通过FMC使用AAA/RADIUS身份验证配置远程访问VPN

有关分步操作步骤，请参阅本文档和此视频：

FTD CLI上的远程访问VPN配置为：

配置以在FMC上使用授权服务器

导航到Devices > Remote Access，然后选择所需的远程访问VPN策略。导航到Advanced > Address Assignment Policy，并确保启用选项Use authorization server（仅适用于RADIUS或领域）。

Enable Authorisation Server

在ISE上配置授权策略（RADIUS服务器）

步骤1.登录到ISE服务器并导航到管理>网络资源>网络设备。

TZ_Static_IP_Address_RADIUS_Authorization_16

步骤2.在Network Devices部分，点击Add，以便ISE可以处理来自FTD的RADIUS访问请求。

TZ_Static_IP_Address_RADIUS_Authorization_17

输入网络设备名称和IP地址字段，然后选中RADIUS身份验证设置框。共享密钥必须与在FMC上创建RADIUS服务器对象时使用的值相同。

TZ_Static_IP_Address_RADIUS_Authorization_18

使用此页面末尾的按钮保存它。

步骤3.导航到管理>身份管理>身份。

TZ_Static_IP_Address_RADIUS_Authorization_19

第4步：在Network Access Users部分，点击Add以便在ISE本地数据库中创建user1。

TZ_Static_IP_Address_RADIUS_Authorization_20

在Name和Login Password字段中输入用户名和密码，然后单击Submit。

TZ_Static_IP_Address_RADIUS_Authorization_21

步骤5.重复上述步骤以创建user2。

TZ_Static_IP_Address_RADIUS_Authorization_22

第 6 步：导航至策略 > 策略集。

TZ_Static_IP_Address_RADIUS_Authorization_23

步骤7.单击屏幕右侧的箭头>。

TZ_Static_IP_Address_RADIUS_Authorization_24

步骤8.点击Authorization Policy旁的箭头>以展开该策略。现在，单击+符号以添加新规则。

TZ_Static_IP_Address_RADIUS_Authorization_25

为规则提供名称，并在条件列下选择+符号。

TZ_Static_IP_Address_RADIUS_Authorization_26

单击“属性编辑器”(Attribute Editor)文本框并单击主题图标。向下滚动，直到找到RADIUS User-Name属性并选择它。

TZ_Static_IP_Address_RADIUS_Authorization_27

将Equals保留为运算符，并在其旁边的文本框中输入user1。单击Use以保存属性。

TZ_Static_IP_Address_RADIUS_Authorization_28

现在已设置此规则的条件。

步骤9.在结果/配置文件列中，单击+符号并选择创建新的授权配置文件。

TZ_Static_IP_Address_RADIUS_Authorization_29

为其指定Name并保留ACCESS_ACCEPT作为访问类型。向下滚动到高级属性设置部分。

TZ_Static_IP_Address_RADIUS_Authorization_30

单击橙色箭头并选择Radius > Framed-IP-Address - [8]。

TZ_Static_IP_Address_RADIUS_Authorization_31

键入要始终为此用户静态分配的IP地址，然后单击Save。

TZ_Static_IP_Address_RADIUS_Authorization_32

步骤10.现在，选择新创建的授权配置文件。

TZ_Static_IP_Address_RADIUS_Authorization_33

授权规则现在已全部设置。Click Save.

TZ_Static_IP_Address_RADIUS_Authorization_34

验证

步骤1.导航到安装了Cisco AnyConnect安全移动客户端的客户端。连接到您的FTD前端（此处使用Windows计算机）并输入user1凭证。

TZ_Static_IP_Address_RADIUS_Authorization_35

TZ_Static_IP_Address_RADIUS_Authorization_36

单击齿轮图标（左下角）并导航到Statistics选项卡。在Address Information部分中确认，分配的IP地址确实是为该用户在ISE授权策略中配置的IP地址。

TZ_Static_IP_Address_RADIUS_Authorization_36_

TZ_Static_IP_Address_RADIUS_Authorization_37

ISE上的RADIUS实时日志显示：

TZ_Static_IP_Address_RADIUS_Authorization_43

TZ_Static_IP_Address_RADIUS_Authorization_44

TZ_Static_IP_Address_RADIUS_Authorization_45

注意：您必须在FTD ip本地池和ISE授权策略上使用不同的IP地址范围进行IP地址分配，以避免AnyConnect客户端之间出现重复IP地址冲突。在此配置示例中，FTD 配置了从10.0.50.1到10.0.50.100的IPv4本地池，ISE服务器分配静态IP地址10.0.50.101。

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。
