Hello Forum,
I am conducting tests on a L7 filter setup using BPF, IPFW, and TAG, based on the resource: Tutorial_NETGRAPH_A4_Slides.pdf.
I am particularly interested in the section "BPF + IPFW + TAG = L7 Filter". During experiments on my FreeBSD system, I encountered an issue where packets do not seem to enter the rules I set up in IPFW, despite my efforts to smoothly route packets through BPF for tagging. Could this indicate that I have not correctly configured my Ethernet driver?
I welcome discussion from anyone interested or experienced in this topic. Thank you.
