Item Description 
Enable  Check this box to enable such port redirection setting. 
Mode  Two options (Single and Range) are provided here for you to 
choose. To set a range for the specific service, select Range. 
In Range mode, if the public port (start port and end port) 
and the starting IP of private IP had been entered, the 
system will calculate and display the ending IP of private IP 
automatically. 
Service Name  Enter the description of the specific network service. 
Protocol  Select the transport layer protocol (TCP or UDP). 
WAN Interface  Select the WAN IP used for port redirection. There are eight 
WAN IP alias that can be selected and used for port 
redirection. 
The default setting is All which means all the incoming data 
from any port will be redirected to all intefaces. 
Public Port  Specify which port can be redirected to the specified Private 
IP and Port of the internal host. If you choose Range as the 
port redirection mode, you will see two boxes on this field. 
Type the required number on the first box (as the starting 
port) and the second box (as the ending port). 
Source IP  Use the drop down list to specify an IP object. Or click IP 
Object link to create a new one for applying. 
Private IP  Specify the private IP address of the internal host providing 
the service. If you choose Range as the port redirection 
mode, you will see two boxes on this field. Type a complete 
IP address in the first box (as the starting point). The second 
one will be assigned automatically later. 
Private Port  Specify the private port number of the service offered by the 
internal host. 
After finishing all the settings here, please click OK to save the configuration. 
Note that the router has its own built-in services (servers) such as Telnet, HTTP and FTP etc. 
Since the common port numbers of these services (servers) are all the same, you may need to 
reset the router in order to avoid confliction. 
For example, the built-in web user interface in the router is with default port 80, which may 
conflict with the web server in the local network, http://192.168.1.13:80. Therefore, you 
need to change the router’s http port to any one other than the default port 80 to avoid 
conflict, such as 8080. This can be set in the System Maintenance >>Management Setup. You 
then will access the admin screen of by suffixing the IP address with 8080, e.g., 
http://192.168.1.1:8080 instead of port 80.
