The Firewall acquires its IP address through DHCP. Through DDNS service provided by www.3322.org,
the Firewall informs the DNS server of the latest mapping between its domain name and IP address.
The IP address of the DNS server is 1.1.1.1. The Firewall uses the DNS server to translate www.3322.org
into the corresponding IP address.
