What is a Virtual Private Network (VPN)? |
| |
A VPN is an electronic mode of communication wherein multiple locations (or sites) communicate as if they were in single location. |
|
What use is a VPN? |
| |
A network is a group of computers connected together. A useful approach as it allows sharing of information, resources and internet connectivity. But such an approach proves costly as an internet connection and specialist security hardware are required.
This concern of having a network together in a cost effective manner raised the development of VPN wherein multiple locations can join together in a cost effective secure and simple fashion.
Such an arrangement will ensure access to your network from any location as effectively as from the office.
For organisations that work from multiple locations, such as regional sales offices, this allows information equipment and resources to be shared between the offices as if they were located in the same building. |

|
Why should I use a VPN rather than using a password protected access to a remote network share?
|
| |
There are several reasons why a VPN should be used, the key reasons are:
- Using a remote network share would mean having to expose a computer/server directly to the Internet. This is always extremely dangerous as it does not restrict access.
- Any data that is transmitted over the Internet would be available to anyone to see as it is transmitted in plain text format. The Internet is made up of many computer networks joined together. As the data passes from network to network to it's destination, it passes through lots of third party networks. If the data is sent just using a remote network share, anyone could read/sniff the data and see what is being transmitted (including the network share password).
A VPN works by having multiple theoretically uncrackable authentication keys that only the VPN server can decrypt. Once the keys have been confirmed, the 'tunnel' is established. Then any data that is sent down the 'tunnel' is encrypted, so the data cannot be intercepted and read. |
|
Can I add more connections to our VPN network ?
|
| |
Once the VPN server has been installed, additional client connections can be easily added. |
|
I currently can share information internally on my network and I have certain ports forwarded on the firewall to allow particular traffic in and out I need to keep this set-up
|
| |
The Global Internet Data Center Networks VPN will be set to match your internal networks and can be configured to replicate any existing port forwards as necessary. |
|
Where exactly does the VPN server sit on my network?
|
| |
The VPN box sits in on the border of you network, directly connected to your Internet connection. The Internet connection comes into the VPN server and then out onto your internal network, with the exception that the firewall component will block and log attempts to get into your internal network by unauthorised users. |
|
I don't want all my Internet traffic to be passing through the VPN, how does the VPN work?
|
| |
When you want to use the Internet, such as to surf the web, the information just flows out through your Internet connection as per normal, however, when you want to place something onto the VPN connected network, the VPN detects where the traffic is directed, and routes it through the encrypted tunnel to the server. |
