RADIUSおよびTACACS+の認証とアカウンティング、およびある程度の許可は、PIXで終端するCisco Secure VPN Client 1.1およびCisco VPN 3000 2.5 Hardware Clientトンネルに対して行われます。認証、許可、アカウンティング(AAA)アクセスリストを含む以前のバージョンに対するPIX 5.2以降の拡張認証(Xauth)の変更。認証されたユーザがアクセスできるものを制御したり、Cisco VPN 3000 Client 2.5 Xauth終端をサポートしたりします。vpn group split-tunnelingコマンドにより、VPN 3000 Clientは、PIXの内側にあるネットワークだけでなく、他のネットワーク(インターネットなど)にも同時に接続できます。PIX 5.3以降では、以前のバージョンのコードに対するAAAの変更により、RADIUSポートが設定可能になりました。PIX 6.0では、VPN Client 3.xのサポートが追加されています。これには Diffie-Hellman グループ 2 が必要です。
このドキュメントに関する固有の要件はありません。
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。
PIX ソフトウェア リリース 5.2.1
Cisco Secure VPN Client 1.1
Cisco VPN 3000 2.5 Client または VPN Client 3.x
注:Cisco VPN Clientリリース3.0.xは、6.0より前のバージョンのPIXでは動作しません。詳細は、『IPSec/PPTP/L2TPをサポートするCiscoハードウェアとVPNクライアント』を参照してください。
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。
PIX ファイアウォール ソフトウェア リリース 6.2 では、Access Control List(ACL; アクセス コントロール リスト)を Access Control Server(ACS; アクセス コントロール サーバ)から PIX ファイアウォールへダウンロードする機能をサポートしています。これにより、AAAサーバでユーザごとのACLを設定して、ユーザごとのACL認可を提供できます。その後、ACSを介してPIXファイアウォールにダウンロードできます。この機能は、RADIUSサーバでのみサポートされます。TACACS+サーバではサポートされていません。
次のデバッグ手順を実行します。
AAA認証を追加する前に、PIX Xauth設定が機能することを確認します。
AAAを実装する前にトラフィックを渡すことができない場合、その後はトラフィックを渡すことができません。
PIX のいくつかのロギングを有効にします。
負荷の高いシステムではlogging console debuggingコマンドを発行しないでください。
logging buffered debuggingコマンドを発行できます。次に、show loggingコマンドを発行します。
ロギングは、システムメッセージログ(syslog)サーバに送信して確認することもできます。
TACACS+ サーバまたは RADIUS サーバでデバッグをオンにします。このオプションはすべてのサーバで有効です。
debug crypto ipsec sa:このデバッグコマンドはIPSecイベントを表示します。
debug crypto isakmp sa:このデバッグコマンドは、インターネットキーエクスチェンジ(IKE)イベントに関するメッセージを表示します。
debug crypto isakmp engine:このdebugコマンドは、IKEイベントに関するメッセージを表示します。
Cisco Secure 1.1またはVPN 3000 Client 2.5でクライアント側のデバッグを表示するために、ログビューアを有効にします。
user = noacl{ password = clear "********" service=shell { } } user = pixb{ password = clear "********" service=shell { set acl=115 } } user = 3000full{ password = clear "********" service=shell { } } user = 3000partial{ password = clear "********" service=shell { } }
Cisco Secure ACS for Windowsでは、noacl、3000full、および3000partialユーザに必要なのはユーザ名とパスワードだけです。pixbユーザには、ユーザ名、パスワード、チェックインされたグループのシェルまたはexec、チェックされたACL、およびボックス内の115が必要です。
user = noacl{ password = clear "********" } user = pixb{ password = clear "********" radius=Cisco { reply_attributes= { 9,1="acl=115" } } } user = 3000full{ password = clear "********" } user = 3000partial{ password = clear "********" }
Radius/Cisco はデバイス タイプです。Cisco Secure ACS for Windowsでは、noacl、3000full、および3000partialユーザに必要なのはユーザ名とパスワードだけです。pixbユーザには、ユーザ名、パスワード、およびチェックが必要で、Cisco/RADIUSの長方形のボックスに009\001 AV-Pair(ベンダー固有)と表示されているacl=115が必要です。
注:ACLのベンダー属性が必要です。アトリビュート 11、フィルター ID は無効です。この問題には、Cisco Bug ID CSCdt50422(登録ユーザ専用)が割り当てられています。この問題は、PIXソフトウェアリリース6.0.1で修正されています。
noacl Password= "noacl" pixb Password= "pixb" cisco-avpair = "acl=115" 3000full Password= "3000full" 3000partial Password= "3000partial"
一部の RADIUS サーバは、1645/1646 以外の RADIUS ポート(通常は 1812/1813)を使用します。PIX 5.3以降では、次のコマンドを使用して、RADIUS認証およびアカウンティングポートをデフォルトの1645/1646以外のポートに変更できます。
aaa-server radius-authport #
aaa-server radius-acctport #
この例では、3つのVPN ClientすべてがXauthで認証されます。ただし、スプリットトンネリングは使用されていないため、VPN ClientはPIX内部のネットワークにしかアクセスできません。スプリットトンネリングの詳細は、『VPNグループでXauthを認証する方法』を参照してください。AAAサーバから渡されたACLは、すべてのVPNクライアントに適用されます。この例の目標は、ユーザnoaclがPIX内部のすべてのリソースに接続して到達することです。ユーザpixbは接続しますが、ACL 115はXauthプロセス中にAAAサーバから渡されるため、ユーザは10.1.1.40のみに到達できます。10.1.1.41および内部の他のすべてのIPアドレスへのアクセスは拒否されます。
注:VPN Client 3.0をサポートするには、PIXソフトウェアリリース6.0が必要です。

この例では、VPN 3000 Client 2.5またはVPN Client 3.0がXauthで認証され、スプリットトンネリングが有効になります。VPNグループメンバーシップにより、ACLはPIXからVPN 3000 Clientに渡されます。暗号化されたトンネルを持つのはPIX内部のネットワークのみであることを指定します。その他のトラフィック(おそらくインターネットへのトラフィック)は暗号化されません。
この例では、グループvpn3000-all(PIX上)内の、ユーザ名が3000full(AAAサーバ上)の1つのVPN Clientが、インターネットと同時にPIX内の10.1.1.Xネットワーク全体にアクセスしています。VPN Clientは、wins-server、dns-server、およびdomain-nameの情報を受信します。グループvpn3000-41(PIX上)にあるユーザ名3000partial(AAAサーバ上)の他のVPN Clientは、グループプロファイルにより、ネットワーク内の1つのIPアドレス(10.1.1.40)にのみアクセスします。このVPN Clientはwinsサーバとdnsサーバの情報を受信しませんが、スプリットトンネリングは行います。
注:VPN Client 3.0をサポートするには、PIXソフトウェアリリース6.0が必要です。
次のステップを実行します。
注:VPN 2.5または3.0 Clientの設定は、関係するユーザによって異なります。
Options > Properties > Authentication の順に選択します。
グループ名とグループのパスワードが、VPN グループ vpn3000-all password ******** または VPN グループ vpn3000-41 password ******** のように、PIX 上のグループ名に一致します。ホスト名は 172.18.124.157 です。
[Connect] をクリックします。
xauth ウィンドウが表示されたら、AAA サーバの設定のいずれかと一致するユーザ名とパスワードを入力します。
この例では、ユーザ3000fullが認証されると、vpn3000-allグループから情報が選択されます。ユーザ3000partialがvpn3000-41グループから情報をピックアップします。ウィンドウに「Negotiating security profiles」および「Your link is now secure」と表示されます。
ユーザ3000fullは、グループvpn3000-allのパスワードを使用します。スプリットトンネリングの目的で、access-list 108がそのグループに関連付けられます。トンネルは10.1.1.xネットワークに対して形成されます。アクセスリスト108に含まれないデバイス(インターネットなど)へのトラフィックフローは暗号化されません。これはスプリットトンネリングです。
これは、ユーザ3000fullのVPN Client接続ステータスウィンドウの出力です。
Network Mask key 10.1.1.0 255.255.255.0 key 172.18.124.157 255.255.255.255
ユーザ3000partialはグループvpn3000-41のパスワードを使用します。スプリットトンネリングの目的で、access-list 125がそのグループに関連付けられます。トンネルは10.1.1.41デバイスに対して形成されます。アクセスリスト125に含まれないデバイス(インターネットなど)へのトラフィックフローは暗号化されません。ただし、トラフィックはルーティングできないため、トラフィックは10.1.1.40デバイスに流れません。暗号化トンネルのリストでは指定されていません。
これは、ユーザ3000partialのVPN Client接続ステータスウィンドウの出力です。
Network Mask key 10.1.1.41 255.255.255.255 key 172.18.124.157 255.255.255.255
注:Cisco Secure VPN Client 1.1は、Internet Security Association and Key Management Protocol(ISAKMP)キーがないため、この方法では動作しません。isakmp key ******** address 0.0.0.0 netmask 0.0.0.0コマンドを追加して、すべてのVPN Clientが機能するようにします。

VPN Client接続用にローカルXauthを設定するには、次のコマンドが必要です。
aaa-server server-tag protocol local(サーバータグプロトコルローカル)
crypto map map-name client authentication aaa-server-name
usernameコマンドを発行して、PIX上でローカルユーザを定義します。
ローカルのPIX Firewallユーザ認証データベースを使用するには、aaa-serverコマンドのserver-tagパラメータにLOCALを入力します。aaa-serverコマンドがcrypto mapコマンドとともに発行されて認証アソシエーションを確立すると、VPN ClientがPIX Firewallにアクセスする際に認証されます。
アカウンティングを追加するコマンドの構文を次に示します。
aaa accounting acctg_service|except inbound|outbound|if_name local_ip local_mask foreign_ip foreign_mask tacacs+|radius;
または(5.2の新機能):
aaa accounting include acctg_service inbound|outbound match server_tag
PIX設定で追加するコマンドは次のとおりです。
aaa accounting include any inbound 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 AuthInbound ;
または(5.2の新機能):
access-list 150 permit ip any any aaa accounting match 150 outside AuthInbound
注:Xauth アカウンティングが動作するためには、sysopt ipsec pl-compatible コマンドではなく sysopt connection permit-ipsec コマンドが必要です。Xauth アカウンティングは、sysopt ipsec pl-compatible コマンドだけでは動作しません。XauthアカウンティングはTCP接続に有効です。インターネット制御メッセージプロトコル(ICMP)またはユーザデータグラムプロトコル(UDP)では無効です。
