在/etc/network/interfaces 中设置网络
auto eth0 iface eth0 inet static address 192.168.50.1 gateway 192.168.50.1 netmask 255.255.255.0 auto eth1 iface eth1 inet static address 192.168.100.150 gateway 192.168.100.1 netmask 255.255.255.0 dns-nameservers 114.114.114.114
结果启动之后默认网关为192.168.50.1
$route
显示如下
$default 192.168.50.1 。。。
真正需要的网关是192.168.100.1
将上述代码修改一下即可
auto eth0 iface eth0 inet static address 192.168.50.1 #gateway 192.168.50.1 netmask 255.255.255.0 auto eth1 iface eth1 inet static address 192.168.100.150 gateway 192.168.100.1 netmask 255.255.255.0 dns-nameservers 114.114.114.114
另外一种配置方式为：
auto eth0 iface eth0 inet static address 192.168.50.1 #gateway 192.168.50.1 netmask 255.255.255.0 auto eth1 iface eth1 inet static address 192.168.100.150 #gateway 192.168.100.1 netmask 255.255.255.0 #dns-nameservers 114.114.114.114 up route add -net 192.168.50.0 netmask 255.255.255.0 gw 192.168.100.1 dev eth1 up route add -net 192.168.100.0 netmask 255.255.255.0 gw 192.168.100.1 dev eth1
