DDNSC is a service which provides automatic Dynamic Domain Name updates. It is particulary useful when used in conjuction with UPnP_Portfwd to access the LAN Turtle
directly from the outside.\n \n
You would need to register the hostname in any of the supported DDNS providers (see /usr/lib/ddns/services) and update the configuration with your info.\n \n
Example:\n \n
Service: no-ip.com\n
Hostname: turtle.ddns.net\n
Username: your@email.com\n
Password: yourpassword\n \n
