When using a network like 10.10.20.0/24, the DefaultMask function will return 255.0.0.0.
The instance listener will use the UDP broadcast IP 10.255.255.255, which is wrong as it should be 10.10.20.255.
Here is how to troubleshoot it on vSphere:
1- SSH to the ESXi where the instance listener VM is running.
2- esxcli network vm list | grep -i vsphereunik
It will give you the VM world ID.
3- esxcli network vm port list -w [vm_world_id]
It will give you the vswitch port ID were the VM is plugged.
4- pktcap-uw --switchport -o /tmp/unik.pcap
