dynamically join a network, obtain an IP address, convey its capabilities and learn about

other devices on the network. In turn, a device can leave a network smoothly and

automatically.

Select

UPnP

from the

Network Management

menu,

then

UPnP

screen page appears.

2.5.10 DDNS

The WLAN Gateway supports DDNS (Dynamic Domain Name Service). The Dynamic DNS

service allows a dynamic public IP address to be associated with a static host name in any

domains, allowing access to a specified host from various locations on the Internet. This is

enabled to allow remote access to a host by clicking a hyperlinked URL in the form

“hostname.dyndns.org”. Many ISPs assig

n public IP addresses using DHCP that makes it

difficult to locate a specific host on the LAN using standard DNS. For example, when you

are running a public web server or VPN server on your LAN, this ensures that the host can

be located from the Internet if the public IP address changes. DDNS requires that an

account be setup with one of the supported DDNS providers.

Select

DDNS

from the

Network Management

menu,

then

DDNS

screen page appears.

DDNS:

Enable DDNS global setting, if checked.

DDNS Server type:

Select one of the DDNS registration organizations form those listed in

the pull-down menu. Available servers include Dyn.Dns.org and no-ip.com.

DDNS User name:

Enter the username given to you by your DDNS server.

DDNS password:

Enter the password or key given to you by your DDNS server.

Confirmed password:

Re-enter DDNS password.

Host name to register:

Enter the host name of DDNS server.
