Introducción

Este documento describe cómo configurar la seguridad IP (IPSec) sobre el protocolo de control de transmisión (TCP). Esto permite que un cliente VPN funcione en un entorno en el que el protocolo estándar de seguridad de encapsulación (ESP, protocolo 50) o el intercambio de claves de Internet (IKE, protocolo de datagramas de usuario (UDP) 500) no pueden funcionar o sólo pueden funcionar con la modificación de las reglas de firewall existentes. IPSec sobre TCP encapsula tanto los protocolos IKE como IPSec dentro de un paquete TCP, y permite tunelización segura a través de dispositivos y firewalls de traducción de direcciones de red (NAT) y de traducción de direcciones de puerto (PAT).

Nota: IPSec sobre TCP no funciona con firewalls basados en proxy.

IPSec sobre TCP funciona tanto con el VPN Software Client como con el VPN 3002 Hardware Client. Es una función de cliente a concentrador solamente. No funciona para las conexiones de LAN a LAN.

El concentrador VPN 3000 puede soportar simultáneamente IPSec estándar, IPSec sobre TCP e IPSec sobre UDP, en función del cliente con el que intercambia datos.

El cliente de hardware VPN 3002, que admite un túnel a la vez, puede conectarse mediante IPSec estándar, IPSec sobre TCP o IPSec sobre UDP.

Prerequisites

Requirements

Se debe configurar la interfaz pública del concentrador VPN 3000. IPSec sobre TCP sólo se admite en la interfaz pública en Ethernet 2. Consulte Notas de la Versión de Cisco VPN Client para obtener más información.

Componentes Utilizados

La información que contiene este documento se basa en las siguientes versiones de software y hardware.

  • VPN 3000 Concentrator versión 3.5 o posterior

  • VPN Client versión 3.5 o posterior

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.

Configurar el concentrador VPN 3000

Step-by-Step Instructions

Complete estos pasos para configurar el VPN 3000 Concentrator.

  1. Vaya a Configuration > User Management > Groups > Add Group y cree un nombre de grupo y una contraseña en el VPN Concentrator. Haga clic en Agregar una vez finalizado.

    vpn3k_ipsec_tcp_01.gif

  2. Si el mismo grupo está siendo utilizado por los usuarios en las versiones de VPN Client anteriores a 3.5, o si está utilizando IPSec sobre UDP en VPN Client, seleccione IPSec sobre UDP en la pestaña Client Config.

    vpn3k_ipsec_tcp_02a.gif

  3. Vaya a Configuration > User Management > Users > Modify esupport. Si utiliza la autenticación interna, cree un usuario para autenticarse en el grupo. A continuación, asigne el usuario a ese grupo.

    vpn3k_ipsec_tcp_03.gif

  4. Vaya a Configuration > Tunneling and Security > NAT Transparency y seleccione la opción IPsec over TCP

    Introduzca hasta 10 puertos, utilizando una coma para separar los puertos. No es necesario utilizar espacios. El puerto predeterminado es 10,000. El rango va de 1 a 65,635.

    Si ingresa un puerto conocido (como el puerto 80 (HTTP) o el puerto 443 (HTTPS), el sistema muestra una advertencia de que el protocolo asociado a ese puerto ya no funciona en la interfaz pública. La consecuencia es que ya no puede utilizar un navegador para administrar el concentrador VPN 3000 a través de la interfaz pública. Para solucionar este problema, vuelva a configurar la administración HTTP/HTTPS en diferentes puertos.

    Debe configurar los puertos TCP en el VPN Client así como en el VPN Concentrator. La configuración del cliente debe incluir al menos uno de los puertos configurados para el concentrador VPN aquí.

Configure el cliente VPN

Complete estos pasos para configurar el VPN Client.

  1. Vaya a Opciones > Propiedades. En la ficha General, marque Enable Transparent Tunneling y elija Use IPSec over TCP (NAT/PAT/Firewall).

    vpn3k_ipsec_tcp_05a.gif

  2. En la ficha Autenticación, configure un nombre de grupo y una contraseña en el cliente.

    vpn3k_ipsec_tcp_06.gif

Verifique las conexiones en el concentrador VPN 3000

El área Monitoring > Sessions en el VPN 3000 Concentrator verifica la conexión de usuarios con el mismo grupo para IPSec sobre TCP e IPSec sobre UDP.

Troubleshoot

En esta sección encontrará información que puede utilizar para solucionar problemas de configuración.

Comandos para resolución de problemas

La herramienta Output Interpreter (sólo para clientes registrados) permite utilizar algunos comandos “show” y ver un análisis del resultado de estos comandos.

Nota: Antes de ejecutar comandos debug, consulte Información Importante sobre Comandos Debug.

Habilite las depuraciones para AUTH, AUTHDBG, AUTHDECODE, IKE, IKEDBG, IKEDECODE, IPSEC, IPSECDBG, IPSECDECODE para los niveles 1 a 13 bajo Configuration > System > Events > Classes.
