[arch-general] Fail2Ban is not adding iptables rules

Hi, I have this script for iptables for my archlinux desktop: https://pastebin.com/SafhsKFt And when received external request access SSH error, fail2ban add rule but the rule not working. I think it has to do with the iptables script, but the fail2ban blocking rules add fine but don't ban. That could be happening?
