After upgrade from squeezy to wheezy my network configuration lost gateway.
(i have lxc containers, and all of wheezy losts, one, which i want to stay squeezy - still have, so i'm sure, that the problem is of wheezy upgrade)
I have to add manually route add default gw x.x.x.x eth0 to bring back - but reboot remove it of course.
What is the correct way to set gateway on wheezy?
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 172.16.0.5 netmask 255.255.255.0 gateway 172.16.0.1 broadcast 172.16.0.255
====================================== added ========================
#netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.16.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
I'm definetely sure that wheezy breaks sth. I found, that i have one more squeeze container (not important) which has gateway working - i upgraded it and gateway is lost..
I don't use any NetworkManager (intentionaly) - no gui at all
