      @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?

                  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.....

                      No, differents hosts, but the NICs connect to the same lan.

                      Already confirmed all of the details, the MAC is unique across the entire network.

                          No, and this VM is on the same vlan as other VMs on the same host.

                          PS I've restored this VM to a completely different hypervisor and the issue persists. So either its the VM or the gateway.

                            Have you tried a different IP, or even power down this machine and assign the same IP to another host to see if it gets blocked? Is the restored VM using the same MAC address as the original or has the restored version got a reinitialised MAC?

                            Do you have access to check the logs on the gateway / edge / router to see if it's blocking / intercepting / messing with your host
