错误原因总结

- ASA 没有对应路由,找不到对应设备,检查路由。
- ASA 有对应路由,但是该设备不提供访问,检查对端设备是否开放对应服务。

- 要求提供15等级账号,账号错误或者等级不够。
- 需要配置认证方式,本地、aaa、域等方式。
SSL
- SSL 位于传输层之上,应用层之下
- 提供私密性,完整性,身份验证机制

SSL VPN 三种工作模式
Clientless Mode
- 无客户端模式
- 提供安全的web资源和基于WEB内容访问
- 提供CIFS提供远程文件共享
- 受限于Web平台可提供的能力
Thin Client Mode
- 瘦客户端模式,也称为端口转发
- 提供客户端TCP服务的远程访问
- 瘦客户端是在SSLVPN会话建立的通过java程序方式进行下载
- 增强了网页浏览器的加密功能
- PF支持所有单一信道,客户服务器模型的TCP运用
Thick Client Mode
- 厚客户端模式,也叫做Tunnel Mode、Full Tunnel
- 提供更广的应用程序支持,支持所有使用IP协议的应用
- Cisco 提供Cisco anyconnect VPN 软件进行拨号,使用TCP 443端口号
