ASA 配置
ASA 配置概要
VPN 客户端配置

ASA 配置

要在 ASA 上安装第三方供应商数字证书，请执行下列步骤：

步骤1:验证Date、Time和Time Zone值是否准确
第二步：生成证书签名请求
第三步：验证信任点
第四步：安装证书
第五步：配置远程访问VPN (IPSec)以使用新安装的证书

步骤1:验证Date、Time和Time Zone值是否准确

ASDM 步骤

单击 Configuration，然后单击 Device Setup。
展开 System Time，然后选择 Clock。
验证列出的信息是否准确。

要正确通过证书验证，Date、Time 和 Time Zone 值必须准确。

命令行示例

CiscoASA
CiscoASA#show clock 05:37:37.904 UTC Fri Dec 21 2007

第二步：生成证书签名请求

要让第三方 CA 发放身份证书，需要提供证书签名请求 (CSR)。CSR 包含 ASA 的可分辨名称 (DN) 字符串与 ASA 的已生成公钥。ASA 将使用生成的私钥对 CSR 进行数字签名。

ASDM 步骤

单击 Configuration，然后单击 Device Management。
展开 Certificate Management，然后选择 Identity Certificates。
单击 Add。
单击 Add a new identity certificate 单选按钮。
对于 Key Pair，单击 New。
单击 Enter new key pair name 单选按钮。您必须明确指出密钥对名称以进行识别。
单击 Generate Now。

这将立即创建密钥对。

要定义 Certificate Subject DN，请单击 Select，然后配置下表中列出的属性：

属性	描述
CN	将用于连接防火墙的完全限定域名 (FQDN)。例如：CiscoASA.cisco.com
OU	部门名称
O	公司名称（请避免使用特殊字符）
C	国家/地区代码（不带标点的 2 位字母代码）
圣	州/省（必须拼写完整，例如：北卡罗来纳州）
L	城市

要配置这些值，可以从 Attribute 下拉列表中选择值或输入值，然后单击 Add。

注意：某些第三方供应商要求在颁发身份证书之前包含特定属性。如果不确定需要提供什么属性，请与您的供应商联系以了解详细信息。

添加相应的值之后，单击 OK。

将会出现 Add Identity Certificate 对话框，并显示已填入的 Certificate Subject DN。
单击 Advanced。
在 FQDN 字段中，输入要用于从 Internet 访问设备的 FQDN。

此值必须与用于公用名称 (CN) 的 FQDN 相同。
单击 OK，然后单击 Add Certificate。

系统会提示您将 CSR 保存到本地计算机上的文件中。
单击 Browse，选择用于保存 CSR 的位置，然后使用 .txt 扩展名保存文件。

注意：以.txt扩展名保存文件时，可以使用文本编辑器（如记事本）打开文件并查看PKCS#10请求。
将保存的 CSR 提交到第三方供应商（例如 Microsoft CA），如下所示。
1. 使用为 vpnserver 提供的用户凭证通过 Web 登录到 CA 服务器 172.16.5.1。
  
  注意：请确保您具有用于ASA （vpn服务器）的用户帐户和CA服务器。
2. 单击 Request a certificate > advanced certificate request，然后选择 Submit a certificate request by using a base-64-encoded CMC or PKCS#10 file or submit a renewal request by using a base-64-encoded PKCS#7 file。
3. 复制编码信息，并将其粘贴到 Saved Request 框中，然后单击 Submit。
4. 单击 Base 64 encoded 单选按钮，然后单击 Download certificate。
5. 将会出现 File Download 窗口。使用文件名 cert_client_id.cer 保存文件，这是要安装在 ASA 上的身份证书。

第三步：验证信任点

从第三方供应商处收到身份证书后，您可以继续执行此步骤。

ASDM 步骤

将身份证书保存到本地计算机中。
如果您收到的是非文件形式的 base64 加密证书，则您必须复制此 base64 信息，并将其粘贴到文本文件中。
将文件扩展名改为 .cer

注意：使用.cer扩展名重命名文件后，文件图标将显示为证书，如下所示。
双击此证书文件。

注意：如果General选项卡中显示Windows does not have enough information to verify this certificate消息，则在继续执行此步骤之前，您必须获取第三方供应商的根CA或中间CA证书。请与第三方供应商或 CA 管理员联系，以获得其发放的根 CA 或中间 CA 证书。
单击 Certificate Path 选项卡。
单击与所发放的身份证书关联的 CA 证书，然后单击 View Certificate。

将会出现 CA 证书的详细信息。
单击 Details 以查看身份证书的详细信息。
在安装身份证书之前，您必须从 CA 服务器中下载 CA 证书，并将其安装到 ASA 中，如下所示。

要从名为 CA1 的 CA 服务器中下载 CA 证书，请执行下列步骤。
1. 使用为 VPN 服务器提供的凭证通过 Web 登录到 CA 服务器 172.16.5.1。
2. 单击 Download a CA certificate, certificate chain or CRL 以打开如下所示的窗口。单击 Base64 单选按钮以选择其作为编码方法，然后单击 Download CA certificate。
3. 使用文件名 certnew.cer 将 CA 证书保存到计算机中。
浏览到 CA 证书的保存位置。
使用文本编辑器打开文件，例如记事本。右键单击文件，然后选择 Send To > Notepad。
将会显示类似于下图中证书的 base64 编码信息：
在 ASDM 中，单击 Configuration，然后单击 Device Management。
展开 Certificate Management，然后选择 CA Certificates。
单击 Add。
单击 Paste certificate in PEM Format 单选按钮，然后将第三方供应商提供的 base64 CA 证书粘贴到文本字段中。
单击 Install Certificate。

将会出现一个确认安装成功的对话框。

CiscoASA(config)#

第五步：配置远程访问VPN (IPSec)以使用新安装的证书

ASDM 步骤

执行下列步骤以配置远程访问 VPN：

选择 Configuration > Remote Access VPN > Network (Client) Access > Advanced > IPSec > IKE Policies > Add 以创建 ISAKMP 策略 65535，如下所示。

单击 OK，然后单击 Apply。
选择 Configuration > Remote Access VPN > Network (Client) Access > Advanced > IPSec > IPSec Transform Sets > Add 以创建 myset 转换集，如下所示。

单击 OK，然后单击 Apply。
选择 Configuration > Remote Access VPN > Network (Client) Access > Advanced > IPSec > Crypto Maps > Add 以使用优先级为 10 的动态策略创建加密映射，如下所示。

单击 OK，然后单击 Apply。

注意：ASA 8.0不支持SHA 2。此外，不支持使用具有256哈希值的证书的IPSec客户端。
选择 Configuration > Remote Access VPN > Network (Client) Access > Advanced > Group Policies > Add 以创建 Defaultgroup 组策略，如下所示。

单击 OK，然后单击 Apply。
选择 Configuration > Remote Access VPN > Network (Client) Access > Address Assignment > Address Pools > Add 以便为要动态指定的 VPN Client 用户配置 vpnpool 地址池。

单击 OK，然后单击 Apply。
选择 Configuration > Remote Access VPN > AAA Setup > Local Users > Add 以便为 VPN Client 访问创建 vpnuser 用户帐户。同时，将此用户设为 DefaultRAGroup 成员。
选择 Configuration > Remote Access VPN > Network (Client) Access > IPSec Connection Profiles > Edit 以编辑 DefaultRAGroup，如下所示。
- 从 IKE Peer Authentication 字段的下拉列表中选择相应的 identity certificate。
- 为 User Authentication 字段的 Server Group 选择 LOCAL。
- 为 Client Address Assignment 字段的 Client Address Pool 选择 vpnpool。
- 为 Default Group Policy 字段的 Group Policy 选择 defaultgroup。
单击 OK，然后单击 Apply。

VPN 客户端配置

执行下列步骤以配置 VPN 客户端。

选择 Start > Programs > Cisco Systems VPN Client > VPN Client 以启动 VPN Client 软件。
执行下列步骤，以便从名为 CA1 的 CA 服务器中下载 CA 证书，然后将其安装到 Cisco VPN Client 中。
1. 使用为 vpnuser 提供的凭证通过 Web 登录到 CA 服务器 172.16.5.1。
  
  注意：请确保您具有用于CA服务器的VPN客户端用户帐户。
2. 单击 Download a CA certificate, certificate chain or CRL 以打开如下所示的窗口。单击 Base64 单选按钮以选择其作为编码方法，然后单击 Download CA certificate。
3. 使用文件名 certnew.cer 将 CA 证书保存到计算机中。默认情况下，它将存储在 C:\Program Files\Cisco Systems\VPN Client 路径中。
4. 在 VPN Client 中，选择 Certificates tab > Import，然后单击 Import from File 单选按钮。单击 Browse 以便从存储位置 C:\Program Files\Cisco Systems\VPN Client 中导入 CA 证书，如下所示。
  
  单击 Import。将会出现一个导入成功窗口，如下所示。
  
  在 Certificates 选项卡中，将会出现 CA 证书 CA1，如下所示。
  
  注意：请确保选中Show CA/RA Certificates选项（如下所示），否则CA证书将不会出现在证书窗口中。
执行下列步骤以下载身份证书，并将其安装到 VPN Client 中。
1. 在 CA 服务器 CA1 中，选择 Request a Certificate > advanced certificate request > Create and submit a request to this CA 以注册身份证书。
  
  单击“Submit”。
2. 单击 Yes 以继续操作。
3. 单击 Install this certificate。
4. 单击 Yes 以继续操作。
5. 您必须收到证书已安装的消息，如下所示。
6. 退出然后重新启动 VPN Client，以使已安装的证书出现在 VPN Client 的证书选项卡中，如下所示。
在 Connection entries 选项卡中，单击 New 以创建连接项 vpnuser，如下所示。
- 在 Host 字段中输入远程对等体 IP 地址（可路由）。
- 单击 Certificate Authentication 单选按钮，然后从下拉列表中选择身份证书，如下所示。
- Click Save.
单击 Connect。
出现提示时，输入 xauth 的用户名和口令信息，然后单击 OK 以连接远程网络。
VPN Client 即会连接 ASA，如下所示。

故障排除

本部分提供了可用于对配置进行故障排除的信息。

以下是您可能会遇到的一些可能的错误：

错误：无法分析或验证导入的证书

在安装身份证书时，如果您不具有通过相关信任点验证的正确的中间或根 CA 证书验证，则可能会出现此错误。您必须删除此身份证书，然后使用正确的中间或根 CA 证书重新验证身份。请与您的第三方供应商联系以验证您收到的 CA 证书是否正确。
Certificate does not contain general purpose public key

当您尝试将身份证书安装到错误的信任点时，可能会出现此错误。这是因为您尝试安装无效的身份证书，或者与信任点关联的密钥对不匹配身份证书中包含的公钥。请发出 show crypto ca certificates trustpointname 命令以验证您是否将身份证书安装到正确的信任点。请查找以Associated Trustpoints开头的行：如果列出的信任点错误，请使用本文档中介绍的过程删除并重新安装适当的信任点。同时，请验证在生成 CSR 之后密钥对是否未更改。
错误：ASA/PIX。Sev=Warning/3 IKE/0xE3000081 Invalid remote certificate id:

如果您具有证书验证问题，则在 VPN Client 中可能会出现此错误信息。请在 ASA/PIX 配置中使用 crypto isakmp identity auto 命令以解决此问题。
