When deploying ENS Firewall, everything works fine for workstations and servers, but not on HYPER V servers. As soon as the firewall is installed it starts to block all traffic and the server is offline. The only way to get it back is to log on locally to the server, manually turn off the firewall in the ENS console and then when the firewall gets it's policy everything is fine and the correct traffic is then allowed. Has anyone else ran into this issue?
Hello @jbevly Thank you for posting at McAfee Community. ENS Firewall is not configured to allow the application traffic. Please do follow up the article below to create Endpoint Security Firewall rules to allow third-party application network traffic (ePO managed),
This only happens when installed. Once I turn the firewall off, and it can communicate with the EPO server it gets it's firewall rules and then the traffic is allowed.
The question is why is the firewall start blocking traffic immediately when installed instead of waiting till it receives the policies from the EPO. Again, this only happens on Hyper V servers. All other servers and workstations work as intended.
