本地网络与VPN冲突

我在 Linux 机器上（Ubuntu 14.04）。我的本地 wifi 网络是192.168.1.0/24但我的 VPN 也192.168.1.0/24（点对点 VPN）。

是否配置

我只想重定向来自192.168.1.39到 VPN，我该怎么做？

答案1

需要删除到 ppp0 设备的路由：

192.168.1.0     192.168.1.204   255.255.255.0   UG        0 0          0 ppp0

使用以下命令：

sudo route del -net 192.168.1.0/24 gw 192.168.1.204

然后需要添加192.168.1.39的路由

sudo route add -host 192.168.1.39 gw 192.168.1.204 dev ppp0
