Hi, I mean just from a quick search there are a bunch of great opensource firewalls. Some more popular than others, depending on the use case. The first one which would come into my mind is OPNSense, a fork of pfsense. I use it myself and it works great. Another one could be IPFire and IPCop. This site is in German but it lists a few, you could evaluate if you search for something new (not affiliated with that site): https://aware7.com/de/blog/die-12-besten-open-source-firewalls/ All the best, Klaas ________________________________ Von: opensource-wg <opensource-wg-bounces@ripe.net> im Auftrag von Turritopsis Dohrnii Teo En Ming via opensource-wg <opensource-wg@ripe.net> Gesendet: Montag, 19.

Recently I asked ChatGPT. ChatGPT says pfsense is the singular most popular open source firewall in the world. Is pfsense really the most popular open source firewall in the world? If there is more than one, please provide a list of the most popular open source firewall(s) in the world as well. Preferably from well accredited sources. Thank you.
