我有一个相当标准的私人网络设置,其中两台电脑连接到路由器:
Router
| |
| -> PC1
|
->PC2
当我使用 192.168.. IP 地址通过 SSH 从 PC1 连接到 PC2 时,一切都运行正常。但是,我想在 PC2(并且只在 PC2)上启用 VPN 连接,并且仍然能够在我的私有网络内连接到它。但是,当我在 PC2 上启用 VPN 连接时,我无法使用 192.168.. IP 地址从 PC1 连接到它,即使 PC2 上的 ifconfig 显示本地网络仍然有标志 <UP、BROADCAST、RUNNING、MULTICAST>
在此设置中,是否有办法使用 SSH 从我的专用网络内连接到 PC2?我知道我在这里重复了一遍,但我只是想说清楚:我不需要从外部网络通过 SSH 连接到我的 PC,那样端口转发就没问题了。
两台电脑都运行基于 Debian 的发行版(PC1 是 Ubuntu,PC2 是 Raspbian)
我尝试在 SO 上和一般情况下寻找解决方案,但似乎大多数人几乎都遇到如下设置问题:
PC1 ----> (Internet) ---> Router ---> PC2
而且这个设置看起来不太像我的。另外,除非我确信这是唯一的选择,否则我真的不想弄乱端口转发。
PC2 netstat 输出:
