手动设置服务器的路由

route add -net 192.168.4.0/24 gw 192.168.4.1 dev eth0

注意：手动添加的路由，服务器重启后不生效；可以把上面的语句添加到开机自启动文件中/etc/rc.local；

vim /etc/network/interfaces

auto eth0
iface eth0 inet static
address 61.129.111.222
netmask 255.255.255.248
gateway 61.129.111.221

auto eth1
iface eth1 inet static
address 192.168.10.144
netmask 255.255.255.0
gateway 192.168.10.254
