ufw-reset

ufw [--dry-run] [--force] reset

ufw reset disables Uncomplicated Firewall and restores it to the installation defaults. It is a ufw subcommand, not a separate binary.The command removes the rules you added, reloads the default policies, and leaves the firewall disabled. After a reset, enable it again with ufw enable and add rules with ufw allow, ufw deny, ufw reject, or ufw limit.

Requires root or sudo. A reset deletes existing ufw rules. On a remote host this can lock you out once you enable the firewall again unless you add SSH (or another management) rules first. --dry-run shows the planned change; --force skips the confirmation prompt.
