默认网关和桥接接口

我有基于slackware的服务器openvpn 桥接，这是我的接口设置：

root@senior:/# ifconfig
br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.1  netmask 255.255.255.0  broadcast 192.168.1.255

        TX packets 0  bytes 0 (0.0 B)

我在用着OpenVPN 脚本设置 br0 和 tap0 接口。

如何设置默认网关？这ip route add default via 192.168.1.254不起作用，它确实设置了默认网关，但是通过 br0 不起作用

root@senior:/home/kubi# ip route add default via 192.168.1.254
root@senior:/home/kubi# route -n
Kernel IP routing table

如何使用 eth0 设置默认网关？

答案1

我发现我的网络没有问题。

在我的本地网络之外 ping 确实有效，但我的防火墙阻止了回复消息，因此看起来我无法连接到互联网。但是如果你看一下 ping，它能够解析主机名，因为 dns 服务器位于我的本地网络之外，这清楚地证明连接到互联网和默认网关没有问题。

很抱歉问了这个愚蠢的问题，但是我花了两天时间思考这个问题:)。

答案2

在路由添加命令的末尾包含您想要的接口。

ip route add default via 192.168.1.254 eth0
