If you're seeing the "ACL not found: Safe_ports" error in OPNsense Squid, it means the Safe_ports rule is missing from your config. Just add this line to your squid.conf:

yaml

acl Safe_ports port 80 443 21 70 210 1025-65535


Then make sure it's referenced like this:

yaml

http_access deny !Safe_ports

Restart Squid after saving. For easier proxy management, services like lightningproxies.net can help streamline things.

I had the same issue pop up suddenly, and after some digging, I found out my network was being hit repeatedly by an IP Stresser. Once I tweaked the firewall rules a bit, the alerts stopped. I'd also run a packet capture during those events to get a clearer picture of what's going on.

I think it could be interesting to integrate AI into OPNsense, but I wouldn't say it's something that can just happen overnight. OPNsense is all about network security, right? So, adding AI could make sense for things like intrusion detection or improving traffic management. AI could potentially help in recognizing patterns and threats more efficiently, kind of like how it's done in advanced firewalls or other security systems.
That said, it would require some serious effort to make it work smoothly, and you'd need to weigh the performance impact. Also, the community would need to get involved in developing something like this. If you're curious, check out some AI-driven network security tools on suprai.io  for inspiration.
