Introduction

This sample configuration shows how to set up multiple VPN Group Clients to use different VLANs after the IPsec tunnel is established with the PIX 500 Series Security Appliance.

Prerequisites

Requirements

Ensure that you meet this requirement before you attempt this configuration:

  • The PIX 500 Series Security Appliance 7.x and VPN Client 4.x are reachable from the Internet.

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

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.

Related Products

You can also use this configuration with the Cisco ASA 5500 Series Adaptive Security Appliance.

Conventions

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

Background Information

In this configuration example, there are two VPN Clients (user1 and user2) and there are two different VLANs named vlan2 and vlan3. Once the IPsec tunnel is established, user1 should be able to connect only to vlan2 and user2 should be able to connect only to vlan3.

Vlan2 is created under the sub-interface (Ethernet 1.1) and vlan3 is created under the sub-interface (Ethernet 1.2) of the Ethernet 1 interface of the PIX Security Appliance. You must enable the physical interface before any traffic can pass through an enabled sub-interface.

In general, if the IPsec tunnel is established from the Cisco VPN Client to the PIX Firewall, all the traffic is sent through the tunnel to the PIX Firewall. This can become very costly in terms of resource usage if many clients are connected at once. In order to avoid such heavy resource usage, you can use split tunneling. Split tunneling encrypts only the interesting traffic and the rest of the traffic goes to the Internet and does not get encrypted into the tunnel.

Note: If you would like to tunnel all traffic before you send it out to the Internet, refer to PIX/ASA 7.x and VPN Client for Public Internet VPN on a Stick Configuration Example for more information.

Configure

In this section, you are presented with the information to configure the multiple remote access VPN connections with the different VLANs in the PIX Security Appliance.

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

  3. 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 Tunnel Group name (in this case, vpn2) and the preshared key and click Save.

    multi-vpngroup-clients-diff-vlans-3.gif

  4. Click on the connection you would like to use and click Connect from the VPN Client main window.

    multi-vpngroup-clients-diff-vlans-4.gif

  5. When prompted, enter the Username and Password information configured in the PIX and click OK to connect to the remote network.

    multi-vpngroup-clients-diff-vlans-5.gif

  6. The Cisco VPN Client gets connected with the PIX at the central site.

    multi-vpngroup-clients-diff-vlans-6.gif

  7. Select Status > Statistics to check the tunnel statistics of the Cisco VPN Client.

    multi-vpngroup-clients-diff-vlans-7.gif

  8. Select Status > Statistics and click Route Details to check the route details of the Cisco VPN Client.

    The access list gets downloaded from the PIX to form the secured network connection for the network specified in the access list. The rest of the traffic directly enters into the Internet without encrypting into the tunnel.

Troubleshoot

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

Troubleshooting Commands

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 and IP Security Troubleshooting - Understanding and Using 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.

Clear SAs

When a change is made to the tunnel configuration, be sure to clear the SAs. Use these commands in the privileged mode of the PIX:

  • 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.
