Idle Time
Select the number of minutes to elapse without activity before the L2TP connection is

DDNS

Dynamic DNS (DDNS) is a system for allowing an Internet domain name to be assigned to a
varying IP address. This makes it possible for other sites on the Internet to establish connections
to the server without needing to track the IP address themselves. A common use is for running
server software on a computer that has a dynamic IP address (for example, a dialup connection
where a new address is assigned at each connection or a DSL service where the address is
changed by the ISP occasionally). To implement Dynamic DNS, you must set the maximum
caching time of the domain to an unusually short period (typically a few minutes). This prevents
other sites on the Internet from retaining the old address in their cache, so that they have to
contact the name server of the domain for each new connection. Some "client" programs
operate in the background and check the IP address of the computer every few minutes. If it has
changed, then it sends an update request to the service.
The router provides pre-configured settings to commonly used DDNS services, such as
www.dyndns.org, zoneedit, noip, DtDNS, or 3322.org. You should first register with a DDNS
service and obtain an account. This is for users with a dynamic IP from their ISP or DHCP server
that would still like to have a domain name. The Dynamic DNS service provider provides a
password or key to be entered here.
