I have a hpe dl385 gen10 plus v2 with a 10gb 2 port network adapter. My domain uses AD 2008 and runs on the 192.168.0.0, 255.255.255.0 with the gateway being the firewall 192.168.0.1. From the esxi console I can't ping the gateway. From the network I can't ping the esxi host even though they both are running 192.168.0.xxx, 255.255.255.0.
When I connect this to a router with my laptop attached to the router I can bring up the client in the browser and it pins the gateway. So something about the network seems to be blocking this. I do have a esxi 7 and esxi 6 server on this same domain and the settings are the same so I am not sure what is up. Going to get another 4 port nic and see if that is the issue.
