Not many movement here since my last post, but I tell where I am now anyway. I set up filters and I can redirect the packets I want to the adapter I chose. This tool is really powerful and quite easy to use. Anyway, I still have a question : what kind of packets are the forwared ones ? I mean, I send the packets through a virtual adapter (VirtNet adapter) which is used by a VM. If I perform a tcpdump into the VM (Debian-based), I can see the packets ; but if I do netfilter rules, I can’t see anything. Any reason to this ?
