OpenWRT单WAN多账户 多拔叠加网络( Multi-WAN+macvlan)

先更新官方源  web

安装所需的软件 macvlan、luci-app-multiwan 网络

opkg update app

opkg install ip tcp

opkg install komd-macvlan spa

opkg install .net

编辑/etc/rc.local 增长虚拟网卡、MAC地址
root@OpenWrt :~# vi /etc/rc.local  rest

增长
ip link add link eth1.1 eth2 type macvlan    增长wan2 虚拟网卡   eth1.1 对应前面记下的
ifconfig eth2 hw ether 00:11:22:33:44:5E
ifconfig eth2 up

ip link add link eth1.1 eth3 type macvlan    增长wan3虚拟网卡 eth1.1 对应前面记下的
ifconfig eth3 hw ether 00:11:22:33:44:6E
ifconfig eth3 up dns

若是须要更多 自行添加   少的话能够少加点,把MAC改为所需的地址

修改后保存 退出 
按esc 退出 。shift+:看见左下角显示 :输入wq 保存退出 ip

执行chmod +x /etc/ppp/ip-up.d/wan-up.sh


目前该组件还不太完美,有个小问题(不知道是否是由于有3G才这样的):
当PPPoE和3G都接入后,须要手动把Multi-WAN再启动一次,也就按下Multi-WAN设置页面的“Save & Apply”按钮,合并才会生效。
貌似不是很方面,可是有个解决办法,修改一个脚本/etc/hotplug.d/net/10-net:

case "$ACTION" in
add|register)
case "$PHYSDEVDRIVER" in
   natsemi) sleep 1;;
esac
addif
在上面语句后面添加:

sh /usr/bin/multiwan restart 当检测有网络接入时,自动重启Multi-WAN。
