目录


简介

点对点隧道协议(PPTP)支持被添加了到Cisco IOSï¿Â在Cisco 7100及7200路由器平台的½软件版本12.0.5.XE5。更多平台的支持在Cisco IOS软件版本12.1.5.T被添加了。

请求注释(RFC) 2637描述PPTP。即根据此RFC, PPTP访问集线器(PAC)是客户端(PC或呼叫方),并且PPTP网络服务器(PNS)是服务器(即呼叫的路由器或设备)。

先决条件

要求

本文假设,您设置对路由器的PPTP连接有本地微软询问握手认证协议V1验证(和或者使用这些文档,要求MS-CHAP V1)的Microsoft点对点加密[MPPE]的,并且他们已经工作。远程验证拨入用户服务(RADIUS)为MPPE加密支持要求;TACACS+工作为验证,但是不为MPPE密钥。

使用的组件

本文档中的信息基于以下软件和硬件版本。

  • Microsoft IAS可选组件在有活动目录的Microsoft 2000高级服务器安装。

  • 一个Cisco 3600路由器。

  • Cisco IOS软件版本c3640-io3s56i-mz.121-5.T。

此配置使用在Windows 2000 Advanced Server安装的Microsoft IAS作为RADIUS服务器。

本文档中的信息都是基于特定实验室环境中的设备创建的。本文档中使用的所有设备最初均采用原始(默认)配置。如果您是在真实网络上操作,请确保您在使用任何命令前已经了解其潜在影响。

规则

有关文档规则的详细信息,请参阅 Cisco 技术提示规则

背景理论

此配置示例展示如何设置PC连接到路由器(在地址10.200.20.2),然后验证用户对Microsoft的互联网认证服务器(IAS) (在10.200.20.245)在允许用户前到网络。PPTP支持是可用的与思科安全访问控制服务器(ACS)版本2.5为Windows。然而,它可能不与路由器一起使用由于Cisco Bug ID CSCds92266。如果使用Cisco Secure,我们推荐使用Cisco Secure版本2.6或以上。Cisco Secure UNIX不支持MPPE。与MPPE支持的其他两个RADIUS应用程序是Microsoft RADIUS和Funk RADIUS。

配置

本部分提供有关如何配置本文档所述功能的信息。

注意: 要查找本文档中使用的命令的其他相关信息,请使用 IOS 命令查找工具

网络图

本文档使用下图所示的网络设置。

/image/gif/paws/3885/pptp_3885.gif

拨号客户端的IP池:

  • 网关路由器:192.168.1.2 | 192.168.1.254

  • LNS :172.16.10.1 | 172.16.10.10

虽然上述设置使用一个拨号客户端连接到网络服务提供商(ISP)路由器通过拨号,您能通过所有媒体联络PC和网关路由器,例如LAN。

为 Microsoft IAS 配置 Windows 2000 Advanced Server

此部分显示如何配置Microsoft IAS的Windows 2000 Advanced Server :

  1. 确保安装了 Microsoft IAS。要安装Microsoft IAS,请登陆作为管理员。在网络服务下,确保清除所有复选框。选择Internet Authentication Server复选框然后点击OK键。

  2. 在“Windows 组件向导”中,单击下一步。如果出现提示,请插入 Windows 2000 CD。

  3. 在必需文件复制后请点击芬通社然后关上所有windows。您不需要重新启动。

配置 RADIUS 客户端

此部分显示步骤配置RADIUS客户端:

  1. 管理工具中,打开“Internet 身份验证服务器控制台”,然后单击“客户端”。

  2. 友好名称方框中,请键入网络接入服务器(NAS)的IP地址。

  3. 点击使用此IP选项

  4. 客户端供应商请丢弃下来列表框,保证RADIUS Standard选项选择。

  5. 共享共享的塞克雷确认秘密方框,键入密码然后单击芬通社

  6. 在控制台结构树中,在互联网认证服务的右键单击,然后单击开始

  7. 关闭控制台。

配置 IAS 上的用户

不同于Cisco Secure, Windows 2000 RADIUS用户数据库紧密绑定对Windows用户数据库。万一活动目录在您的Windows 2000服务器安装,请创建您从激活目录用户和计算机的新的拨号用户。如果活动目录没有安装,请使用本地用户和组管理工具创建新用户。

配置活动目录的用户

此部分显示步骤配置活动目录的用户:

  1. Active Directory 用户和计算机控制台中,展开您的域。用鼠标右键单击用户。移动选择新用户。创建一个名为 tac 的新用户。

  2. 键入在Password及Confirm Password对话框的一个密码。

  3. 清除用户必须在下个登录字段更改密码并且其次单击。

  4. 打开用户TAC属性框。切换至拨入选项卡。在远程访问权限(拨入或 VPN)下,单击“允许访问”,然后单击“确定”。

配置用户,如果活动目录没有安装

如果活动目录没有安装,此部分显示步骤配置用户:

  1. Administrative Tools部分,请点击计算机管理。展开计算机管理控制台,然后单击“本地用户和组”。用鼠标右键单击在用户滚动条选择新用户。创建一个名为 tac 的新用户。

  2. 键入在Password及Confirm Password对话框的一个密码。

  3. 清除用户下次登录时须更改密码选项,然后单击“下一步”。

  4. 打开新用户呼叫TAC的属性框。切换至拨入选项卡。在远程访问权限(拨入或 VPN)下,单击“允许访问”,然后单击“确定”。

将远程访问策略应用于 Windows 用户

此部分显示步骤运用Remote access Policy对Windows用户:

  1. 管理工具,请打开互联网验证服务器控制台并且点击Remote access Policy

  2. 点击Add按钮Specify the Conditions to Match,并且添加服务类型。选择可用的类型如成帧并且添加它到Selected Types列表。按确定。

  3. 单击“指定匹配条件”上的添加按钮,然后添加“帧协议”。选择可用的类型作为ppp并且添加它到Selected Types列表。按确定。

  4. 单击“指定匹配条件”上的添加按钮,然后添加“Windows 组”,以添加用户所属的 Windows 组。选择组并且添加它到所选类型并且按OK

  5. Allow Access if Dial-in Permission is Enabled属性,请选择批准远程接入

  6. 关闭控制台。

为 PPTP 配置 Windows 2000 客户端

下面的部分显示步骤配置PPTP的Windows 2000客户端:

  1. 开始菜单,请选择设置,然后:

    • 控制面板网络和拨号连接或者

    • 网络和拨号连接然后Make New Connection

    请使用向导创建呼叫PPTP的连接。此连接通过 Internet 连接到专用网络。您也需要指定PPTP网络服务器(PNS) IP地址或名称。

  2. 新连接显示在“控制面板”下的网络和拨号连接窗口中。

    从这里,请点击右边的鼠标按钮编辑其属性。在Networking选项下,请确保Type Of Server I Am Calling字段设置为PPTP。如果计划从网关分配对此客户端的一个动态内部地址,通过本地池或动态主机配置协议(DHCP),选择TCP/IP协议和确保客户端配置自动地获取IP地址。您可以自动地也发出DNS信息。

    高级按钮允许您定义静态Windows Internet Naming Service (WINS)和DNS信息。

    选项卡允许您关闭IPSec或分配一项不同的策略到连接。

  3. 安全选项卡下,您能定义用户验证参数。例如, PAP、CHAP或者MS-CHAP或者Windows登陆。一旦连接配置,您能双击对此显示登录画面然后连接。

配置

使用下列路由器配置,用户能连接用户名TAC和密码admin,即使RADIUS服务器不可用(这是可能的,当Microsoft IAS将配置)时。以下配置示例概述L2TP的required命令,不用IPSec。

验证

本部分所提供的信息可用于确认您的配置是否正常工作。

输出解释器工具支持某些 show 命令(只限于注册用户),通过它可以查看 show 命令输出的分析。

  • show vpdn -显示关于活动第2层转发(L2F)协议隧道和消息标识符的信息在VPDN。

您能也使用show vpdn ?看到其他特定VPDN的显示命令。

故障排除

本部分提供的信息可用于对配置进行故障排除。

故障排除命令

输出解释器工具支持某些 show 命令(只限于注册用户),通过它可以查看 show 命令输出的分析。

注意: 在发出 debug 命令之前,请参阅有关 Debug 命令的重要信息

  • debug aaa authentication -显示关于AAA/TACACS+验证的信息。

  • debug aaa authorization -显示关于AAA/TACACS+特权的信息。

  • debug ppp negotiation - 显示在 PPP 启动期间传输的 PPP 数据包,在此启动期间将协商 PPP 选项。

  • debug ppp authentication -显示认证协议消息,包括质询验证协议(CHAP)信息包交换和密码认证协议交换。

  • debug radius -显示详细的调试信息关联与RADIUS。如果验证工作,但是有与MPPE加密的问题,请使用其中一个下面调试指令。

  • debug ppp mppe packet -显示所有流入流出的MPPE流量。

  • debug ppp mppe event -显示关键MPPE出现。

  • debug ppp mppe detailed -显示冗长MPPE信息。

  • debug vpdn l2x-packets -显示关于L2F协议报头和状态的消息。

  • debug vpdn events -显示关于是正常隧道建立的一部分或关闭的事件的消息。

  • debug vpdn errors -显示防止一个通道设立造成一个已建隧道关闭的错误或错误。

  • debug vpdn packets -显示被交换的每个协议信息包。此选项可能会导致出现大量的调试消息,因此通常只应在具有单个活动会话的调试机箱中使用。

分割隧道

让我们假设网关路由器是ISP路由器。当PPTP通道在PC时出来, PPTP路由比上一个默认安装与高度量标准,因此我们丢失Internet连接。补救此,修改Microsoft路由删除默认和重新安装默认路由(这要求知道IP地址PPTP客户端分配;对于当前示例,这是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

如果客户端没有进行加密配置

在用于PPTP会话的拨号连接的安全选项卡下,您能定义用户验证参数。例如,这可以是PAP、CHAP、MS-CHAP或者Windows登陆。如果选择允许的不加密(服务器断开,如果要求加密)在VPN连接的Properties部分的选项,您可以发现在客户端的一PPTP错误消息:
