This document illustrates an IPsec configuration that includes both gateway-to-gateway and remote user functionality. With extended authentication (Xauth), the device is authenticated through the pre-shared key and the user is authenticated through a user-name/password challenge.
There are no specific requirements for this document.
The information in this document is based on these software and hardware versions:
PIX Firewall Version 6.3(3)
Cisco VPN Client Version 3.5
Cisco Secure ACS for Windows Version 2.6
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 Cisco Technical Tips Conventions for more information on document conventions.
In this example, there is a gateway-to-gateway IPsec tunnel from the remote PIX to the hub PIX. This tunnel encrypts the traffic from network 10.48.67.x behind the remote PIX to network 10.48.66.x behind the hub PIX. The PC on the Internet can form an IPsec tunnel through the hub PIX to network 10.48.66.x.
In order to use the Xauth feature, you must first set up your basic authentication, authorization, and accounting (AAA) server. Use the crypto map client authentication command to tell the PIX Firewall to use the Xauth (RADIUS/TACACS+ user name and password) challenge during Phase 1 of Internet Key Exchange (IKE) in order to authenticate IKE. If the Xauth fails, the IKE security association is not established. Specify the same AAA server name within the crypto map client authentication command statement that is specified in the aaa-server command statement. The remote user must run Cisco VPN Client version 3.x. or later.
Note: Cisco recommends you use Cisco VPN Client 3.5.x or later. VPN Client 1.1 does not work with this configuration and is out of the scope of this document.
Note: Cisco VPN Client 3.6 and later does not support the transform set of des/sha.
If you need to restore the configuration without Xauth, use the no crypto map client authentication command. The Xauth feature is not enabled by default.
Note: Encryption technology is subject to export controls. It is your responsibility to know the law related to the export of encryption technology. Refer to the Bureau of Export Administration home page for more information. Send an E-mail to export@cisco.com if you have any questions related to export control.
Note: In PIX Firewall Version 5.3 and later, configurable RADIUS ports were introduced. Some RADIUS servers use RADIUS ports other than 1645/1646 (usually 1812/1813). In PIX 5.3 and later, the RADIUS authentication and accounting ports can be changed to ones other than the default 1645/1646 using these commands:
aaa-server radius-authport # aaa-server radius-acctport #
In this section, you are presented with the information to configure the features described in this document.
Note: Use the Command Lookup Tool (registered customers only) to find more information on the commands used in this document.
This diagram uses green and black bold lines in order to indicate the VPN tunnels.
This document uses these configurations.
Note: For the example in this document, the IP address of the VPN server is 209.165.200.225, the group name is "vpn3000," and the group password is cisco.

Refer to the "Configurations" section of Configuring PIX to PIX and VPN Client 3.x for detailed information about how to set up the VPN Client. Also, refer to How to Add AAA Authentication (Xauth) to PIX IPsec 5.2 and Later for additional information on the configuration of AAA Authentication to PIX IPsec.
This section provides information you can use in order to confirm 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.
show crypto isakmp sa—Shows Phase 1 security associations.
show crypto ipsec sa—Shows Phase 2 security associations.
This section provides information you can use to troubleshoot your configuration.
The Output Interpreter Tool (registered customers only) (OIT) supports certain show commands. Use the OIT to view an analysis of show command output.
Note: Refer to Important Information on Debug Commands before you use debug commands.
These debugs must run on both IPsec routers (peers). Security associations must be cleared on both peers.
debug crypto isakmp—Displays errors during Phase 1.
debug crypto ipsec—Displays errors during Phase 2.
debug crypto engine—Displays information from the crypto engine.
clear crypto isakmp sa—Clears the Phase 1 security associations.
clear crypto ipsec sa—Clears the Phase 2 security associations.
debug radius [session | all | user username]—Available in PIX 6.2, this command logs RADIUS session information and the attributes of sent and received RADIUS packets.
debug tacacs [session|user <user_name>]—Available in PIX 6.3, this command logs TACACS information.
debug aaa [authentication|authorization|accounting|internal]—Available in PIX 6.3, shows AAA subsystem information.
Note: Be aware that sometimes when IPsec negotiation is successful, not all of the debugs get shown on the PIX due to Cisco bug ID CSCdu84168 (registered customers only) which is a duplicate of internal Cisco bug ID CSCdt31745 (registered customers only) . This is not yet resolved as of the writing of this document.
Note: Sometimes the IPSec VPN from VPN Clients may not terminate on the PIX. In order to resolve this issue, ensure that client PC does not have any firewalls. If firewalls are present, check if UDP port 500 and 4500 are disabled. If this is the case, enable IPSec over TCP or unblock the UDP ports.
