Windows 2000 VPN（PPTP）の設定

次のステップを実行します。

[Start] > [Settings] > [Network and Dial-up Connections] > [Make New ConnectionMake New Connection] を選択します。
Network Connection Wizard ウィンドウが表示されたら、Network Connection Type と Connect to a private network through the Internet を選択します。
Automatically dial this initial connection を選択します。
Host or IP address フィールドで Destination Address を指定して、Next をクリックします。
[Start] > [Settings] > [Network and Dial up connections] を選択して、直前に設定した接続を選択します。
このウィンドウが表示されたら、適切なオプションを設定するために [Properties] > [Security] を選択します。
Advanced (customer settings) を選択し、次に Settings を選択してから、（これらのプロトコルが許可される）適切な暗号化（Data Encryption）レベルと認証を選択します。
Networking（呼び出される VPN サーバのタイプ）の基で PPTP を選択して、OK をクリックします。
ユーザ名とパスワードの確認中を示すウィンドウが表示されます。
ネットワークへのコンピュータの登録中を示すウィンドウが表示されます。
Connections Properties ウィンドウが表示されます。
下記のウィンドウに接続状態が表示されます。

確認

このセクションでは、設定が正しく動作していることを確認するために使用できる情報を提供しています。

アウトプットインタープリタツール（登録ユーザ専用）（OIT）は、特定の show コマンドをサポートします。OIT を使用して、show コマンドの出力の分析を表示します。

show debug：トラブルシューティングのために現在有効になっているdebugコマンドを表示します
show user：現在ログオンしているユーザとそのステータスを表示します
show ip route connected：ルーティングテーブルの現在の状態を表示します
show vpdn：アクティブなレイヤ2トンネルプロトコル(L2TP)またはレイヤ2転送(L2F)プロトコルトンネルに関する情報と、仮想プライベートダイヤルアップネットワーク(VPDN)のメッセージ識別子を表示します

show debug コマンドの出力例を次に示します。

2621#show debug
PPP:
  PPP authentication debugging is on
  PPP protocol negotiation debugging is on


VPN:
  VPDN events debugging is on
