Ejemplo de Configuración de Easy VPN PIX/ASA 7.x con ASA 5500 como Servidor y PIX 506E como Cliente (NEM)
Contenido
Introducción
Este documento proporciona una configuración de ejemplo para IPSec entre un Cisco Adaptive Security Appliance (ASA) 5520 y un router Cisco PIX 506E que usa EasyVPN. El ASA 5520 actúa como servidor EasyVPN y el PIX 506E actúa como cliente remoto del EasyVPN. Mientras que esta configuración utiliza un dispositivo ASA 5520 que ejecuta la versión de software ASA 7.0(4), también puede utilizar esta configuración para los dispositivos de firewall PIX que ejecutan la versión del sistema operativo 7.0 del PIX y posterior.
Consulte PIX/ASA 7.x Easy VPN con ASA 5500 como servidor y Cisco 871 como ejemplo de configuración de Easy VPN remoto para obtener más información sobre un escenario similar en el que el router Cisco 871 actúa como Easy VPN remoto.
Refiérase a Ejemplo de Configuración de VPN Hardware Client en un PIX 501/506 Series Security Appliance con VPN 3000 Concentrator para obtener más información sobre un escenario similar donde el Cisco VPN 3000 Concentrator actúa como el Easy VPN Server.
Consulte Ejemplo de Configuración de Easy VPN Remote PIX 501/506 a un Router IOS® en Modo de Extensión de Red con Autenticación Extendida para obtener más información sobre un escenario similar donde el Router Cisco IOS actúa como Servidor Easy VPN.
Consulte PIX-to-PIX 6.x: Ejemplo de Configuración de Easy VPN (NEM) para obtener más información sobre un escenario similar en el que el PIX 506 6.x actúa como servidor Easy VPN.
Prerequisites
Requirements
Asegúrese de cumplir estos requisitos antes de intentar esta configuración:
-
Asegúrese de tener una comprensión básica de los sistemas operativos IPSec y ASA/PIX 6.x y 7.x.
Componentes Utilizados
La información que contiene este documento se basa en las siguientes versiones de software y hardware.
-
El cliente de hardware remoto EasyVPN es un PIX 506E que ejecuta la versión 6.3(5).
-
El servidor Easy VPN es un ASA 5520 que ejecuta la versión 7.0(4).
Nota: La versión 7.x de ASA serie 5500 ejecuta el mismo software visto en la versión 7.x de PIX. Las configuraciones en este documento son aplicables a ambas líneas de producto.
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.
