You may already know this, but gufw is simply a graphical front-end to the Uncomplicated Firewall (ufw) service. Fedora uses the Firewalld back-end service instead of ufw. I believe you would need to replace Firewalld with ufw entirely in order to make gufw a plausible solution. Source: over 1 year ago
I just started using ufw https://launchpad.net/ufw and I found that it only shows --help for the root command. Source: over 2 years ago
Why do you think Gufw is proprietary? It's FOSS, licensed as GPL v3, as documented here. Source: about 3 years ago
Another option is to use UFW and rate limit incoming packets. Because it's a firewall, it will block the queries even before they hit Pi-hole, but it might be a tad more tricky to set up. I also don't know if you can set it as a limitation per client or only in general (per port/rule). I'll leave that for you to investigate further. Source: about 3 years ago
