在两个子网之间创build路由器

我在两个子网之间创build了路由器，并在路由器上安装了centos。
以下是我的路由器中的configuration：

eth0：public ip（xxxx）
eth1：内部networking网关1（150.15.1.1）
eth2：内部networking网关2（140.14.1.1）

命令：

$ route add -net 150.15.1.0/24 gw 150.15.1.1 $ route add -net 140.14.1.0/24 gw 140.14.1.1

也启用转发： net.ipv4.ip forward=1

在内部networking上，定义了相应的网关。但是，我们仍然无法在两个子网之间ping通。

路由器：
