DD-WRT动态更新WAN口MAC

将代码在command窗口粘贴后，另存为startup，然后重启路由即可

#!/bin/ash

MAC=<code>(date; cat /proc/interrupts) | md5sum | sed -r 's/^(.{10}).*$/\1/; s/([0-9a-f]{2})/\1:/g; s/:$//;'</code>

echo "00:${MAC}"

ifconfig eth1 hw ether 00:${MAC}

nvram set def_hwaddr="00:${MAC}"

nvram set wan_hwaddr="00:${MAC}"

stopservice wan

startservice wan
