    Custom firewall-start script for OpenVPN (country allow list)

Together with a --down custom script which removes the custom firewall rule and ipset. Thanks for the tip! I choose tcp/443 because that's the only port...

    The words printer and laserjet are an automatic translation of well known ports. Printer = tcp/515 and laserjet is tcp/9100. If you do a netstat -ln you will see the associated ports. Not 100% sure what they are for but I believe it's for the Network printer service.
