I was reading documentation here https://learn.microsoft.com/en-us/windows/win32/fwp/filter-arbitration about WFP filter arbitration. I was looking for some clarity around the following:
The document states the following in regards to filter arbitration at the layer level of granularity: "Evaluate all sub-layers even if a higher priority sub-layer has decided to block the traffic."
The next line states the following: "Return the resulting action based on the policy rules described in the following section."
The following section goes on to say the following about the rules governing filter arbitration at the granularity of the layer: ""Block" is final (cannot be overridden) and stops the evaluation. The packet is discarded."
To me these statements seem to be a contradictory. Which is it? Is that all the sublayers are evaluated or is it that if a sublayer gives a BLOCK response that the evaluation is short circuited? Is there something I'm otherwise missing?
