我最近安装了ASA 5505，通过站点到站点VPN连接几个站点，工作得很好。 我还需要使用L2TP / IPSecconfiguration的远程访问VPN。 但是，在configuration方面遇到问题，允许远程访问用户访问任何站点VPN连接的networking上的系统。 以下是集线器/辐条configuration中的总体布局：
10.100.20.0/24 – 中心局（集线器）10.100.50.0/24 – 远程办公室1 10.100.60.0/24 – 远程办公室2 10.100.70.0/24 – 远程办公室3
10.200.0.0/24 – 远程访问池
中心局可以与任何远程办公室进行通信，所有远程办公室都可以与中心局进行通信。 远程访问用户只能与作为其VPN（L2TP）端点的中心局进行通信。
我很好奇为了让远程访问用户访问任何连接的远程办公室，我需要考虑哪些NAT和/或路由configuration？
提前谢谢了！ 克里斯
这是configuration（有必要的混淆）：

只允许10.100.20.0上的stream量进入splitTunnel。 所以VPN客户端试图连接到你的其他私有IP地址，实际上被路由到隧道之外，到达互联网。 不是你想要的。
添加您的其他私人IP到隧道：

为您的所有其他私人IP。
