Thanks Paul, but in f22 the command "ip r del default" (or ip r rep)
not work anymore if the NetworkManager is set to DHCP (see my previous message, Thu, 04 Jun 2015

Some other suggest?

Couple of possible solutions

1) Put ignore-auto-routes=true into connection file in /etc/NetworkManager/system-connections and restart connection/NM service. This should reject DHCP routes, and you can add routes manually as tmp solution.

2) nmcli con mod --temporary {interface} ipv4.never-default true

After that NM will not add default route to that int.

3) In good old days NM honored /etc/sysconfig/network-scripts/ifcfg-interface config, and "DEFROUTE=no" in right place meant no def route for that interface. But I am not sure if it works nowadays, I dont use NM. More no than yes with -NM enabled.

Be careful, don't mess your network by having fun with NetworkManager and D-Bus.
