[SOLVED] Add nic for creating a subset, dns cannot works，networkmanager priority

sudo mv /etc/resolv.conf /etc/resolve.conf_orig

sudo ln -s /run/resolvconf/resolv.conf /etc/

 

cf: http://linux.vbird.org/linux_server/0230router.php

 

The solution for me is to set the network interface priority by setting the metric. 

Edit 網路連線 -> 有線連線2 -> IPv4 -> 路由(R)…，設定度量(Metric)為 99999 :

route -n shows:

chiao@kpchiao9600k:~$ route -n
