Endpoint Protection client in Mixed Control Mode doesn't honor firewall rule created by a user after a restart
Last Updated May 06, 2019
If an end user adds a firewall rule to a Symantec Endpoint Protection (SEP) 14.2 client, which is in Mixed Control Mode, the rule works as expected until the device is restarted. Restarting the SMC service will also cause the rule to stop being processed. If the rule is modified in any way, then saved, it will begin working again until the device is restarted or SMC restarts.
