confirm that your configuration works properly.

The Output Interpreter Tool (registered customers only) (OIT) supports certain show commands. Use the OIT to view an analysis of show command output.

  • vpnclient enable command—Enables an Easy VPN Remote connection. In NEM, the tunnel is up even when there is no interesting traffic to be exchanged with the headend Easy VPN Server.

    pix506(config)#vpnclient enable
    
  • show crypto isakmp policy—Displays the parameters for each IKE policy.

    pix506(config)#show crypto isakmp policy 
    
    Default protection suite 
            encryption algorithm:  DES - Data Encryption Standard (56 bit keys). 
            hash algorithm:        Secure Hash Standard 
            authentication method: Rivest-Shamir-Adleman Signature 
            Diffie-Hellman group:  #1 (768 bit) 
            lifetime:              86400 seconds, no volume limit

    This example shows output from the show crypto isakmp policy command after the hardware client is enabled.

    pix506(config)#show crypto isakmp policy 
    
    Protection suite of priority 65001
           encryption algorithm: DES - Data Encryption Standard (56 bit keys).
           hash algorithm: Message Digest 5
           authentication method: Pre-Shared Key with XAUTH
           Diffie-Hellman group: #2 (1024 bit)
           lifetime: 86400 seconds, no volume limit
    Protection suite of priority 65002
           encryption algorithm: DES - Data Encryption Standard (56 bit keys).
           hash algorithm: Message Digest 5
           authentication method: Pre-Shared Key
           Diffie-Hellman group: #2 (1024 bit)
           lifetime: 86400 seconds, no volume limit
  • show crypto ipsec transform—Displays the current IPSec transforms.

    pix506(config)#show crypto ipsec transform
    

    This example shows output from the show crypto ipsec transform command after the hardware client is enabled. Before the vpnclient enable command is used, there was only one default protection suite for ISAKMP. After the command is issued, Easy VPN Remote automatically builds four proposals in addition to the default protection suite. In addition, there is no IPSec transform set before the enable command is used. The transform set is built dynamically after the command is issued.

    pix506(config)#show crypto ipsec transform-set
    
    Transform set _vpnc_tset_9: { esp-des esp-md5-hmac } 
    will negotiate = { Tunnel, }, 
    
    Transform set _vpnc_tset_10: { esp-null esp-md5-hmac } 
    will negotiate = { Tunnel, }, 
    
    Transform set _vpnc_tset_11: { esp-null esp-sha-hmac } 
    will negotiate = { Tunnel, },
  • show crypto isakmp sa—Displays all current IKE SAs at a peer.

    pix506(config)#show crypto isakmp sa

Troubleshoot

Use this section to troubleshoot your configuration.

If you have set up the Easy VPN Remote (PIX) and Easy VPN Server (IOS) as described in this document and are still experiencing problems, please gather the debug output from the PIX and the IOS and output from the show command for analysis by the Cisco Technical Assistance Center (TAC). See also 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

PIX debug Commands

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

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

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