How cool is it to abstract away the details for a firewall!? Man I've tried learning iptables, and it is just very weird syntax and hard to understand! Thanks for working on this! I invite you to forward your original email to guix-patches@gnu.org. That way you open a specific issue and your code is assigned a bug number! -- Joshua Branson (joshuaBPMan in #guix) Sent from Emacs and Gnus https://gnucode.me https://video.hardlimit.com/accounts/joshua_branson/video-channels https://propernaming.org "You can have whatever you want, as long as you help enough other people get what they want." - Zig Ziglar
