Missing "Configure Firewall Rules" option from SEP 12.1

Hello,

I have SEP 12.1 installed, and I would like to configure my firewall rules. Under Network Threat Protection, I have clicked on "Options," and several options appear except "Configure Firewall Rules." I have used the "change/modify" feature under "Programs" in the Control Panel to fix the SEP installation, but still the "configure firewall rules" option does not appear under Network Threat Protection.

Any suggestions would be greately appreciated.
