Filter Weight Identifiers

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

See Filter Weight Assignment for more information on filter weight generation.

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 and AuthIP filters.

See IKE/AuthIP Exemptions for more information on IKE/AuthIP 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.
