Inklusive Sprache

In dem Dokumentationssatz für dieses Produkt wird die Verwendung inklusiver Sprache angestrebt. Für die Zwecke dieses Dokumentationssatzes wird Sprache als „inklusiv“ verstanden, wenn sie keine Diskriminierung aufgrund von Alter, körperlicher und/oder geistiger Behinderung, Geschlechtszugehörigkeit und -identität, ethnischer Identität, sexueller Orientierung, sozioökonomischem Status und Intersektionalität impliziert. Dennoch können in der Dokumentation stilistische Abweichungen von diesem Bemühen auftreten, wenn Text verwendet wird, der in Benutzeroberflächen der Produktsoftware fest codiert ist, auf RFP-Dokumentation basiert oder von einem genannten Drittanbieterprodukt verwendet wird. Hier erfahren Sie mehr darüber, wie Cisco inklusive Sprache verwendet.

    Einführung

    Dieses Dokument enthält eine Beispielkonfiguration zum Aktivieren der Adaptive Security Appliance (ASA), um dynamische IPsec-Verbindungen vom IOS-Router zu akzeptieren.

    Voraussetzungen

    Anforderungen

    Stellen Sie vor dem Versuch dieser Konfiguration sicher, dass sowohl die ASA als auch der Router über eine Internetverbindung für die Einrichtung des IPsec-Tunnels verfügen.

    In diesem Dokument wird davon ausgegangen, dass Sie die IP-Adressen bereits an den öffentlichen und privaten Schnittstellen zugewiesen haben und dass Sie die IP-Adresse des Remote-VPN-Geräts pingen können.

    Verwendete Komponenten

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

    • Cisco 2900 Router mit Cisco IOS Software, Version 15.2(4)M3

    • Cisco Adaptive Security Appliance Software Version 9.4(1)

    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.

    Konventionen

    Weitere Informationen zu Dokumentkonventionen finden Sie in den Cisco Technical Tips Conventions (Technische Tipps zu Konventionen von Cisco).

    Hintergrundinformationen

    Der Remote-Router führt Network Address Translation (NAT) aus, wenn das private Netzwerk 10.1.1.x auf das Internet zugreift. Der hinter der ASA liegende Datenverkehr von 10.1.1.x zum privaten Netzwerk 10.2.2.x ist vom NAT-Prozess ausgeschlossen. Der IPsec-Tunnel wird nur eingerichtet, wenn der Datenverkehr (10.1.1.x) die Verbindung vom Router mit der ASA initiiert, die über ein Remote-Netzwerk (10.2.2.x) verfügt. Der Router kann Verbindungen zur ASA initiieren, aber die ASA kann keine Verbindungen zum Router initiieren.

    Mit dieser Konfiguration kann die ASA einen dynamischen IPsec-LAN-to-LAN (L2L)-Tunnel mit einem Remote-VPN-Router erstellen. Dieser Router erhält seine externe öffentliche IP-Adresse dynamisch von seinem Internetdienstanbieter. Dynamic Host Configuration Protocol (DHCP) stellt diesen Mechanismus bereit, um IP-Adressen dynamisch vom Anbieter zuzuweisen. Dadurch können IP-Adressen wiederverwendet werden, wenn Hosts sie nicht mehr benötigen.

     Auf der ASA können Sie eine manuelle NAT konfigurieren, um sicherzustellen, dass der Datenverkehr, der den Tunnel durchläuft, nicht übersetzt wird. In diesem Beispiel wird, wenn Sie sich im Netzwerk 10.2.2.0 befinden und zum Netzwerk 10.1.1.0 wechseln, das Manual NAT verwendet, um die Verschlüsselung des 10.1.1.0-Netzwerkverkehrs zu ermöglichen, ohne in die IP-Adresse der externen Schnittstelle übersetzt zu werden. Auf dem Router werden die Befehle route-map und access-list verwendet, um die Verschlüsselung des 10.1.1.0-Netzwerkverkehrs ohne NAT zu ermöglichen. Wenn Sie jedoch an einen anderen Ort (z. B. das Internet) gehen, werden Sie mithilfe von Port Address Translation (PAT) in die IP-Adresse der externen Schnittstelle übersetzt.

    Hinweis: Weitere Informationen zu NAT finden Sie unter Anwenden von NAT.

    Dies sind die Konfigurationsbefehle, die auf der ASA erforderlich sind, damit der Datenverkehr nicht über PAT im Tunnel läuft und der Datenverkehr zum Internet über PAT läuft.
