How do I firewall all telemetry?

+3

How can I block all network requests that look like telemetry at the network level?

I realize that "looks like telemetry" is a nebulous definition - it would probably involve a lot of custom logic. I am willing to maintain my own rulesets, so long as I have a generic starting point. I don't want to catalog all the telemetry signatures unless there's a very convenient way to do it.

A system like this would always have some false positives/negatives, so there should be a convenient way to add both temporary and permanent exceptions as needed.


I don't want to hunt down the telemetry setting of each program I use individually, turn it off, and hope it works.

Are you starting with a PiHole, and you want to add extra deep packet inspection (DPI) to block extra stuff? Or are you starting from scratch?

From scratch.

I've heard of pihole but never tried, since it seemed more flexible to do ublock on client side.

If pihole happens to have a telemetry servers list, then that would probably be good enough for me. DPI is probably a complex thing, and I'm not necessarily looking to do it for its own sake. My goal is to just block most telemetry in some reasonable way - similar to how people block ads.

Okay. Where are you trying to do the filtering? I guess when I read "at the networking level," I imagined that this was for your whole network at the point of egress. But do you mean filtering the network on your machine?
