When you try to access some remote computer,maybe this computer located in a private LAN or this computer are configured to deny your computer's ip address.
For example, Computer A is your own computer and you want to access some service located on Computer D, you must firstly access Computer B and secondly Computer C. Under this situation, maybe you need to go through a lots of computer to finally access the destination. Now, you can deploy this Port Tunnel software on those computers, this will let you directly access computer D easily.
Sometime you want to access some computers behind firewalls, gateways, or routers that you don't have right to configure.
In this case, you can not directly access a local computer located in a private LAN. But if you deploy our port tunnel software on Gateway and set port tunnel, then now you can directly access a local computer from outside.
SSL Tunnel or SSL Port Forwarding is a very important technology to make sure your data is transfered safely, specially when your data must go through internet. But there is a lots of softwares are non-SSL aware. That means when you are using those softwares,your data can be easily be stolen. This is very risky.
Now using Port Tunnel Wizard, you can easily turn those softwares of non-SSL aware into safely softwares by ssl tunnel technology. SSL Tunnel function of Port Tunnel Wizard is very easy to be used and will encrypt network data for you.
From above figure you can see that using Port Tunnel Wizard to encrypt communication data of non-SSL is very simple. What you need to do are just two steps. The first step is deploy Port Tunnel Wizard on Computer A or some computer that in the same network with Computer A and make it run as a SSL client. The second step is just deploy Port Tunnel Wizard on Computer B or some computer that in the same network with Computer B and make it run as a SSL server. Then Port Tunnel Wizard will run as a ssl tunnel to encrypt communication data between computer A and B.
