5.7 Setting up Virtual Private Networks (VPNs)

A Virtual Private Network (VPN) is a computer network that uses a public network such as the Internet to transfer private data. VPN users can exchange data just like in an internal LAN. VPN are often used by companies as a way of providing access to the company network to staff when they are out of the office. The process involves the FSG establishing a VPN connection to the company's VPN gateway. Using this connection, the employee is then able to perform his duties as if he/she were working directly in the company's local area network.

Open Connections -> VPN -> ADD Connection in the main menu.

Status

You can enable or disable the VPN connection at any time here.

Name

Please enter any name of your choosing for the connection here.

Remote Host IP

In this field, please type in the IP address of the VPN routers that you wish to connect to (you need to have an account on this router).

Remote Network

Enter the IP address and the network mask that you want to access. Example: 192.168.1.0/

24.The '0' at the end of the IP address signifies that you can reach any PC in the network under the IP addresses 192.168.1.1 – 192.168.1.254. /24 indicates that this is a network mask 255.255.255.0. If the network you are attempting to access contains several subnets with the net mask 255.255.252.0, please enter /22 in place of /24.

ESP Encryption

This is where you set the encryption protocols. You can keep the default settings, although they have to be supported by the remote machine.

ESP Encryption 3Des

Triple DES (3DES) is an advanced version of the Data Encryption Standard (DES). The old DES only used key lengths of up to 56 bits. 3DES on the other hand uses three encryption cycles and two or three keys. By using three keys, an actual key length of 112 bits is provided.

MD5

MD5 sums are used by PGP and other programs to check the integrity of files. This involves comparing the file's current MD5 sum with an accepted sum from earlier. This allows the system to determine whether the file has been changed or is corrupt.
