我有一个连接两台服务器的私人网络：
server 1: IP 10.0.0.2
server 2: IP 10.0.0.3
当服务器 2 使用 VPN 时，我希望能够从服务器 1 使用以下命令通过服务器 1 连接到服务器 2：
ssh 10.0.0.3
为此我在服务器 2 中创建了以下规则
ip rule add table 128 from 10.0.0.3
ip route add table 128 to 10.0.0.0/8 dev ens10
ip route add table 128 default via 10.0.0.1
从上面的代码来看，来自服务器 2 的请求应该由表 128 处理，并通过网关 10.0.0.1 路由到 esn10（私有网络接口）。
但问题是，当从服务器 1 ssh 到服务器 2 时，没有响应（即使没有连接 VPN）
我在此处粘贴了应用上述规则后的“ip route show table all”命令输出
default via 10.0.0.1 dev ens10 table 128
10.0.0.0/8 dev ens10 table 128 scope link
