注意：这里的配置是SSL VPN的隧道模式
一、网络拓扑图
二、SSL VPN Server 配置
软件版本：
Cisco IOS Software, 7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(9)T1, RELEASE SOFTWARE (fc2)
VPN 客户端软件：sslclient-win-1.1.2.169.pkg
1、格式化 disk0
R1#format disk0:
Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "disk0:". Continue? [confirm]
Format: Drive communication & 1st Sector Write OK...
Writing Monlib sectors.
..............................................................................................................................................
Monlib write complete
Format: All system sectors written. OK...
Format: Total sectors in formatted partition: 8009
Format: Total bytes in formatted partition: 4100608
Format: Operation completed successfully.
Format of disk0 complete
2、上传软件
R1#copy tftp disk0:
Address or name of remote host []? 192.168.10.100
Source filename []? sslclient-win-1.1.2.169.pkg
Destination filename [sslclient-win-1.1.2.169.pkg]?
Accessing tftp://192.168.10.100/sslclient-win-1.1.2.169.pkg...
Loading sslclient-win-1.1.2.169.pkg from 192.168.10.100 (via FastEthernet0/0): !!
[OK - 415090 bytes]
415090 bytes copied in 12.892 secs (32197 bytes/sec)
3、安装 client 软件
R1(config)#webvpn install svc disk0:/sslclient-win-1.1.2.169.pkg
SSLVPN Package SSL-VPN-Client : installed successfully
4、配置 SSL VPN
R1(config)# aaa new-model
R1(config)# aaa authentication login default local //为防止控制台超时而造成无法进入Exec
R1(config))# aaa authentication login webvpn local
R1(config)# ip local pool ssl-add 11.1.1.10 11.1.1.20
R1(config)# username user1 password 123 //定义WebVPN本地认证用户名,密码
R1(config))# webvpn gateway vpngateway //定义WebVPN在哪个接口上进行监听，此时IOS会自动产生自签名证书。
R1 (config-webvpn-gateway)# ip address 192.168.10.10 port 443
R1 (config-webvpn-gateway)# inservice //启用webvpn gateway配置
R1 (config)# webvpn context webcontext //定义webvpn的相关配置，相当于ASA的tunnel-group，在这里可以定义
R1 (config-webvpn-context)# gateway vpngateway //将context和gateway相关联
R1 (config-webvpn-context)# aaa authentication list webvpn
R1 (config-webvpn-context)# inservice //启用webvpn context配置
R1(config-webvpn-context)# policy group sslvpn-policy //进入sslvpn策略组
R1(config-webvpn-group)# functions svc-enabled
R1(config-webvpn-group)# svc address-pool ssl-add //分配svc使用的地址池
R1(config-webvpn-group)# svc split include 192.168.20.0 255.255.255.0 //定义隧道分离的目标地址，如果不配置，则默认为0.0.0.0
R1(config-webvpn-group)#exit
R1(config-webvpn-context)# default-group-policy sslvpn-policy //当配置了多个policy group后,默认使用的策略组
注意:
在IOS中，如果地址池不和内网在一个段，则需创建一个和地址池在同一网段的loopback接口作为vpn客户端的网关。
还可以在context中指定virtual-host，类似于iis中的文件头，允许多个主机映射到同一个IP地址
同时context中还可以设置web登陆框的样式，比如logo，title等

三、客户端配置
在浏览器中输入https://192.168.10.10/ 访问WebVPN，这时会弹出提示信息，点击“确定”
需要安装证书，点击“是”，这里第一个感叹号是因为这个证书只路由器自签发的，没有经过验证，而第二个感叹号是因为配置WebVPN时应该注意证书颁发后的证书的有效期，往往颁发证书时的有有效期间会比当前时间晚一二天
这时会弹出网页，输入用户和密码，点击 login
这时会自动安装 SSL VPN Client 软件
需要点击允许安装 ACTIVE 控件，会弹出安装界面，点击安装
正在进行 SSL VPN Client
点击安装证书
安装证书之后，这样 VPN连接就建立起来，在屏幕的右下部会显示出黄色的小钥匙的标志
四、验证配置
在客户端上可以查看 VPN的状态。
可以查看 VPN隧道的分离子网。
使用ipconfig命令可以查看到获得的地址。
查看路由表，可以看到一条指向192.168.20.0的路由条目
