RSOCKS : A method to traverse NAT for mobile applications

In this paper we introduce our new protocol, RSOCKS which enables Internet client to access to the server in the guarded network inside NAT/FW. There are some methods to solve this problem, including the port forwarding and SOCKS. However these protocols assume the situation that the server application is installed a server computer and fixed to the network. In the future it is thought that the application servers are installed to mobile terminals or non-PC equipments. The conventional methods are not always suitable for such situation. RSOCKS enables the application installed mobile terminals traverse NAT and expose it to the Internet securely.
