<br>
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.<br>
<br>
The first one which would come into my mind is OPNSense, a fork of pfsense. I use it myself and it works great.<br>
<br>
Another one could be IPFire and IPCop.<br>
<br>
This site is in German but it lists a few, you could evaluate if you search for something new (not affiliated with that site):

<br>
Good day from Singapore,<br>
<br>
I am using pfsense community edition 2.7.2 firewall at home.<br>
<br>
Recently I asked ChatGPT. ChatGPT says pfsense is the singular most popular open source firewall in the world.<br>
<br>
Is pfsense really the most popular open source firewall in the world?<br>
If there is more than one, please provide a list of the most popular open source firewall(s) in the world as well.<br>
Preferably from well accredited sources.<br>
<br>
Thank you.<br>
<br>
Regards,<br>
<br>
