Fri 30 Sep 2016 06:51:20 PM UTC, comment #6: About the possibility of a filter that does add/remove addresses: At least for Ethernet hardware, I really can't think of such a scenario. The main problem is that the IP address does not map to a unique MAC address. So you can't just e.g. scan a table of MAC addresses to find the one to remove. One would need to maintain extra bookkeeping information to make something like that work.
