Note:
Before changing the listen port, user must add a port directive “:” in browser URL in order to get
correct connection. (i.e. http://<IP>:<Port> , e.g. H http://192.168.0.200:8000 H) to access the device
with IP 192.168.0.200 and port with 8000).
These features enable user to use the device behind NAT or IP Sharing devices which could access
up to 65536 NDC with one IP Address.

– Dynamic DNS Settings
The DDNS (Dynamic Domain Name Service) is used when users want to access the NDC with an easy memorized
name such as http://demo.server.ddns.com instead of http://61.220.235.172. This service could be useful when the
NDC is located behind Dial-up ADSL or IP sharing devices, which does not have fix IP address, then it’s impossible to
reach the NDC from Internet.
When the NDC enables the DDNS service, it will “register” to the DDNS server with its information, such as server
name to access, router virtual port number and updated frequency, etc.
Then NDC automatically “update” to the DDNS server by a fix frequency, so even the IP is changed by ISP, the DDNS
server still could get and update internal database. Then, once users access from Internet with its register name, e.g. if
registering with server name “demo” to DDNS server “server.ddns.com”, the NDC could be accessed by
http://demo.server.ddns.com .
