Configuring Dynamic DNS
A dynamic DNS service provides a central public database where information (such as e-mail
addresses, host names and IP addresses) can be stored and retrieved. The dynamic DNS server also
stores password-protected information and accepts queries based on e-mail addresses.
If you want to use a dynamic DNS service, you must register for it. The dynamic DNS client
service provider will give you a password or key.
Note: For information about port forwarding and port blocking, see
“Firewall Rules—Port Forwarding and Port Blocking” on page 3-5.
