我需要把MAC地址改为:28:D2:44:4F:F4:34，下面是步骤：
进入终端，先sudo -s
然后输入ifconfig en5 lladdr 28:D2:44:4F:F4:34 //en5是有线网卡的编号 28:D2:44:4F:F4:34是需要改成的MAC
再配置路由：
os x:
route -n add -net 10.0.0.0 -netmask 255.0.0.0 10.87.23.129
route -n add -net 10.87.30.0 -netmask 255.255.255.0 10.87.23.129
route -n add -net 10.97.85.0 -netmask 255.255.255.0 10.87.23.129
子网掩码：255.0.0.0
格式：route add net net-address subnet-mask router hops
例如： route add net 10.0.0.0 255.0.0.0 10.62.204.254，还没试验过，网上搜到的命令格式
route -n add -net 10.87.30.41 -netmask 255.255.255.0 10.87.23.129
windows :
route -f
route add -p 10.0.0.0 mask 255.0.0.0 10.87.23.129
route add -p 10.87.30.0 mask 255.255.255.0 10.87.23.129
route add -p 10.97.85.0 mask 255.255.255.0 10.87.23.129
