firewalld block /all ip

i use the firewalld GUI

i tried block certain ports/service i am not using especially once that can connect to my Fedora workstation remotely like FTP/SSH

now by leaving the IP address section source/destination blank it set the firewall Rule as /Any IP address ?

so the Rule is block [lets say port 21] from any IP address.
