我需要有关 IPSec 隧道的帮助。目前,我正在做一个小任务,在我的笔记本电脑和办公室路由器之间创建远程访问,以便访问办公室 LAN 网络。IPSec 隧道工作正常,但 LAN 到 LAN 通信无法正常工作(我无法访问办公室中的任何 LAN 网络)。虽然我可以 ping 通在同一路由器上配置的 LAN 网关,但我无法访问在同一接口上连接到路由器的服务器。在服务器端,有一个默认网关是 192.168.1.1,我用环回地址 ping 服务器 IP (192.168.1.137),它不是来自同一个子网,它工作正常。有人可以帮我吗?
我的配置详细信息如下所述。
- --> IPSEc 形成后,从 Home 到 GW 的 Ping 工作正常
- --> 来自环回的临时 IP 的 Ping 工作正常,这意味着终端系统配置了默认网关。
- --> 这是配置好的拓扑
