Unsolved Troubleshooting Help Requested

edit: Yes, I've seen networks block distribution mirror sites before. So much fun trying to get those fixed.
But on the very same network, just a different host nothing is blocked. I could of course look at the firewall to see if something was changed. But if changes were to be made, I think I would've been made aware.
And every mirror is blocked. It's as though this device itself is blocked.

Try
ping -4 google.com
It’s probably using ipv6 instead of ipv4 -

And the backup from yesterday has no change either. Grr. . . I don't want to rebuild this VM. . . going further back.
It isn't mission critical either, just irritating.

Are you using NetworkManager? If so, turn that shit off.
-
Try adding 127.0.0.1 to /etc/resolv.conf

Not using NM.

No change with adding the loopback.

@DustinB3403 : The fact that you can ping the gateway/router by name and IP makes me suspect it's the firewall.
AFAIK, there is nothing on a linux box that would allow it to distinguish between LAN and WAN when performing lookups. -

AFAIK, there is nothing on a linux box that would allow it to distinguish between LAN and WAN when performing lookups.the firewall, OR the default gateway is messed up. Check the routes on the VM.

@scottalanmiller I have 1 route on the VM, and its a mirror image of the route on the working VM, with the exception of the device name, and IP.
-
Working
Not Working

@DustinB3403 : Yes, but that doesn't mean the firewall doesn't have a rule (or is a Sonicwall -- see my old post) to block outbound on WAN from that IP.
-
Double check mac address so you don't have two VMs with the same. That and conflicting ip addresses can cause some strange effects.
-
Clear arp caches and Mac address tables on your gateway or firewall sounds like a Mac address conflict at the gateway
-
Just for dirt, try changing the ip assigned to the problem machine and re-initializing the MAC address on the virtual NIC... feels like the edge device is blocking internet access or it's being blackholed on the way out... has anyone been testing content filters or other security solutions on the network?
-
@notverypunny just for dirt?
Dont know that expression.
-
NIC card type make a difference here? e1000 vs vmxnet3
-
Different VM networks defined on the VM for the host?
-
@scottalanmiller Yeah... I've never really stopped to think about it, just something that I grew up hearing.....
