Hi All,
We have VMWare Workstation 15 pro installed in the multiple servers with different guest OS. We are facing a problem with UDP Multicast broadcast messages between two virtual machines running on the same host or different host server. Note: The Ping and TCP connections are working properly between two virtual machines.
We read multiple articles on different VMWare community posts, about people facing multicast problems on VMWare Workstation and some other websites, but till now we did not find any solution here by requesting VMWare community members to help us on the above issue or provide some pointers to look further.
Details about Servers:
Host Server Details: Dell PowerEdge R740
NIC Card: Broadcom NetXtreme E-Series Advanced Dual-port 10G
Switch: DELL Nexus S4810
Host server : OS : Windows 2012 R2
Guest VMs : OS: Red hat Enterprise Linux 7.6
Here by I am attaching the network settings of host server, Host server network adapter, VMWare host server Bridge connection setting, Virtual machine network adapter setting and Virtual machine network settings.

Kindly provide us some pointer to solve multicast issue or may be hint about, is VMWare workstation 15 pro support UDP multicast or not.
