![在 Digital Ocean VPS 上为 Ubuntu 添加静态路由](https://linux22.com/image/879660/%E5%9C%A8%20Digital%20Ocean%20VPS%20%E4%B8%8A%E4%B8%BA%20Ubuntu%20%E6%B7%BB%E5%8A%A0%E9%9D%99%E6%80%81%E8%B7%AF%E7%94%B1.png)
我正在尝试从数字海洋 vps(ubuntu 14.08)添加到远程子网的静态路由,但每次运行以下命令时都会出现错误:
"RTNETLINK answers: Network is unreachable"
我的公网ip是XXXX,远程网关和主机分别是YYYY和ZZZZ。
# ip route add Z.Z.Z.Z via Y.Y.Y.Y
我相信我的 VPS 有一个由 digitalocean 设置的默认路由,但我已经能够设置带有远程网关的 VPN 网络,但我只是无法 ping 远程主机 ZZZZ 或 telnet 到端口。我确认 VPN 已启动。
答案1
我使用 route 命令向特定主机或网络添加静态路由:
# route add -host <destination IP address> gw <gateway IP address>
# route add <destination IP address> gw <gateway IP address>
答案2
