簡介

在Cisco 7100和7200路由器平台上的Cisco IOS®軟體版本12.0.5.XE5中新增了點對點隧道協定(PPTP)支援。Cisco IOS軟體版本12.1.5.T新增了對更多平台的支援。

要求建議(RFC)2637描述了PPTP。根據此RFC，PPTP訪問集中器(PAC)是客戶端（即PC或呼叫者），PPTP網路伺服器(PNS)是伺服器（即被呼叫的路由器或裝置）。

必要條件

需求

本文檔假定您已使用這些文檔設定與路由器的PPTP連線，並且它們已在運行。該路由器具有本地Microsoft質詢握手身份驗證協定(MS-CHAP)V1身份驗證（以及可選的Microsoft點對點加密[MPPE]，需要MS-CHAP V1）。MPPE加密支援需要遠端身份驗證撥入使用者服務(RADIUS);TACACS+適用於驗證，但不適用於MPPE金鑰。

採用元件

本檔案中的資訊是根據以下軟體和硬體版本。

  • Microsoft IAS可選元件安裝在帶有Active Directory的Microsoft 2000高級伺服器上。

  • Cisco 3600路由器。

  • Cisco IOS軟體版本c3640-io3s56i-mz.121-5.T。

此配置使用安裝在Windows 2000高級伺服器上的Microsoft IAS作為RADIUS伺服器。

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您在即時網路中工作，請確保在使用任何命令之前瞭解其潛在影響。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景理論

此示例配置演示如何設定PC以連線到路由器（地址為10.200.20.2），然後路由器在允許使用者進入網路之前向Microsoft的Internet身份驗證伺服器(IAS)（地址為10.200.20.245）驗證使用者的身份。適用於Windows的Cisco安全存取控制伺服器(ACS)版本2.5提供PPTP支援。但是，由於Cisco錯誤ID CSCds92266，它可能對路由器無效。如果您使用的是Cisco Secure，我們建議使用Cisco Secure 2.6版或更高版本。Cisco Secure UNIX不支援MPPE。另外兩個支援MPPE的RADIUS應用程式是Microsoft RADIUS和Funk RADIUS。

設定

本節提供用於設定本文件中所述功能的資訊。

注意：要查詢有關本文檔中使用的命令的其他資訊，請使用IOS命令查詢工具

網路圖表

本文檔使用下圖所示的網路設定。

pptp_3885.gif

用於撥號客戶端的IP池：

  • 網關路由器：192.168.1.2 ~ 192.168.1.254

  • LNS:172.16.10.1 ~ 172.16.10.10

雖然上述設定使用撥號客戶端通過撥號連線到網際網路服務提供商(ISP)路由器，但您可以通過任何介質（例如LAN）連線PC和網關路由器。

為Microsoft IAS配置Windows 2000高級伺服器

本節介紹如何為Microsoft IAS配置Windows 2000高級伺服器：

  1. 確保已安裝Microsoft IAS。要安裝Microsoft IAS，請以管理員身份登入。在Network Services下，驗證是否已清除所有覈取方塊。選中Internet Authentication Server覈取方塊，然後按一下OK。

  2. 在「Windows Components(Windows元件)」嚮導中，按一下「Next（下一步）」。如果出現提示，請插入Windows 2000 CD。

  3. 複製所需檔案後，按一下Finish，然後關閉所有視窗。您無需重新啟動。

設定Radius使用者端

本節介紹設定radius使用者端的步驟：

  1. 在管理工具中，開啟Internet Authentication Server控制檯，然後按一下Clients。

  2. 在「Friendly Name」框中，鍵入網路訪問伺服器(NAS)的IP地址。

  3. 按一下Use this IP選項。

  4. 在「Client-Vendor」下拉選單框中，確保選中「RADIUS Standard」選項。

  5. 在Shared Secret和Confirm Shared Secret框中，鍵入密碼，然後按一下Finish。

  6. 在控制檯樹中，按一下右鍵Internet Authentication Service，然後按一下Start。

  7. 關閉控制檯。

在IAS上配置使用者

與Cisco Secure不同，Windows 2000 RADIUS使用者資料庫與Windows使用者資料庫緊密繫結。如果Active Directory安裝在Windows 2000伺服器上，請從Active Directory使用者和電腦建立新撥號使用者。如果未安裝Active Directory，請使用Local Users and Groups from Administrative tools來建立新使用者。

在Active Directory中配置使用者

本節介紹在Active Directory中配置使用者的步驟：

  1. 在「Active Directory Users and Computers」控制檯中，展開域。按一下右鍵Users。滾動選擇New User。建立一個名為tac的新使用者。

  2. 在Password和Confirm Password對話方塊中鍵入密碼。

  3. 清除User Must Change Password at Next Logon欄位，然後按一下Next。

  4. 開啟使用者tac屬性框。切換到Dial-In頁籤。在Remote Access Permission(Dial-in or VPN)下，按一下Allow Access，然後按一下OK。

配置使用者（如果未安裝Active Directory）

本節介紹在沒有安裝Active Directory的情況下配置使用者的步驟：

  1. 在Administrative Tools部分，按一下Computer Management。展開Computer Management控制檯，然後按一下Local Users and Groups。按一下右鍵Users捲軸以選擇New User。建立一個名為tac的新使用者。

  2. 在Password和Confirm Password對話方塊中鍵入密碼。

  3. 清除User Must Change Password at Next Logon選項，然後按一下Next。

  4. 開啟名為tac的屬性的新用戶框。切換到Dial-in頁籤。在Remote Access Permission(Dial-in or VPN)下，按一下Allow Access，然後按一下OK。

將遠端訪問策略應用於Windows使用者

本節介紹將遠端訪問策略應用於Windows使用者的步驟：

  1. 在Administrative Tools中，開啟Internet Authentication Server Console，然後按一下Remote Access Policies。

  2. 按一下Specify the Conditions to Match上的Add按鈕，然後新增Service-Type。選擇可用型別Framed，並將其新增到Selected Types清單。按OK。

  3. 按一下Specify the Conditions to Match上的Add按鈕並新增Framed Protocol。選擇可用型別作為ppp，並將其新增到Selected Types清單。按OK。

  4. 按一下Specify the Conditions to Match上的Add按鈕並新增Windows-Groups，以新增使用者所屬的Windows組。選擇該組並將其新增到Selected Types中，然後按OK。

  5. 在Allow Access if Dial-in Permission is Enabled屬性中，選擇Grant remote Access permission。

  6. 關閉控制檯。

為PPTP配置Windows 2000客戶端

以下部分顯示為PPTP配置Windows 2000客戶端的步驟：

  1. 在「Start」選單中選擇「Settings」 ，然後選擇：

    • 控制面板和網路和撥號連線，或

    • 然後建立網路和撥號連線。

    使用嚮導建立名為PPTP的連線。此連線通過Internet連線到專用網路。您還需要指定PPTP網路伺服器(PNS)IP地址或名稱。

  2. 新連線出現在「Control Panel（控制面板）」下的「Network and Dial-up Connections（網路和撥號連線）」視窗中。

    在此處，按一下右鍵可編輯其屬性。在Networking頁籤下，確保Type of Server I Am Calling欄位設定為PPTP。如果計畫通過本地池或動態主機配置協定(DHCP)從網關為此客戶端分配動態內部地址，請選擇TCP/IP協定，並確保客戶端配置為自動獲取IP地址。您也可以自動發出DNS資訊。

    Advanced按鈕允許您定義靜態Windows Internet命名服務(WINS)和DNS資訊。

    Options頁籤允許您關閉IPSec或為連線分配不同的策略。

  3. 在Security頁籤下，可以定義使用者身份驗證引數。例如，PAP、CHAP或MS-CHAP或Windows域登入。配置連線後，您可以按兩下它以顯示登入螢幕，然後進行連線。

組態

使用下列路由器配置，即使RADIUS伺服器不可用（在尚未配置Microsoft IAS時，這是可能的），使用者也能夠使用使用者名稱tac和密碼admin進行連線。 以下示例配置概述了不帶IPSec的L2tp所需的命令。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

輸出直譯器工具支援某些show命令，該工具允許您檢視show命令輸出的分析。

  • show vpdn — 顯示VPDN中有關作用中第2層轉送(L2F)通訊協定通道和訊息識別符號的資訊。

您還可以使用show vpdn ?檢視其他VPDN特定的show命令。

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

疑難排解指令

輸出直譯器工具支援某些show命令，該工具允許您檢視show命令輸出的分析。

注意：發出debug指令之前，請先參閱有關Debug指令的重要資訊。

  • debug aaa authentication — 顯示有關AAA/TACACS+身份驗證的資訊。

  • debug aaa authorization — 顯示有關AAA/TACACS+授權的資訊。

  • debug ppp negotiation — 顯示在PPP啟動期間傳輸的PPP資料包，其中會協商PPP選項。

  • debug ppp authentication — 顯示身份驗證協定消息，包括質詢身份驗證協定(CHAP)資料包交換和密碼身份驗證協定(PAP)交換。

  • debug radius — 顯示與RADIUS關聯的詳細調試資訊。如果身份驗證有效，但MPPE加密出現問題，請使用以下其中一個debug命令。

  • debug ppp mppe packet — 顯示所有傳入傳出MPPE流量。

  • debug ppp mppe event — 顯示關鍵MPPE事件。

  • debug ppp mppe detailed — 顯示詳細的MPPE資訊。

  • debug vpdn l2x-packets — 顯示有關L2F協定標頭和狀態的消息。

  • debug vpdn events — 顯示有關屬於正常隧道建立或關閉一部分的事件的消息。

  • debug vpdn errors — 顯示阻止建立通道的錯誤或導致關閉已建立通道的錯誤。

  • debug vpdn packets — 顯示交換的每個協定資料包。此選項可能導致大量調試消息，通常只能在具有單個活動會話的調試機箱上使用。

分割通道

假設網關路由器是ISP路由器。當PC上出現PPTP隧道時，PPTP路由的度量高於以前的預設值，因此會丟失Internet連線。要解決此問題，請修改Microsoft路由以刪除預設路由並重新安裝預設路由(這需要知道已分配PPTP客戶端的IP地址；當前範例為172.16.10.1): 

route delete 0.0.0.0
route add 0.0.0.0 mask 0.0.0.0 192.168.1.47 metric 1
route add 172.16.10.1 mask 255.255.255.0 192.168.1.47 metric 1

如果客戶端未配置加密

在用於PPTP會話的撥號連線的Security頁籤下，可以定義使用者身份驗證引數。例如，可以是PAP、CHAP、MS-CHAP或Windows域登入。如果您在VPN連線的屬性部分中選擇了No Encryption Allowed（如果伺服器要求加密，則斷開連線）選項，則可能會在客戶端上看到PPTP錯誤消息：
