Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

This document describes how to configure IP Security (IPSec) over Transmission Control Protocol (TCP). This enables a VPN Client to operate in an environment in which standard Encapsulating Security Protocol (ESP, Protocol 50) or Internet Key Exchange (IKE, User Datagram Protocol (UDP) 500) cannot function, or can function only with modification to existing firewall rules. IPSec over TCP encapsulates both the IKE and IPSec protocols within a TCP packet, and it enables secure tunneling through both Network Address Translation (NAT) and Port Address Translation (PAT) devices and firewalls.

Note: IPSec over TCP does not work with proxy-based firewalls.

IPSec over TCP works with both the VPN Software Client and the VPN 3002 Hardware Client. It is a client to concentrator feature only. It does not work for LAN-to-LAN connections.

The VPN 3000 Concentrator can simultaneously support standard IPSec, IPSec over TCP, and IPSec over UDP, based on the client with which it exchanges data.

The VPN 3002 Hardware Client, which supports one tunnel at a time, can connect using standard IPSec, IPSec over TCP, or IPSec over UDP.

Prerequisites

Requirements

The public interface of the VPN 3000 concentrator should be configured. IPSec over TCP is supported only on the public interface on Ethernet 2. Refer to the Cisco VPN Client Release Notes for more information.

Components Used

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

  • VPN 3000 Concentrator version 3.5 or later

  • VPN Client version 3.5 or later

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.

Configure the VPN 3000 Concentrator

Step-by-Step Instructions

Complete these steps to configure the VPN 3000 Concentrator.

  1. Go to Configuration > User Management > Groups > Add Group and create a group name and a password on the VPN Concentrator. Click Add upon completion.

  2. If the same group is being used by users on VPN Client versions earlier than 3.5, or if you are using IPSec over UDP on VPN Client, then select IPSec over UDP under the Client Config tab.

    vpn3k_ipsec_tcp_02a.gif

  3. Go to Configuration > User Management > Users > Modify esupport. If you are using internal authentication, create a user to authenticate to the group. Then assign the user to that group.

    vpn3k_ipsec_tcp_03.gif

  4. Go to Configuration > Tunneling and Security > NAT Transparency and select the IPsec over TCP option

    Enter up to 10 ports, using a comma to separate the ports. You do not need to use spaces. The default port is 10,000. The range is 1 to 65,635.

    If you enter a well-known port (such as port 80 (HTTP) or port 443 (HTTPS), the system displays a warning that the protocol associated with that port no longer works on the public interface. The consequence is that you can no longer use a browser to manage the VPN 3000 Concentrator through the public interface. To solve this problem, reconfigure the HTTP/HTTPS management to different ports.

    You must configure TCP port(s) on the VPN Client as well as on the VPN Concentrator. The client configuration must include at least one of the ports you set for the VPN Concentrator here.

Configure the VPN Client

Complete these steps to configure the VPN Client.

  1. Go to Options > Properties. Under the General tab, check Enable Transparent Tunneling and choose Use IPSec over TCP (NAT/PAT/Firewall).

  2. Under the Authentication tab, configure a group name and a password on the client.

Verify the Connections on the VPN 3000 Concentrator

The Monitoring > Sessions area on the VPN 3000 Concentrator verifies the connection of users with the same group for IPSec over TCP and IPSec over UDP.
