This repository contains a configuration of a FortiGate 40F with an dialup IPsec VPN set up for a small office or home office. The screenshots of configuration steps in the GUI can be found in the steps.md file
Background information on lab concepts can be found in the respective write-up, which is located here: https://101zh.github.io/networking/
The purpose of this lab is to configure a FortiGate 40F firewall with a secure IPsec remote access VPN, so that a remote client can initiate a tunnel connection to the firewall. Additionally, remote desktop protocol was configured on one of the lan PCs to simulate a practical use of a VPN in an office workplace.
In this lab, a FortiGate 40F firewall was configured as a dial-up VPN server for remote FortiClient users. This allows the users to initiate a tunnel connection with the FortiGate, so that LAN resources can be accessed. In this case, the remote client will use remote desktop protocol to take control of PC 1, demonstrating a practical use of a VPN.
This Topology is for IPv4. All 10.0.0.xx addresses are for the user LAN.
- One FortiGate 40F running v7.2.10
- This is later updated to v7.6.6
- One Cisco 3560 POE-38 running C3560-IPSERVICESK9-M Version 12.2(44)SE5
