OpenWrt firewall4 UCI rule
How it works
Imports only canonical Firewall Rule Builder JSON and renders one documented OpenWrt firewall4 (fw4) config rule stanza. Enter a UCI rule name and zones locally: input rules need a source zone, output rules need a destination zone, and forward rules need both. IPv4, IPv6, and address-free inet rules map to firewall4 families. Connection states, log prefixes, interface matches, comments, and multiple address or port matches are rejected because this compact UCI subset cannot represent them exactly. Nothing is executed, saved, or applied.
