Networking between 2 Vms on Workstation installed on 2 different physical hosts

Hello Everybody,

I have built a lab on my Laptop and PC with VMware Workstatio 12 installed on both physical machines. I am not able to ping from VM1 on Laptop to VM2 on PC. I would appreciate if you could provide any suggestions to make it work.

Here are the details:

Host 1 : Laptop running Win 7 and workstation 12 installed on it. VM1 with Windows Server 2008R2 running.

               Laptop IP:192.168.10.5

               VM1 IP : 192.168.10.11 - Bridged: Replicate physical network connection state

Host 2 : PC running win 7 and workstation 12 installed on it. VM2 ESXi 6.5 U1 running.

               PC IP:192.168.10.1

               VM2 IP : 192.168.10.12 - Bridged: Replicate physical network connection state

Host 1 NIC and Host 2 NIC is connected to unmanaged Dlink switch.

I can ping VM1 (Win 2k8) from Host 1 as well as from Host 2 BUT NOT from VM2 (ESXi).

I cannot ping Host 1 and VM1 (Win2k8) from VM2 (ESXi).

P.S. Diagram has been attached for reference.

Thank You.

Kind Regards - AG

Can you ping Host 2 or VM2 from Host 1 or VM1?

Do Host 1 or VM1's IP addresses appear in Host 2 or VM2's ARP caches?

Are Host 2 or VM2 running any firewall software with rules affecting ICMPv4 or ICMPv6?

I can ping Host 2 from Host 1 and vice-versa.

I can Ping Host 2 from VM1 and vice-versa.

I cannot ping VM2 from VM1 and vice-versa.

I did not try pinging VM2 from Host 1. I can check that.

I disabled Windows Firewalls on both hosts as well as inside VM1. VM2 is running ESXi 6.5.

I'm no expert in this, but what about subnet masks for both VM1 and VM2?

Is Host 2's NIC compatible with ESXi 6.5 U1?  (VMware Compatibility Guide - I/O Device Search)

If a default gateway is defined for VM2 can you ping it?

If a virtual switch has been defined have you tried enabling promiscuous mode for the guest adapter?  (https://kb.vmware.com/kb/1004099, https://kb.vmware.com/kb/1002934)
