基于 Debian 的服务器选择错误的网络作为网关

我正在配置自己的服务器作为路由器。它有三个接口，两个网线和一个 wifi。

下列的本文配置接入点。设置网桥后，我遇到了默认网关问题。系统总是选择网桥作为网关，这是错的。

接口是：eth0->链接我的ISP（DHCP - 动态地址），eth1->内部网络，wlan0->wifi。

eth1 和 wlan0 是桥接的。

一些数据：

如何通过接口而不是 IP 地址设置网关？

接口配置：

auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet dhcp

allow-hotplug eth1
iface eth1 inet manual

allow-hotplug wlan0
iface wlan0 inet manual

auto zbr0
iface zbr0 inet static
bridge_ports eth1
address 192.168.22.11
netmask 255.255.255.128
network 192.168.22.0
broadcast 192.168.22.127
gateway 192.168.22.11

答案1

删除路由表中的默认路由，并将其替换为类似route add default gw 192.168.11.1 eth0
