Dynamic DNS Settings 1
z Dynamic DNS Settings: Select [Enable] if you wish to activate the DDNS service.
z Device Name: Specify server name. This name setting also used by the DDNS service to recognize each server.
E.g. if configure name as “user” to DDNS address “server.ddns.com”, then this NDC can be accessed by URL
http://user.server.ddns.com after register to the DDNS server.
z DDNS Server Address: Specify address of the DDNS server.
z DDNS Connection Port : Specify the DDNS server listen port, and the default is “80”
z Router Incoming Port: Specify your router listen port for the DDNS server to redirect. The router may configure the
different port for incoming (Internet request) and outgoing (Intranet request), e.g. it may configure to redirect
Internet HTTP (port 80) request to Intranet port 8000, then, in this case, we must configure the “Router Incoming
Port” to 80, and inside the NDC Network settings should set HTTP port with 8000.
z Update Time: Specify the NDC updated frequency in seconds, and the default is 600 (10 minutes), this is interval
that NDC will automatically send an updated packet to the DDNS server.
z DDNS Message: Return messages from remote DDNS server, and some hints may help to diagnostic the reason
if register fails.
♦ DDNS addr. CGI fail:
It means that NDC can’t communicate with Internet world. Make sure your Network Configuration has correct
subnet mask and default gateway, and DNS1 setting is correct and reachable.
♦ Already registered:
Another user had registered this name; please change your register name by changing “Device Name”.
z Apply: Click this button to save the changes made.
