Firewaller

A simple way to mass whitelist incoming traffic from specific ip addresses (Currently only made for FirewallD).

Backstory

I needed a way to mass-whitelist incoming traffic from IPs on a specific port from Cloudflare (https://www.cloudflare.com/ips/), TCPShield (https://tcpshield.com/v4-cf/) and so on and I was to lazy to copy and paste the ips myself.
