Everyone in this thread: PHP sucks because it was bad when I last used it 20 years ago.

Those haven’t existed in PHP anymore for a very long time.

Well better late than never.

Thats what the firewall rules do too, don’t allow internet connection if there’s no vpn connection.

Firewall is a system-wide solution that always works, while qbt config relies heavily on the application implementing interface binding properly. Which it doesn’t fully btw.

Better to just configure a firewall properly so that no packets can go outside of the vpn tunnel.
