2.  Configure the following settings below. When done, click 

Apply.

•    Enable Port Forwarding: Choose Yes to enable Port 

Forwarding.

•    Famous Server List: Determine which type of service you 

want to access.

•    Famous Game List: This item lists ports required for popular 

online games to work correctly.

•    FTP Server Port: Avoid assigning the port range 20:21 for 

your FTP server as this would conflict with the router’s native 

FTP server assignment.

•    Service Name: Enter a service name.
•    Port Range: If you want to specify a Port Range for clients 

on the same network, enter the Service Name, the Port 

Range (e.g. 10200:10300), the LAN IP address, and leave the 

Local Port empty. Port range accepts various formats such 

as Port Range (300:350), individual ports (566,789) or Mix 

(1015:1024,3021). 

•  When your network’s firewall is disabled and you set 80 as the HTTP

server’s port range for your WAN setup, then your http server/web 

server would be in conflict with the router’s web user interface.

•  A network makes use of ports in order to exchange data, with each

port assigned a port number and a specific task. For example, port 80 

is used for HTTP. A specific port can only be used by one application 

or service at a time. Hence, two PCs attempting to access data 

through the same port at the same time would fail. For example, you 

cannot set up Port Forwarding for port 100 for two PCs at the same 

time.
