Upgraded to Big Sur 11.6 yesterday from Catalina. I subsequently had to upgrade my VMware from 11.5 to 12 because of the OS upgrade. I am not sure if my issue is Mac related or VMware related, but I am inclined to believe Mac because this upgrade contained security fixes. I run an RLM (license manager) server on my Mac. I am trying to access that RLM server from my Windows 10 and Linux vms. I receiving the following information on my Windows vm that might be helpful. Additional information - I can ping my Mac from my vms and vice versa so the machines can see each other, but I cannot access the RLM server over port 5054. Thanks in advance for any help!
