El Layer 2 Tunneling Protocol (L2TP) a través de IPSec se soporta en la versión 6.x o posterior de Cisco Secure PIX Firewall Software. Los usuarios con Windows 2000 pueden utilizar el cliente de IPSec nativo y el cliente de L2TP para establecer un túnel L2TP hasta el firewall PIX. El tráfico pasa por el túnel L2TP cifrado mediante Asociaciones de Seguridad IPSec (SA).
Nota: No puede utilizar el cliente IPSec L2TP de Windows 2000 para Telnet al PIX.
Nota: La tunelización dividida no está disponible con L2TP en el PIX.
Para configurar L2TP sobre IPSec desde clientes remotos de Microsoft Windows 2000/2003 y XP a una oficina corporativa de PIX/ASA Security Appliance usando claves previamente compartidas con un servidor RADIUS del Servicio de Autenticación de Internet (IAS) de Microsoft Windows 2003 para la autenticación de usuario, consulte L2TP sobre IPsec entre Windows 2000/XP PC y PIX/7 .2 Ejemplo de Configuración de Clave Previamente Compartida.
Para configurar L2TP sobre seguridad IP (IPsec) desde clientes Microsoft Windows 2000 y XP remotos a un sitio corporativo mediante un método cifrado, consulte Configuración de L2TP sobre IPSec desde un cliente Windows 2000 o XP a un concentrador Cisco VPN 3000 Series usando claves previamente compartidas.
No hay requisitos específicos para este documento.
La información de este documento se aplica a estas versiones de software y hardware:
Software PIX versión 6.3(3)
Windows 2000 con o sin SP2 (consulte la sugerencia de Microsoft Q276360 para obtener información sobre SP1.)
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.
El soporte de certificados en las versiones 6.x o posteriores de Cisco Secure PIX incluye servidores Baltimore, Microsoft, VeriSign y Entrust. Actualmente, PIX no acepta solicitudes L2TP sin protección IPSec.
Este ejemplo muestra cómo configurar el Firewall PIX para el escenario mencionado anteriormente en este documento. La autenticación de Internet Key Exchange (IKE) utiliza el comando rsa-sig (certificados). En este ejemplo, la autenticación es realizada por un servidor RADIUS.
Las opciones menos involucradas para las conexiones de cliente cifradas al PIX se enumeran en Cisco Hardware y VPN Clients Support IPSec/PPTP/L2TP.
En esta sección encontrará la información para configurar las funciones descritas en este documento.
Nota: Use la Command Lookup Tool (sólo clientes registrados) para obtener más información sobre los comandos utilizados en este documento.
En este documento, se utiliza esta configuración de red:
La información sobre cómo configurar el cliente Microsoft L2TP se encuentra en la Guía Paso a Paso de Microsoft para la Seguridad del Protocolo de Internet de Microsoft.
Como se indica en la guía paso a paso de Microsoft a la que se hace referencia, el cliente admite varios servidores de autoridad certificadora (CA) probados. La información sobre cómo configurar la CA de Microsoft se encuentra en la Guía paso a paso de Microsoft para configurar una autoridad de certificados.
Consulte Ejemplos de Configuración de CA para obtener detalles sobre cómo configurar PIX para la interoperabilidad con certificados de VeriSign, Entrust, Baltimore y Microsoft.
