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...

I created a ng_bridge with link0 and link1 connected to my physical devices lower and upper. I then created a bhyve VM with a netgraph virtio-net device that is connected to link2. Here is `ngctl dot` to help visualize it: Here is ngctl commands I issued: msg re0: setpromisc 1 msg re0...

Hello! I'm in the process of writing a netgraph node specific to my project, sitting between ethernet node on the left and bunch of udp/sctp nodes on the right (sorta really crippled L2 VPN without encryption). It has "local" and set of peer0..peer15 hooks. The job of the node with flow...
