6.Select LAN as the Destination and type the IP address of the computer on your local network that you want to allow the incoming service to. This will not work with a range of IP addresses.
7.Type the port or range of ports that are required to be open for the incoming service.
8.Click Apply and then click Continue.
Note: Make sure DMZ host is disabled. Because the TM-G5240 uses NAT (Network Address Translation), you can only open a specific port to one computer at a time. For example, if you have two Web servers on your network, you cannot open port 80 to both computers. You will need to configure one of the Web servers to use port 81. Now you can open port 80 to the first computer and then open port 81 to the other computer.
