網路圖表

本檔案會使用以下網路設定：

l2tp_3886.gif

本檔案將以下IP池用於撥號使用者端：

  • 網關路由器：192.168.1.2 ~ 192.168.1.254

  • LNS :172.16.10.1 ~ 172.16.10.1

為Microsoft IAS配置Windows 2000高級伺服器

確保已安裝Microsoft IAS。要安裝Microsoft IAS，請以管理員身份登入並完成以下步驟：

  1. 在Network Services下，驗證是否已清除所有覈取方塊。

  2. 選中Internet Authentication Server(IAS)覈取方塊，然後按一下OK。

  3. 在「Windows元件」嚮導中，按一下下一步。如果出現提示，請插入Windows 2000 CD。

  4. 複製所需檔案後，按一下完成，然後關閉所有視窗。您無需重新啟動。

設定RADIUS使用者端

請完成以下步驟：

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

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

  3. 按一下「Use This IP」。

  4. 在「Client-Vendor」下拉式清單中，確保選擇「RADIUS Standard」。

  5. 在Shared Secret和Confirm Shared Secret框中，輸入密碼，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CiscoSecure不同，Windows 2000遠端身份驗證撥入使用者伺服器(RADIUS)使用者資料庫與Windows使用者資料庫緊密繫結。

  • 如果在Windows 2000伺服器上安裝了Active Directory，請從Active Directory使用者和電腦建立新撥號使用者。

  • 如果尚未安裝Active Directory，則可以使用管理工具中的本地使用者和組來建立新使用者。

在Active Directory中配置使用者

完成以下步驟，以便使用Active Directory配置使用者：

  1. 在「Active Directory Users and Computers」控制檯中，展開域。

  2. 按一下右鍵Users Scroll以選擇New User。

  3. 建立一個名為tac的新使用者。

  4. 在Password和Confirm Password對話方塊中輸入您的密碼。

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

  6. 開啟使用者tac的屬性框。切換到Dial-in頁籤。

  7. 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）

完成以下步驟，在未安裝Active Directory的情況下配置使用者：

  1. 在Administrative Tools中，按一下Computer Management。

  2. 展開Computer Management控制檯，然後按一下Local Users and Groups。

  3. 按一下右鍵Users Scroll以選擇New User。

  4. 在密碼和確認密碼對話方塊中輸入密碼。

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

  6. 開啟新使用者tac的屬性框。切換到Dial-in頁籤。

  7. 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

完成以下步驟以應用遠端訪問策略：

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

  2. 按一下Specify the Conditions to Match上的Add按鈕並新增Service-type。選擇可用型別作為Framed。將其新增到所選型別，然後按確定。

  3. 按一下Specify the Conditions to Match上的Add按鈕並新增Framed Protocol。選擇可用型別為PPP。將其新增到所選型別，然後按確定。

  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。選擇組並將其新增到所選型別。按OK。

  5. 在Allow Access if Dial-in Permission is Enabled Properties上，選擇Grant Remote Access Permission。

  6. 關閉控制檯。

為L2TP配置Windows 2000客戶端

完成以下步驟，以便為L2TP配置Windows 2000客戶端：

  1. 在Start Menu中選擇Settings，然後執行以下路徑之一：

    • 控制面板>網路和撥號連線

    或

    • 網路和撥號連線> 新建連線

  2. 使用嚮導建立名為L2TP的連線。此連線通過Internet連線到專用網路。您還需要指定L2TP隧道網關的IP地址或名稱。

  3. 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，按一下右鍵編輯屬性。

  4. 在Networking頁籤下，確保Type Of Server I Am Calling設定為L2TP。

  5. 如果計畫通過本地池或DHCP從網關為此客戶端分配動態內部地址，請選擇TCP/IP協定。確保將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。

    • 在安全頁籤下，您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。

  6. 配置連線後，您可以按兩下該連線以啟動登入螢幕，然後點選連線。

為Windows 2000客戶端禁用IPSec

  1. 編輯剛建立的撥號連線L2TP的屬性。按一下右鍵新連線L2TP以獲取L2TP Properties視窗。

  2. 在「Networking」頁籤下，按一下「Internet Protocol(TCP/IP)properties」。按兩下Advanced頁籤。轉到選項索引標籤，按一下IP安全性屬性，如果選擇Do not use IPSEC，請將其雙重檢查。

注意：Microsoft Windows 2000客戶端具有預設遠端訪問和策略代理服務，預設情況下會為L2TP流量建立策略。此預設策略不允許沒有IPSec和加密的L2TP流量。您可以通過編輯Microsoft客戶端登錄檔編輯器來禁用Microsoft預設行為。本節提供了編輯Windows登錄檔和為L2TP流量禁用IPSec預設策略的過程。有關編輯Windows登錄檔的資訊，請參閱Microsoft文檔。

使用登錄檔編輯器(Regedt32.exe)新增新的登錄檔項以禁用IPSec。有關詳細資訊，請參閱Microsoft的文檔或Regedt32.exe的Microsoft幫助主題。

您必須將ProhibitIpSec登錄檔值新增到L2TP或IPSec連線的每個基於Windows 2000的終端電腦，以防止建立L2TP和IPSec流量的自動過濾器。當ProhibitIpSec登錄檔值設定為1時，基於Windows 2000的電腦不會建立使用CA身份驗證的自動過濾器。而是檢查本地或Active Directory IPSec策略。若要將ProhibitIpSec登錄檔值新增到基於Windows 2000的電腦，請使用Regedt32.exe在登錄檔中查詢此項： 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Rasman\Parameters

將此登錄檔值新增到此項： 

Value Name: ProhibitIpSec
Data Type: REG_DWORD
Value: 1

注意：要使更改生效，必須重新啟動基於Windows 2000的電腦。有關詳細資訊，請參閱以下Microsoft文章：

  • Q258261 — 禁用用於L2TP的IPSEC策略

  • Q240262 — 如何使用預共用金鑰配置L2TP/IPSec連線

配置Cisco IOS for L2TP

這些配置概括了沒有IPSec的L2TP所需的命令。此基本配置工作正常後，您還可以配置IPSec。

debug和show命令

使用 debug 指令之前，請先參閱有關 Debug 指令的重要資訊。

輸出直譯器工具(僅供已註冊客戶使用)(OIT)支援某些show命令。使用OIT檢視show命令輸出的分析。

如果操作失敗，則最小的debug命令包括：

  • 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，其中協商了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。

如果驗證有效，但Microsoft點對點加密(MPPE)加密出現問題，請使用以下命令之一：

  • 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2級轉發(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 — 顯示阻止隧道建立的錯誤或導致已建立的隧道關閉的錯誤。

  • 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。

  • show vpdn — 顯示有關虛擬專用撥接網路(VPDN)中作用中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 ?命令檢視其他vpdn特定的show命令。

分割通道

假設網關路由器是Internet服務提供商(ISP)路由器。當PC上啟動點對點通道通訊協定(PPTP)通道時，PPTP路由所安裝的度量高於之前的預設值，因此會失去網際網路連線。為了解決此問題，請修改Microsoft路由以刪除預設路由並重新安裝預設路由(需要知道分配了PPTP客戶端的IP地址；目前的範例為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

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

問題1:未禁用IPSec

症狀

PC使用者看到以下消息： 

Error connecting to L2TP:
Error 781: The encryption attempt failed because 
no valid certificate was found.

解決方案

轉到Virtual Private Connection視窗的Properties部分，然後按一下Security頁籤。禁用Require Data Encryption選項。

問題2:錯誤789

症狀

L2TP連線嘗試失敗，因為安全層在與遠端電腦的初始協商期間遇到處理錯誤。

由於L2TP不提供加密，因此Microsoft遠端訪問和策略代理服務會建立用於L2TP流量的策略。這適用於Microsoft Windows 2000 Advanced Server、Microsoft Windows 2000 Server和Microsoft Windows 2000 Professional。

解決方案

使用登錄檔編輯器(Regedt32.exe)新增新的登錄檔項以禁用IPSec。有關Regedt32.exe，請參閱Microsoft文檔或Microsoft幫助主題。

您必須將ProhibitIpSec登錄檔值新增到L2TP或IPSec連線的每個基於Windows 2000的終端電腦，以防止建立L2TP和IPSec流量的自動過濾器。當ProhibitIpSec登錄檔值設定為1時，基於Windows 2000的電腦不會建立使用CA身份驗證的自動過濾器。而是檢查本地或Active Directory IPSec策略。若要將ProhibitIpSec登錄檔值新增到基於Windows 2000的電腦，請使用Regedt32.exe在登錄檔中查詢此項： 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Rasman\Parameters

將此登錄檔值新增到此項： 

Value Name: ProhibitIpSec
Data Type: REG_DWORD
Value: 1

注意：要使更改生效，必須重新啟動基於Windows 2000的電腦。

問題3:通道驗證問題

建立通道之前，使用者在NAS或LNS進行驗證。客戶端啟動的隧道（如來自Microsoft客戶端的L2TP）不需要此功能。

PC使用者看到以下消息：
