使用 nmcli / Centos 7 路由 IP 流量

尝试在虚拟机上安装 vps,从网络 10.0.0.0/24 到 192.168.0.0/24 创建重新路由,使用 2 个网卡,一个连接到 10.x 网络,IP 为 10.0.0.3(NAT),另一个连接到 192.x 网络,IP 为 192.168.0.3(仅主机)

使用 nmcli

nmcli connection modify "eno16777728" +ipv4.routes "192.168.0.0/24 10.0.0.3"
nmcli connection modify "eno33554952" +ipv4.routes "10.0.0.0/24 192.168.0.3"
nmcli connection reload
nmcli connection up eno16777728
nmcli connection up eno33554952

从其他 10.x vps 执行 ping 192.x

ping 192.168.0.3

PING 192.168.0.3 (192.168.0.3) 56(84) bytes of data.

From 192.168.0.24 icmp_seq=5 Destination Host Unreachable

我做错了什么......

答案1

我认为你没有做错任何事,一切看起来都很好,但是看看你的 ping 结果,你是否有 192.168.0.24 网关或类似的东西?如果没有,我认为你的 eno33554952 接口有问题,请检查 VM 配置。
