With the development of broadband Internet access technology, it is easy to move and share data, and in fact, users who share their data through the Internet are increasing day by day. The types of data that users want to share were also small data based on text and still images at first, but the desire to share large amounts of multimedia data such as music files and videos is increasing day by day.

In order to meet the requirements of these users, broadband connection with symmetrical up / down speeds of DOCSIS 2.0 cable modem, VDSL, etc. is used in internet access technology where downlink speeds such as cable modem (DOCSIS1.0) and ADSL are important. Technology has emerged.

As such, infrastructure including Internet access technology continues to develop, and prices of mass storage devices such as hard disks continue to fall, and P2P (Peer to Peer) based Internet storage devices using such internet infrastructures and hard disks are continuously developed. It is becoming. These Internet storage devices are mainly connected to cable modems and xDSL modems, which are high-speed Internet, and Internet users can use them to upload or download large-capacity multimedia files on the Internet at a very low cost.

Internet speeds have increased with the development of broadband access technology, but the lack of public IP remains. Therefore, it is too expensive to give a public IP to Internet-enabled devices such as PCs, IP set-top boxes and network printers in SOHO environments or at home.

One solution to this problem is to use NAT (Network Address Translation) devices such as IP routers in many places. NAT device exists between the external network and the internal network, which translates the address of the data coming from both networks. One or several public IPs are used for the external access network, and internal private IPs are used. Internet devices on the internal network receive private IP from NAT devices and access the Internet through NAT devices. Increasingly, in many SOHOs and homes, IP routers, a type of NAT device, are connected to broadband modems such as cable modems, ADSL modems, and VDSLs, and have been assigned private IPs from IP routers.

Conventional Internet storage device is made to be operated using a public IP. Therefore, there are two ways to install / operate the conventional internet storage device in the environment using NAT. The first is to replace your NAT device with an Internet storage device that has NAT capabilities. The second method is to use the port forwarding function included in the NAT function. The first is possible because many Internet storage devices have NAT capabilities. However, this method is reluctant to replace the NAT device used by most users, and it is difficult to expect that the NAT function of the Internet storage device performs better than the NAT function of the NAT device in use. The second method is possible by knowing the IP and port number used by the Internet storage device and applying it to the NAT configuration. Such a change in NAT setting is practically possible only by the owner of considerable network knowledge, and it is difficult to use given that most users of Internet storage devices are SOHO or the general public at home.
