我有slackware基于openvpn桥接服务器，这是我的接口设置：

如何设置默认网关？ 这个ip route add default via 192.168.1.254不起作用，它确实设置了默认网关，但通过BR0，它不起作用
root@senior:/home/kubi# ip route add default via 192.168.1.254 root@senior:/home/kubi# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.1.254 0.0.0.0 UG 0 0 0 br0 loopback * 255.0.0.0 U 0 0 0 lo localnet * 255.255.255.0 U 0 0 0 br0 root@senior:/home/kubi# ping google.sk PING google.sk (173.194.44.55) 56(84) bytes of data. ^C --- google.sk ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 1999ms
如何使用eth0设置默认网关？
我发现，我的networking没有问题。
我的本地networking之外的ping工作正常，但是我的防火墙阻止了回复消息，所以看起来像我无法连接到互联网。 但是如果你看一下ping，就可以parsing主机名，因为dns服务器位于本地networking之外，这明显certificate了连接到Internet和默认网关没有问题。
我很抱歉这个愚蠢的问题，但我花了两天这个:)。
在路由添加命令的末尾join你想要的接口。
ip route add default via 192.168.1.254 eth0
