In this document we are going to try to describe all the steps we will need to connect a Linux machine to a VPN that is offering a Fortigate, in this case an IPSEC VPN. A post that I hope does not harbor much mystery.
In this document, we'll look at the configurations needed to connect an iPad or iPhone device to a FortiGate IPsec VPN, with this we will be able to make the corporate applications of our iPad/iPhone work directly, ideal for putting on a softphone-type application and calling (or receive calls) directly from such devices, saving the costs of calls or being 100% Available,
IPSec is a network traffic encryption protocol. In this procedure I do a test of how to encrypt communications between a client PC (XP) and a server (2003). The server 2003 has the IP 192.168.0.3 and has FTP server enabled, the thing is that the XP is connected to the FTP server to download some files, but between those two PCs there is a 'kapuyo'’ With a sniff, and since FTP traffic and almost everything on the network is unencrypted then the 'kapuyo’ has taken out the password with which the XP has been authenticated in the 2003, all this happens in the same network, in the same domain (XP and 2003 At least). In order for all traffic to the server to be encrypted I will enable the IPSec services and on the client also to talk to each other in 'IPSec'.
This procedure explains how to connect two separate networks using a VPN between two Fortigate. The example is based on the following image:
This procedure explains how to set up a VPN using IPSec to connect to any PC from the internet to your organization's LAN. All traffic would be encrypted using IPSec. To connect to the VPN we will do it through the software “FortiClient”. Two parts are explained:
