Dynamic DNS (DDNS) automates the process of advising DNS servers when the automatically assigned IP address for a network device is changed, ensuring that a specific domain name always points to the correct machine. The domain name tracks the dynamic address so that other users on the Internet can easily reach the domain, allowing you to host a website, FTP server or email server, even when your IP address is dynamic.
GTAís Dynamic DNS service allows you to connect your dynamic IP address from DHCP, PPP, PPPoE or PPTP by selecting one of these services from the dropdown menu: DynDNS at www.dyndns.org or ChangeIP at www.changeip.com. The currently used External IP address on the GTA Firewall will update to the selected service each time the IP address changes, or once every month, whichever comes first. To sign up for DDNS services from one of these providers, and for more information about using Dynamic DNS, see the providerís website.
