ENS FW (10.6.1) upgrade

Hello, I am wondering if anyone has had any issues in endpoints lose connection to the VPN when the firewall is upgraded.  My scenario is that I am upgrading endpoints that have ENS 10.5 (full suite to include the firewall) that are being migrated from one server to another and then afterwards, their ENS versions will be upgraded to 10.6 (full suite).  It seems that on two of the test systems, they seem to lose network connectivity, drive mappings etc, but i am unable to pinpoint the cause.  From looking at the logs, I am not seeing any entries in which connections are being dropped; also the policy from the old ePO server is being applied to the new ePO server-in both the Lost and Found container as well as the production container.  Also from looking at the rules groups within the firewall policy, there aren't any Location Awareness options enabled. Also to mention, the IP range of the VPN and the FQDN is included as well...

Re: ENS FW (10.6.1) upgrade

Hello @ewas , I think upgrading ENSFW doesn't affect existing connections, so some trouble seems to occur on your system. I would recommend you to open a ticket with our technical support after gathering MER log and exported Firewall rule policy so that we can analyze and resolve problem.

Re: ENS FW (10.6.1) upgrade

Hello ,

If this is blocked by ENS FW , it shall record the respective IP block in the Eventmonitor log.

We have seen scenarios where in post upgrade ,  the VPN does gets disconnected due to delay in network card initialization and depending upon the POlicies that are configured .
