PIX-zu-PIX 6.x: Konfigurationsbeispiel für Easy VPN (NEM)

Einführung

Dieses Dokument enthält eine Beispielkonfiguration für IPsec zwischen dem PIX Easy VPN Remote Hardware Client und dem PIX Easy VPN Server. Die Easy VPN Remote-Funktion für PIX wurde in PIX Version 6.2 eingeführt und wird auch als Hardware-Client/EzVPN-Client bezeichnet. Cisco Easy VPN Server wird von der PIX Software 6.0 und höher unterstützt.

Unter PIX/ASA 7.x Easy VPN mit ASA 5500 als Server und PIX 506E als Client (NEM) Konfigurationsbeispiel erfahren Sie mehr über dasselbe Szenario, in dem die Sicherheits-Appliance mit der Softwareversion 7.x ausgeführt wird.

Weitere Informationen zu einem ähnlichen Szenario, in dem der Cisco 871 Router als Easy VPN-Remote fungiert, finden Sie unter PIX/ASA 7.x Easy VPN mit ASA 5500 als Server und Cisco 871 als Easy VPN Remote-Konfigurationsbeispiel.

Weitere Informationen zu einem ähnlichen Szenario, in dem der Cisco VPN 3000 Concentrator als Easy VPN-Server fungiert, finden Sie im VPN Hardware Client auf einer Sicherheitslösung der Serie PIX 501/506 mit VPN 3000 Concentrator.

Unter PIX 501/506 Easy VPN Remote zu einem IOS-Router im Netzwerkerweiterungsmodus mit erweiterter Authentifizierungskonfiguration finden Sie weitere Informationen zu einem ähnlichen Szenario, in dem der Cisco IOS® Router als Easy VPN-Server fungiert.

Voraussetzungen

Anforderungen

Stellen Sie sicher, dass Sie diese Anforderungen erfüllen, bevor Sie versuchen, diese Konfiguration durchzuführen:

• Stellen Sie sicher, dass es sich beim PIX Easy VPN Remote Hardware Client um PIX 501 oder PIX 506/506E handelt, auf dem die PIX Software Version 6.2 oder höher ausgeführt wird.

• Stellen Sie sicher, dass es sich bei Ihrem Easy VPN-Server um eine PIX-Firewall handelt, die die PIX Software 6.0 oder höher ausführt.

Verwendete Komponenten

Die Informationen in diesem Dokument basieren auf den folgenden Software- und Hardwareversionen:

• PIX Easy VPN Remote Hardware Client ist ein PIX 501, der PIX Software Version 6.3(1) ausführt.

• Easy VPN Server ist ein PIX 515, der die PIX Software Version 6.3(1) ausführt.

Die Informationen in diesem Dokument wurden von den Geräten in einer bestimmten Laborumgebung erstellt. Alle in diesem Dokument verwendeten Geräte haben mit einer leeren (Standard-)Konfiguration begonnen. Wenn Ihr Netzwerk in Betrieb ist, stellen Sie sicher, dass Sie die potenziellen Auswirkungen eines Befehls verstehen.

Fehlerbehebung

Dieser Abschnitt enthält Informationen zur Fehlerbehebung in Ihrer Konfiguration.

Wenn Sie den Easy VPN Remote Hardware Client und den Easy VPN Server wie in diesem Dokument beschrieben eingerichtet haben und weiterhin Probleme auftreten, ermitteln Sie die Fehlerbehebungsausgabe jedes PIX und die Ausgabe der show-Befehle zur Analyse durch das Cisco Technical Assistance Center (TAC). Weitere Informationen finden Sie unter Fehlerbehebung für das PIX-System zur Weiterleitung des Datenverkehrs an einen etablierten IPsec-Tunnel oder IP-Sicherheitsfehlerbehebung - Verständnis und Verwenden von Debug-Befehlen. Aktivieren Sie IPsec-Debugging auf dem PIX.

Hier werden Befehle zum PIX-Debuggen und Beispielausgabe angezeigt.

• Easy VPN-Serverbefehle

• Befehle des Easy VPN Remote-Hardware-Clients

Hinweis: Beachten Sie vor der Verwendung von Debug-Befehlen die Informationen zu Debug-Befehlen.

Easy VPN-Serverbefehle

• debug crypto ipsec: Zeigt die IPsec-Verhandlungen von Phase 2 an.

• debug crypto isakmp: Zeigt die ISAKMP-Verhandlungen von Phase 1 an.
