PORT FORWARDING 
Use the PORT FORWARDING window to open ports in your router and re-direct data through those ports to a single PC on your network 
(WAN-to-LAN traffic). The Port Forwarding function allows remote users to access services on your LAN such as FTP for file transfers or SMTP and 
POP3 for e-mail. The DSL-2880AL will accept remote requests for these services at your Global IP Address, using the specified TCP or UDP 
protocol and port number, and then redirect these requests to the server on your LAN with the LAN IP address you specify. Remember that the 
specified Private IP Address must be within the useable range of the subnet occupied by the Router. 
 
To access the PORT FORWARDING settings window, click on the PORT FORWARDING button in the ADVANCED tab 
 
PORT FORWARDING RULES CONFIGURATION 
 
Select  an  application  type,  e.g.  FTP,  from  the  Application  Name 
drop-down menu for a pre-defined application to speed up configuration 
or type an application name manually in the Name input box in order to 
define your own application. 
 
Select a name from the Computer Name drop-down menu or type an IP 
address  in  the  IP  address  input  box  to  appoint  the  PC  to  receive  the 
forwarded packets. 
 
The External Port shows the ports opened for remote users in the WAN 
side of the router. The TCP/UDP means the protocol type of the opened 
ports.   
 
The Internal Port shows the ports opened in the PC with the appointed IP 
Address. The TCP/UDP means the protocol type of the opened ports.
