DDNS
These settings are only necessary when the gateway is set up behind an Internet sharing device that
uses a dynamic IP address and does not support DDNS.
You need to apply for an account with a DDNS service from www.dyndns.org before you type in the
following information.
• Server address: Sets up the IP address or URL (Uniform Resource Locator) of the DDNS Server.
• Hostname: The URL of the system (or NAT) – apply from domain name registration providers (e.g.
www.dyndns.org).
• Login ID and Password: The ID and password are used to log into the DDNS server.
• Behind NAT: Select only when the system is set up behind a NAT device.
NOTE: If the gateway is set up under NAT, then enter the hostname into the NAT
IP/Domain that is the same with Hostname of DDNS.
