I have recently set up a VPN server in my room. VPN stands for Virtual Private Network which makes it possible to connect to the servers in my room from outside through the Internet as if it is a local area network. It is often described that VPN is just like a private tunnel built in the Internet. It is very secure because making a hole on the tunnel wall is a very tough work. It is true that security requires some costs and in this case, the network speed is traded off with the security. However, I am living in one of the happiest areas in the world in which the ultra high-speed Internet is provided for a reasonable price and now the trade-off of VPN is no longer the problem. I tried to enjoy watching movie and music in Mac Mini in my room from outside using my note PC connected via the wireless Internet. The experiment is successful and I could enjoy the movie and music as if I were in my room.
