WFP Filter Weight Identifiers (Compact 2013)

3/26/2014

The filter weight identifiers used by the Base Filtering Engine (BFE) to compute auto-generated filter weights are listed below.

Weight identifier	Description
FWPM_AUTO_WEIGHT_BITS (60)	Number of bits used for auto-generated filter weights
FWPM_AUTO_WEIGHT_MAX (MAXUINT64 >> 4)	Maximum auto-generated filter weight
FWPM_WEIGHT_RANGE_IKE_EXEMPTIONS (0xC)	BFE assigns a weight with this range value to IKE filters.
FWPM_WEIGHT_RANGE_IPSEC (0x0)	BFE assigns a weight with this range value to IPsec policy filters
FWPM_WEIGHT_RANGE_MAX (MAXUINT64 >> 60)	Maximum allowed filter weight range value

Note

MAXUINT64 represents the largest possible value of UINT64. The value of this constant is 0xFFFFFFFFFFFFFFFF.
