Cisco IOS Easy VPN リモートハードウェアクライアント

はじめに

このドキュメントでは、Cisco IOS® Easy VPNリモートハードウェアクライアントとPIX Easy VPNサーバ間のIPSecの設定例を紹介します。

注：Easy VPNリモート機能は、ハードウェアクライアントおよびEzVPNクライアントとも呼ばれます。

Cisco VPN 3000コンセントレータに接続するためにCisco IOSルータをNetwork Extension Mode(NEM)でEzVPNとして設定する方法については、『VPN 3000コンセントレータを使用したIOSルータでのNEMを使用したEzVPNの設定例』を参照してください。

Easy VPNを使用してCisco PIX/ASA 7.xとCisco 871ルータ間にIPSecを設定する方法については、『PIX/ASA 7.x以降：スプリットトンネリングASA 5500をサーバ、Cisco 871をEasy VPN Remoteとして使用するEasy VPNの設定例』を参照してください。

Cisco 7200ルータをEzVPNとして、Cisco 871ルータをEasy VPN Remoteクライアントとして設定する方法については、『IOSルータ：ネットワーク拡張モード(NEM)でのEasy VPN(EzVPN)の設定例』を参照してください。

前提条件

要件

この設定を行う前に、次の要件が満たされていることを確認します。

使用している Cisco IOS およびハードウェアが、Easy VPN リモート機能をサポートしている。Software Advisor(登録ユーザ専用)を参照してください。
使用している Easy VPN サーバは、PIX ソフトウェアバージョン 6.2 以降が稼働している PIX ファイアウォールである。
使用している PIX に 3DES ライセンスがインストールされている。「アクティベーションキーのアップグレード」を参照してください。

使用するコンポーネント

このドキュメントの情報は、次のソフトウェアとハードウェアのバージョンに基づいています。

Cisco IOS Easy VPNリモートハードウェアクライアントは、Cisco IOSソフトウェアリリース12.3(8)Tが稼働する831ルータです。
Easy VPNサーバは、PIXソフトウェアバージョン6.3(3)が稼働するPIX 525です。

このドキュメントの情報は、特定のラボ環境にあるデバイスに基づいて作成されました。このドキュメントで使用するすべてのデバイスは、クリアな（デフォルト）設定で作業を開始しています。対象のネットワークが実稼働中である場合には、どのようなコマンドについても、その潜在的な影響について確実に理解しておく必要があります。

表記法

表記法の詳細については、『シスコテクニカルティップスの表記法』を参照してください。
