How dev-mir2011/ufwui works
UFWUI is a Flask web interface and JSON API for managing a Linux host’s UFW firewall. The main workflow is a browser viewing firewall status and rules, then enabling/disabling the firewall or adding/deleting rules through the API; API handlers delegate those operations to helpers that invoke the host’s ufw command. The README also documents privileged, host-network deployment with /etc/ufw mounted. The HTML template was not sampled, so its detailed rendering behavior is not represented.
