PIX à PIX 6.x : Exemple de configuration Easy VPN (NEM)
Contenu
Introduction
Ce document fournit un exemple de configuration pour IPsec entre le client matériel Easy VPN Remote PIX et le serveur Easy VPN PIX. La fonctionnalité Easy VPN Remote pour le PIX a été introduite dans PIX version 6.2 et est également appelée client matériel/EzVPN. Cisco Easy VPN Server est pris en charge dans le logiciel PIX version 6.0 et ultérieure.
Référez-vous à Exemple de configuration de PIX/ASA 7.x Easy VPN avec un ASA 5500 en tant que serveur et PIX 506E en tant que client (NEM) afin d'en savoir plus sur le même scénario où l'appliance de sécurité fonctionne avec la version 7.x du logiciel.
Référez-vous à Exemple de configuration Easy VPN PIX/ASA 7.x avec un ASA 5500 comme serveur et Cisco 871 comme exemple de configuration Easy VPN Remote pour plus d'informations sur un scénario similaire où le routeur Cisco 871 agit comme Easy VPN Remote.
Référez-vous à Exemple de configuration du client matériel VPN sur un dispositif de sécurité de la gamme PIX 501/506 avec concentrateur VPN 3000 pour plus d'informations sur un scénario similaire où le concentrateur VPN Cisco 3000 agit comme serveur Easy VPN.
Référez-vous à Exemple de configuration de Easy VPN Remote vers un routeur IOS PIX 501/506 en mode d'extension de réseau avec authentification étendue pour plus d'informations sur un scénario similaire où le routeur Cisco IOS® agit en tant que serveur Easy VPN Server.
