Access Remote PC

Remotely working on office or home PC over the Internet has received wide market acceptance. While VNN provides other remote access functions like Home NAS sharing, Home Camera access, iTunes Sharing, you can use the same VNN account to access your home or office PC.

Compared with other hosted remote PC access services, VNN provides the direct tunnel between your PC and your home/office PC. This not only brings the total access control back to you but also helps you to avoid the potential network congestion at peak time.

As an application transparent, secure tunnel product, VNN supports all the popular remote desktop software, including pcAnywhere, the open-source VNC, Microsoft Windows' built-in Remote Desktop, etc. While these remote desktop software works well on a LAN, it does not work natively over the Internet.

On the Internet, two issues make things complicated. The first issue is that not everyone receives a fixed public IP address from their Internet access provider. The second issue is that most people access the Internet from behind some kind of NAT router so to have no public IP address. Without the public IP address, the remote desktop software does not know where to establish the connection.

VNN creates a virtual network tunnel between the users, even they use dynamic IP addresses and behind routers. For each PC running VNN, it will be assigned a fixed private IP address. To remotely login to a PC, just needs to enter the PC's VNN IP address in the "Connect To" field. For example, in Microsoft Remote Desktop UI, enter the VNN ID to connect as below:

To access your home PC from office, you can right-click My Computer of your home PC and enter the configuration GUI below. From this GUI, you can tell your home PC to allow other PC to login to it. Based on VNN's access control policy, only the PC with the same VNN account can access each other.

On your office PC, you can press Start->Programs->Accessories->Communication->Remote Desktop Connections, and then get into the following GUI:

The steps for pcAnywhere or radmin, etc. are about the same.

Access Remote PC Via Built-in VNC

VNN-4 includes the open source version VNC. When VNN is installed, the VNC client and server software are also included.

The steps to use the built-in VNC are as below:

1. Run VNN on both PCs.
2. On the PC that needs to be accessed, click "Configure":

Then you will see:

From the other PC, you can click the VNN ID of this PC and first you will see the VNC is not enabled:

After the VNC is enabled, you will see the VNC is in the Enabled state:

Now you can click the "Access" to login to that remote PC.

How to choose whether using VNC or Remote Desktop

If you want the remote user see what you do on that PC, you should use VNC. Otherwise, you should consider using Remote Desktop.

In general, Remote Desktop is more stable and faster than VNC.
