ufwBased on our record, ufw seems to be more popular. It has been mentiond 4 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
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
