This message is returned by the DDNS Server 
Normally, this message should be something like "Update 

successful" or "IP address updated". 

If the message indicates some problem, you need to connect to the 

DDNS Service provider and correct this problem.  

 
 

 
This feature allows you to make Servers on your LAN accessible to Internet users. Normally, 
Internet users would not be able to access a server on your LAN because: 

 
•  Your Server does not have a valid external IP Address. 
•  Attempts to connect to devices on your LAN are blocked by the firewall in this 

device. 

 
The "Virtual Server" feature solves these problems and allows Internet users to connect to your 
servers, as illustrated below. 

 

 
Note that, in this illustration, both Internet users are connecting to the same IP Address, but 
using different protocols.
