SSL VPN客户端接入失败经验案例

一、   组网:

客户端通过https协议访问SSL VPN网关的用户登录页面,并完成认证操作。组网图略。

 

二、   问题描述:

H3C SSL VPN支持WEBTCPIP三种接入方式,其中TCPIP接入方式需要安装ActiveX控件、虚网卡及下载客户端。ActiveX控件和客户端会对系统的注册表及Hosts文件等进行操作。鉴于这种应用方式涉及到客户端操作系统的安全设置、软件安装情况等因素,所以在使用过程中会出现一些接入不成功的情况。本案例就目前已知的部分SSL VPN客户端接入失败的情况进行总结并给出相应的解决方案。

 

三、   过程分析:

目前已知的错误情况主要有以下几类:

1.配置问题

1.1配置了IP主机资源并授权给用户,但是无相应的IP全局配置。

1.2 Autohome特性采用IP接入方式,但是没有给用户进行IP资源授权。

1.3 IP全局配置中地址池地址和客户本地地址冲突。

1.4 SSL VPN网关地址包含在授权给用户的IP主机资源地址或网段中。

2.版本升级兼容问题

2.1 老版本ActiveX控件和新版本客户端配合有问题。

3.客户端环境问题

3.1 安装ActiveX控件失败导致下载客户端软件失败,原因可能有:

1) 浏览器禁止安装或运行ActiveX控件。

2) 浏览器禁止已经安装的SSL VPN ActiveX控件。

3) 运行64位浏览器时,无法安装ActiveX控件。

4) IE7/IE8启用了保护模式,但是没有把SSL VPN网关地址加入受信任站点。

5) 客户操作系统安装的防火墙及杀毒软件禁止安装ActiveX控件或或者禁止ActiveX控件修改注册表导致下载客户端失败。

6) 操作系统缺少某些组件或补丁导致安装ActiveX失败。

4.虚网卡相关

4.1 安装虚网卡失败。

4.2 XP/Server 2003系统下,虚网卡安装成功,但是不主动发起DHCP请求,导致分配地址失败。

4.3 客户操作系统安装的防火墙及杀毒软件等阻止客户端软件修改主机路由或者Hosts文件。

5.DNS解析相关问题

5.1 PC加入域后,通过虚网卡转发的DNS请求无法自动补充待解析域名,导致解析失败。

5.2 待访问IP资源是域名方式访问时,本地网卡的DNSSSL VPN下发的DNS的解析顺序无法保证,导致解析失败

 

四、   问题现象及解决方法:

1.客户端接入正常。

正常情况下用户客户端可以正常启动,对于IP接入方式可以正常安装虚网卡,并且虚网卡成功分配到地址和添加相应的路由,用户业务访问正常。

1.1设备管理器中可以看到虚网卡。

                                                                                                           图1 设备管理器中有虚网卡

1.2用户成功分配虚地址和添加路由。

                                                                                             图2 登录SSL VPN后虚网卡成功分到地址

                                                                                                   图3 登录SSL VPN后成功添加路由

1.3成功日志信息。

成功日志信息分为不启用“只允许访问VPN”和启用“只允许访问VPN”两种情况:

1)  未使能 “IP网络->全局配置”中“只允许访问VPN” 。

5.3 解决方案。

有两种方法可以解决该问题:

1)  启用“资源管理->IP网络->全局配置”中“只允许访问VPN”选项,用户登录后系统会自动添加到SSL VPN网关的主机路由:

                                                                                          图11 启用“只访问VPN”选项下的路由信息

2)  修改IP资源,将SSL VPN网关地址排除在授权IP资源网段之外。

 

6.老版本ActiveX控件和新版本客户端配合问题。

6.1 页面错误提示信息。

                                                                                            图12 ActiveX控件版本和客户端版本不兼容

如果选择否,那么会出现启动IP客户端接入失败。

6.2 解决方案。

登录之前删除已经存在的客户端软件或者出现上述提示时选择“是”。

 

7.IE的管理加载项中将ActiveX控件禁用。

7.1 错误配置。

已经安装了SSL VPN ActiveX控件,但是IE的管理加载项中禁用控件。

                                                                                                    图13 禁用SSL VPN ActiveX控件

7.2 页面错误提示信息。

用户登录时会提示没有安装ActiveX控件,点击“取消”后,一直停留在主机检测页面:

                                                                                           图16 点击“取消”后无法安装ActiveX控件

7.3 解决方案。

启用IE的管理加载项中的ActiveX控件。

 

8IE安全选项中禁止运行ActiveX控件和插件。

8.1 错误配置。

                                                                                                         图17 禁止ActiveX控件配置

8.2 页面错误提示信息。

                                                                                                                 图18 页面错误提示

8.3 解决方案。

启用IE安全选项中“运行ActiveX 控件和插件”。

 

9.运行64位浏览器时无法安装ActiveX控件。

9.1 页面错误提示信息。

运行64位浏览器时,无法安装ActiveX控件,页面一直停留在验证ActiveX控件阶段。

                                                                                                       图19 不提示安装ActiveX控件

9.2 解决方案。

运行32位浏览器。

 

10.IE7/IE8启用了保护模式,但是SSL VPN网关地址非受信任站点。

10.1 页面错误提示信息。

根据用户是否安装ActiveX控件,是否有客户端,有如下3种错误提示信息:

1)  用户首次登录,没有安装ActiveX控件。

点击“确定”后,有下面提示:

点击“确定”,弹出下面提示:

2)  用户已经成功安装ActiveX控件:

用户登录后,弹出下面提示信息:

点击“确定”,弹出下面提示信息:

点击“确定”,弹出下面提示信息:

3)  已经安装ActiveX控件,并且有客户端文件,用户登录后提示如下信息:

10.2 解决方案。

取消IE浏览器的保护模式,或者将SSL VPN网关地址添加到浏览器受信任站点中。

 

11.操作系统缺少某些组件或补丁导致安装ActiveX失败

11.1 错误提示信息。

提示安装ActiveX控件,但是点击安装后,出现提示信息“安装ActiveX控件失败”。

手动安装ActiveX控件,出现错误提示信息“注册ActiveX控件失败”。在运行中运行“regsvr32 vpnactx.dll”,系统返回0x8007007e错误码。

11.2 解决方案。

Activex控件的注册安装需要系统的一些组件(.dll)预先安装注册好,如果系统中这些文件不存在或被损坏或者是没有注册,则会导致ActiveX控件安装失败。上述错误是由于在系统中缺少必要的组件,导致不能安装其他的ActiveX文件。解决方案如下:

1)  SSL VPN登录首页下载ActiveX控件安装文件。

2)  在“开始->运行”里输入: regsvr32 atl.dll 回车, 如果显示成功,再运行3)

3)  点击ActiveX控件安装包里的setup.exe

如果运行 regsvr32 atl.dll 不成功,请参考如下步骤解决:

1)  检查Windows系统目录(system32目录)中是否存在如下三个文件: msvcp60.dll,mfc42.dll, msvcrt.dll 文件, 如果不存在,请从网上下载或者从其他机器复制。

2)  检查系统目录(system32目录)中是否存在 atl.dll 文件, 如果不存在, 请从网上下载或者从其他机器复制。然后在“开始->运行”运行如下命令: regsvr32 atl.dll

3)  再次手动安装SSL VPN ActiveX控件。

一段时间后出现如下错误提示:

 

                                                                                                                 图20 错误提示信息

 

12.2 系统中无虚网卡相关信息。

                                                                                                       图21 异常情况下无虚网卡信息

                                                                                                         图22 异常情况下虚网卡信息

用户再次登录,日志中仍然出现上述安装信息。

12.3 解决方案。

上述问题出现的原因是由于系统缺陷引起,系统无法安装任何第三方虚网卡。暂无解决方案,建议重装系统。

 

13.XP/Server 2003系统下,虚网卡安装成功,但是不主动发起DHCP请求,导致分配地址失败。

13.4 解决方案。

“媒介感知”功能:windows 2000后的系统缺省具有media sense功能,当网线拔掉后,此网口上绑定的tcp/ip协议会自动卸掉,而此功能禁调后,无论网线插拔,网卡上绑定的tcp/ip协议都不会自动卸掉,同时不会发起dhcp请求。

修改注册表中下面一项的值:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

名为DisableDHCPMediaSense,类型为DWORD,取值为0

 

14.客户操作系统安装的防火墙及杀毒软件等阻止客户端软件修改主机路由或者Hosts文件。

防火墙的安全级别设置较高后,可能会禁止第三方程序修改注册表,修改 host文件等操作,导致客户端无法添加路由或修改Hosts文件,从而导致访问异常。

……

14.2 解决方案。

SSL VPN客户端添加到防火墙信任程序列表中。

 

15.待访问IP资源是域名方式访问时,本地网卡的DNSSSL VPN下发的DNS的解析顺序无法保证,导致解析失败。

15.1 错误现象。

访问IP资源时打开公网其他页面。

15.2 解决方案。

将待访问的IP资源对应的域名添加到预置域名配置中。
