UFW (Uncomplicated Firewall) on a Mac
Easy iptables/nftables host firewall for Linux servers (manage over SSH) · Routers & Firewalls
UFW is the friendly front-end to iptables/nftables on Debian/Ubuntu Linux servers — simple allow/deny rules (ufw allow 22/tcp), default policies and logging. It's Linux-only (macOS uses pf — see the Security pane), so manage it on a linked Linux server over SSH: ufw status verbose, ufw enable, ufw allow . Use the server's Run Command box or a script. Pairs with fail2ban for brute-force protection.
