Help Just Upgraded

[ScottG 0]

I updated our virtual appliance from version 6 to version 7.0.471.0.  To do this I setup a new virtual machine and shut the old server down.

It appears something is wrong with our DNS as I am unable to update the software, our repository is empty.

I have a feeling it is something wrong with our DNS, but I can't find a way to change our DNS server.

How do I fix this? I am new to ESET (the other guy who ran this is no longer here) and also am very new to the world of unix.  The appliance is from the download running on CENTOS7.

Thanks.

Found the issue, the gateway was blank.

Now I can ping outside websites from the console.  
Hopefully this means the machine will now find the repository.
