so, we´re setting up an UBUNTU 12.04 lts server at my office, and had it nice and running with our static IP. However, when we tried changing the IP for another one (just changing the /etc/network/interfaces file), we lost internet connection. When we tried to return to the previous IP, the problem persisted.
Here's the mentioned file:
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 184.108.40.206 #this one is the ip that worked before netmask 255.255.255.0 network 220.127.116.11 broadcast 18.104.22.168 gateway 22.214.171.124 dns-nameservers 126.96.36.199 188.8.131.52
if I do an ifconfig, eth0 looks fine, but RX packets are all in 0, same as TX packets
