Subj : Telnet pc under NAT To : comp.programming From : taranfx Date : Fri Sep 16 2005 11:05 am I am planning to design a VPN application. I am looking for basic concepts involved. Suppose i want to telnet to apc under Dynamic NAT. For this i use a client on this PC so that it initiates an outbound connection. Server on the othern side recieves this request, telnets to the pc. In this scenario, wat shud b the program that opens a socket for the server on the way back connection. Will java sockets will be effective in this case? wat shud be done? .
