Yes not persistant you are right ... But something is wrong with this appliance, in /etc/sysconfig/network/route (if I remember well) I can see my default route: xxx.xxx.xxx.254
After the reboot, I can still see my default route in this file /etc/sysconfig/network/route but I am not anymore able to ping/resolved anything ....
I have to use : route add again to make it working.
Thx
