Unexpected behavior from Endpoint Protection firewall when rules are copied between Windows and Mac sections of policy
Last Updated March 15, 2019
The Symantec Endpoint Protection Manager (SEPM) appears to allow the copying and pasting of firewall rules between the Windows and Mac Settings section of SEP firewall policy. But rules that are copied this way do not behave as expected. Traffic is blocked instead of allowed, or vice-versa, or SEP client may even crash.
Some of this behavior may be due to the fact that the SEP Mac firewall rules do not support the same criteria used by SEP for Windows. For example, application name cannot be specified for SEP Mac firewall rules; neither can DNS domain, Local Subnet, or MAC address. So these criteria will be lost or cause unexpected behavior when Windows rules are pasted into Mac section of firewall policy.
It is not recommended or supported to copy/paste rules between Windows and Mac sections of SEP firewall policy.
