-Using the `--permanent` argument will ensure the firewall rules persist reboots. If only IPv4 blocking is used for the Pi-hole installation, the `dhcpv6` service can be removed the the commands below. Create a new zone for the local interface (`lo`) for the pihole-FTL ports to ensure the API is only accessible locally. Finally `--reload` to have the new firewall configuration to take effect immediately.
