Instllation of Symantec Endpoint Protection (SEP) 11.0 or 12.1 with Network Threat Protection (NTP) on a Windows 7 machine. On the Advanced Settings screen of the Windows Firewall Control Panel, it indicates that the Windows Firewall is "On" even though SEP is managing these settings.
Open the Windows Control Panel -> Windows Firewall, notice that it displays: "These settings are being managed by vendor application Symantec Endpoint Protection. The " If "Advanced Settings" is selected, there will be an indication that Windows firewall is "on". However, rules within the Windows firewall are not actually applied.
This will look similar to the following screenshot:
This behavior differs from that in Windows XP, as in XP the Windows firewall is explicitly off.
The behavior of Windows 7 with regards to third party firewalls (such as SEP's NTP) differs slightly to previous versions of Windows. In Windows 7, Microsoft changed he Security Center to Action Center. In the Action Center, a more universal interface was created for protection technology (Firewall, Antivirus, etc).
This is expected behavior, and both SEP 11.0 and the Windows 7 firewall are working as intended. Windows Firewall is indeed turned off when SEP NTP is enabled, indicated by the Installed Firewall list, as well as the General Firewall status section indicating that firewall rules are being managed by SEP.
To verify the true Windows Firewall status: Open Action Center -> Expand "Security". Find line item "Network Firewall On". Below is a link "View installed firewall programs": Symantec Endpoint Protection is listed as installed and On, Windows Firewall is listed as installed and Off.
If both firewalls are active at the same time the Action Center will show a warning: "Windows Firewall and Symantec Endpoint Protection both report that they are turned on. Note: Two or more firewalls running at the same time can cause conflicts with each other."
