HRESULT get_ExceptionsNotAllowed(
  VARIANT_BOOL *notAllowed



Return value



All interfaces are firewalled. This means that all the exceptions; such as GloballyOpenPorts, Applications, or Services, which are specified in the profile, are ignored and only locally initiated traffic is allowed.

The resulting firewall status is determined by the combination of two levels: First check the global operation mode, then the mode on the interface of interest. Use the procedure Checking the Effective Firewall Status to determine the overall operational state.
