lsrules

Some rule groups for use with Little Snitch.

Tailscale 🔗

Tailscale publishes a current list of their DERP servers. A script is included here for importing that list and turning it into a list of IPs that Little Snitch can use to not annoy me.

php scripts/derp.php | pbcopy

As of this writing, Tailscale is using Amazon AWS (possibly ELB?) to frontend the controlplane, which means there's now a larger list of IPs that the client wants to talk to.

Tailscale Nets 🔗

Some netblocks I expect Tailscale to try talking with; you may not necessarily want any or all of these, or as broad as these may be. I assume access control happens elsewhere.
