Windows 7からASA 5520へのL2TP / IPSec

9

私たちのASA5520でL2TP / IPSecをセットアップして、開発者の1人のフリンジケースをサポートしようとしています。組み込みのvpnサブシステムを使用すると、Windows VPNサブシステムはログイン用のkerberosまたはNTLM cookieを格納するように見え、Cisco VPNクライアントとAnyConnectクライアントはこれを行いません。

Windows 7経由でVPNに接続しようとすると、接続が失敗します。

具体的には、このエラーには関連性があると思い

ます。クラスカプセル化モードの属性タイプが一致しません：Rcv'd：UDP Transport Cfg'd：UDP Tunnel（NAT-T）

暗号化ドライバーからのデバッグはあまり役に立たないようです。以下はisakmpレベル127とipsecレベル100の場合です。

明らかに、フェーズ2の不一致は通常、提案を変更することで解決されますが、残念ながら、Windows 7では提案の設定をまったく変更できないようです。Win7構成でNAT-Tを明示的にオンにする方法はありません。

だから、私の質問はこうです：私の設定は厄介ですか？8.4がロードされたASA上のWindows 7でL2TPが正しく機能している人はいますか？

クライアントがグループ2 Diffie-Helmanを使用するように構成していないため、フェーズ1は失敗します。それでもサーバーはそれを必要とします。

Windows 7と8.3（2）13（FIPS認定）が適用されたASAの間で「LAN間」モードでIPSECが動作しています。

私はあなたがエラーに関して正しいと確信しています-それがSAをネゴシエートできない場合、あなたは夢中です。

「NAT Traversal」を解消してみます。もちろん、NATを超えようとするのに行き詰まっているかもしれませんが、その場合は必要になるかもしれません。しかし、それはあなたの問題の原因のように見えます。

あなたの他のオプションは、Windows 7でnat-traversal SAタイプを実行する方法を理解することです。あなたはnetsh advfirewall consec窓をぶらぶらと試すかもしれません。

これが私がブックマークしたそのリファレンスです。 http://technet.microsoft.com/en-us/library/dd736198(v=ws.10).aspx。

1つのメモ-Windowsのドキュメントでは、定期的に接続のキーを再設定することがいかに重要であるかについて多くのことが説明されています。ただし、再入力の頻度が高すぎる場合、ASAはダンプを取り、接続をドロップします。2分ごとよりも頻繁にキーを再入力しないようにしてください。キーの再生成にMSの推奨バイト数の値を使用すると、2分未満になります。

私たちがサポートケースを開いたとき、M $は彼らの推奨の真の理由を実際に与えることができませんでした。彼らは私たちに巨額の請求書を送った。

スタティックピアとダイナミックピアが同じクリプトマップで設定されている場合、クリプトマップエントリの順序は非常に重要です。ダイナミック暗号マップエントリのシーケンス番号は、他のすべてのスタティック暗号マップエントリよりも大きくする必要があります。
