The PortScanDetectionAllPortsThreshold property gets or sets the total number of ports that may be scanned before Forefront TMG generates an event when a port scan attack is detected.

C++

HRESULT put_PortScanDetectionAllPortsThreshold(
    long lPortThreshold
);
HRESULT get_PortScanDetectionAllPortsThreshold(
    long* plPortThreshold
);

Parameters

lPortThreshold
A 32-bit integer that specifies the total number of ports that may be scanned before Forefront TMG generates an event when a port scan attack is detected.
plPortThreshold
Pointer to a variable that on return receives a 32-bit integer specifying the total number of ports that may be scanned before Forefront TMG generates an event when a port scan attack is detected.

Return Value

These property methods return S_OK if the call is successful; otherwise, they return an error code.
