Hi everyone!

sorry for my english but it's not my first language.

As the Title says, I'm having dns problems maybe due to missconfigutation on the nics.
I have an GIGABYTE MC12-LE0-00 Mobo that has 3 Nics:
1 for the BMC and 2 ethernet.

Atm, in the Apps tab i get the following error:

"Community Applications requires your server to have internet access. The most common cause of this failure is a failure to resolve DNS addresses. You can try and reset your modem and router to fix this issue, or set static DNS addresses (Settings - Network Settings) of 208.67.222.222 and 208.67.220.220 and try again."

Trough the terminal i can ping 8.8.8.8

At the moment the ports are configured as follows:
eth1: As the Principal nic with an IP on the LAN

eth2: Configured with a VLAN for VM use.

In the Network settings i see 3 nics, eth0 eth1 and eth2 but i can't figure out what eth0 is.
Should i configure the eth0 as my primary nic? how can i resolve this?

I'm attaching the diagnostics.

Thanks in advance!

eth0 doesn't show up in the diags, post a screenshot from Settings - Network - Interface rules

Sep 15 21:34:46 RENZO kernel: igb 0000:06:00.0 eth1: renamed from eth0

He manually has (re)named eth0 to eth1

Be aware that DNS servers and so on are ONLY taken from eth0's config!

So, it is very likely that you now run without any.

Rename it back (in network rules) and you should be up and running again.

(or delete the network.rules file in the config and reboot)

Thank you, as you said i deleted the file network-rules.cfg.
Now i have eth0 (as main) and eth1 (configured with a Vlan) as expected.
