Ejemplo de Configuración de LAN a LAN y EzVPN Client en PIX con Acceso de Cliente VPN a un Router Hub Usando Perfiles ISAKMP

Introducción

Este documento proporciona un ejemplo para la configuración de túneles IPSec utilizando perfiles ISAKMP en un router concentrador con dos sitios remotos PIX. Un sitio remoto PIX consta de una conexión LAN a LAN y el otro consta de una configuración de modo de acceso remoto EzVPN. El router hub está configurado para realizar una autenticación local para los túneles EzVPN, y una autenticación RADIUS para el software VPN Client.

Configuración de cliente VPN

Complete estos pasos para configurar el VPN Client.

1. Inicie VPN Client y cree una nueva conexión con los parámetros de entrada de conexión requeridos.

   

2. Una vez creada la entrada de conexión, haga clic en Connect (Conectar) y realice la autenticación con los parámetros de usuario configurados en el servidor RADIUS.

   

Verificación

En esta sección encontrará información que puede utilizar para confirmar que su configuración esté funcionando correctamente. Refiérase a Solución de Problemas de Seguridad IP - Comprensión y Uso de los Comandos de debug para verificación/Troubleshooting adicional. Si debe encontrar algún problema o error de VPN Client, consulte la Herramienta de Búsqueda de Errores de GUI de VPN Client.

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

• show crypto isakmp profile —Muestra todos los perfiles ISAKMP y sus configuraciones en el router.

• show crypto isakmp key—Muestra todos los anillos de claves y sus claves previamente compartidas. Utilice este comando para verificar la configuración del anillo fundamental con criptografía en el router.

• debug crypto ipsec: muestra información sobre las negociaciones SA IPSec en el router.

• debug crypto isakmp: muestra la SA ISAKMP que se genera y los atributos IPsec que se negocian. Durante la negociación ISAKMP SA, el PIX podría descartar varias propuestas como "no aceptables" antes de que se acepte una. Una vez que se haya acordado el ISAKMP SA, se negocian los atributos IPSec.
