2. If your WAN IP address starts and ends with 
0.0.0.0, it means all hosts in WAN can implement 
remote Web management. If you change the WAN 
IP address as 218.88.93.33-218.88.93.35, then 
only the IP addresses as 218.88.93.33, 
218.88.93.34 and 218.88.93.35 can access the 
Router. 
 
For example:   
If you want to configure the IP address 218.88.93.33 to 
access the device’s web interface, please set it as 
above.

Chapter 11 Routing Settings 
 
11.1 Routing Table 
 
The main duty for a router is to look for a best path for 
every data frame, and transfer this data frame to a 
destination. So, it’s essential for the router to choose 
the best path, i.e. routing arithmetic. In order to finish 
this function, many transferring paths, i.e. routing table, 
are saved in the router, for choosing when needed.
