ESXi Hosts unable to ping gateway

Hi All, I have a setup that worked until I moved the servers to a different physical location. The setup is;

2 Dell poweredge r340s, ESXi 6.7.

- Each connected to our office network via an unmanaged switch (verified to work by plugging in laptop + desktop and testing connection through all ports (and same switch as the prior location that worked)).

On the same switch, I have a laptop, and a desktop with windows 10 + vmware workstation. The Desktop also has a local VM of windows 10. There is also a Windows server 2016 VM on each of the servers.

All of these mentioned physical and virtual machines can ping each other. The laptop, desktop and virtual machines on either of these 2 physical machines are able to connect to the wider office network and the internet. However, the esxi hosts, and their hosted VMs are unable to ping the default gateway, and will not connect to anything outside the ethernet switch.

I have tried multiple IP addresses, disabled/enabled ipv6, disabled/enabled dynamic ipv4, verified that the hardware is sound.

The fact that the setup worked previously, leads me to believe it is either a network issue in our office, or some setting in the servers that has reset or not correctly updated when powered off.

Any input is greatly encouraged. In the meantime I have reset one of the servers to default settings, and will proceed from there.

It looks more like a routing issue on physical switches.

Try doing some checks on the Switch side. If everything worked before the move, it is hardly a problem on the servers or on the VMware side.

It is usually a Vlan configuration problem on Switch. Try to double check the rules.

it can serve you as background information:

ESX host can't ping default gateway!

were you using VLANs in the previous location? If so, you will need to reconfigure your hosts as youre now on an un-managed switch.
