A LINUX VPN CONNECTION WILL ALLOW YOU TO JOIN TWO OR MORE BRANCHES OF YOUR BUSINESS OVER THE INTERNET.
This type of connection provides security and confidentiality, since no one can “see” what is transferred from one side to another. The biggest uses of VPN are:
- Connect a remote PC to the main office
- Join two remote branches as if they were one
- Make employees and suppliers can connect to the main office from their homes.
- Among other uses …
There are different VPN technologies, however, one of the most used is OpenVPN. Unlike other solutions, OpenVPN provides data compression , which means that, in addition to being encrypted, the data is compressed while traveling over the network, making the connection faster.
OpenVPN is a free software based solution, that is, no licenses are paid for it, which encrypts the information based on SSL certificates. Similar to those used to enter the bank’s website. This is installed on a server in the company which will allow access by the user or the remote network.
WORK FROM HOME
VPN is the best option for those who work from home. With this resource you have access to both the applications and the main system, as well as the company’s shared files.
The VPN connection avoids the need for an office or parking space. On the other hand, more collaborators can be included in the working group. Virtual offers teamwork more flexibility for workers and businesses.
SECURITY IN THE COMPANY
The VPN connection allows secure access to the company network, everything you send or receive, through the Internet, will be encrypted and compressed, thus reducing the possibility of intrusion into the network.
CONNECT TO THE OFFICE FROM YOUR LAPTOP
You only need to install the VPN application on your laptop, to be able to connect to the office in a transparent and secure way.
Fully transparent to existing infrastructure Our system is transparent to any infrastructure already implemented in your network.
Transparent to users Network users will not notice any changes, nor will there be modifications to their PCs.
Technology based on Free Software You will not have to pay for expensive licenses of implemented software.
Data compression, online The OpenVPN solution compresses the data while it is being transmitted, this makes the VPN much faster, thus optimizing internet bandwidth for other applications.
No dedicated hardware is required. It is not necessary to buy expensive devices to connect the networks, just the Linux server connected to the internet.
Increase in network security Data transmitted from one office to another is encrypted and compressed, using technology based on free and standard free software, optimizing the available bandwidth.
High network scalability If you need more remote offices, it is possible to add them to the current Virtual Private Network without this constituting changes in the way users work.
Flexible and fast installation and implementation The implementation is carried out quickly, its users will not notice its implementation, except for the new network that will be seen from one location to another.
Layer 2 and Layer 3 OpenVPN VPNs offer 2 basic modes, which run as a Layer 2 or Layer 3 VPN. Therefore OpenVPN tunnels can carry Ethernet frames, IPX packets and Windows (NETBIOS) packages, all these packages are known issues in other VPN solutions.
Supports Proxy Configuration OpenVPN has proxy support, and can be configured as a TCP or UDP service, as a server or as a client, OpenVPN simply waits for connection requests according to its configuration.
HOW DOES IT WORK?
A VPN server is implemented in each remote office, this in turn will link to the other offices through another VPN server similar to the one implemented in your office, in this way, when you require information from the remote office, it will be sent and received as if all the PCs were in the same office.
WHAT DO I NEED TO HAVE MY VPN WORKING?
To make this connection it is necessary that in each place you have a quality Internet connection. Additionally, it is required that there is a CPU with 1GB of memory and 80Gb hard disk in Linux that makes the VPN link to the other network (s).
The VPN server will securely encrypt and compress the information by sending it to the desired remote site, all this transparently to users and as if they were all in the same place.
