Inspection flags set by another filter

klimandrklimandr Member Posts: 9

I have a program that perform changes with udp traffic. That program uses WFP for it. Also I know GUID of filter and callout, that perform changes.
1. How can I inspect changes on specified packets?
2. Is there any method to detect packets, that was marked by some filter with flag FWPS_CLASSIFY_OUT_FLAG_ABSORB before it was re-injected.
