At the end of last year, many IT media in Japan reported a free software. This is the software called Softether. In short, this software is to simulate the working order of the Ethernet card, and even simulate the Hub function to use the Tunnel feature to implement the VPN function. Make the system completely identify this software into a network card
With this thing, you can no longer buy a VPN router, and achieve the goal of accessing your own LAN from the Internet.
Mainly achieved: 1) Software simulate network communication on OSI Level2 (Data Link Layer), put the physical layer communication content package to TCP Package (Software Simulation Ethernet) 2) Turn your own communication package into SSL session , Cross the Internet with HTTPS protocol, even mixed FireWall (128bit RC4)
However, there is no two days, Japan Information Processing Association (IPA, responsible for Japan Internet Operation Management / Security) requires this university student to stop opening this procedure, the reason is natural: With this thing, you can not Exaggerated, all LANs under all FireWall are facing major security challenges, because as long as there is a machine in the intranet to pass this software virtual into the LAN network card, you can access the intranet through the Internet. ......terror
In the above implementation ideas, the first one does not become a legal crime, and it has become a bare excuse.
However, the ban maintains only three or four days, IPA has to agree to this person once again openly download homepage.
I have experienced such a wind wave, and the Softether is more famous. Interested friends may wish to download a play
Install this, you need to have LAN's management. For example, the LAN of your own, you can safeize the function of accessing your own Server from the Internet; and the unit's LAN is the one.

It seems to be so terrible, this is the same as HTTP Tunnel, what can be scared? HTTP Tunnel has been published in this mode, or it is necessary to connect to it. After the NAT address, there is no way to cross. The good place to do this is to simulate a physical network card, in addition to this, no new idea. The problem is to simulate the network card, not innovation, think about VMware

I am still in research, so there is no reason to persuade you so much than other tools, huh. :)
