Point to Site VPN Configuration

Step 1: Prerequisites

• Create a private network (VPC) without a router via Horizon.

• Navigate to Project → Network → Networks → Create Network.

• Example: Subnet - 192.168.7.0/24, Gateway IP - 192.168.7.1.

Step 2: Create a Security Group

• Navigate to Project → Network → Security Group → Create Security Group.

• Allow any protocol for the pfSense Server.

Step 3: Create a pfSense Server

• Attach both Public and Private Interfaces (e.g., Server-0).

• Assign the gateway IP.

• Disable port security of the Private Interface.

Step 4: Configure pfSense Interfaces

• Set up the LAN and WAN interfaces inside pfSense Server.

Step 5: Create a Temporary Windows Server

• Create a Windows Server with a private interface (e.g., Server-1).

Step 6: Access pfSense WebGUI

• Log in using the default username and password.

Step 7: Initial pfSense Setup

• Complete the basic setup wizard as shown in the images.

Step 8: Set Up Certificates and OpenVPN Server

• Navigate to VPN → OpenVPN → Servers → Wizards.

• Tunnel Network: 192.168.8.0/24.

• Local Network: 192.168.7.0/24.

• Edit the server settings as needed.

Step 9: Install OpenVPN Client Export Package & Create Users

• Install 'openvpn-client-export' from System → Package Manager → Available Packages.

• Navigate to VPN → OpenVPN → Client Export to download the bundled configuration archive.

• Ensure you have a user account set up with a user certificate created. This can be completed by selecting System > User Manager > Add. Select a username and Password, then click to create a user certificate. Give the certificate a name and ensure that the OpenVPN_CA that we created earlier is selected. Leave the rest as default and save.

Step 10: Set up OpenVPN Client

• On Browser search “OpenVPN Connect Download” and download the “Download.msi” file and install it.

• Launch OpenVPN Connect and upload the configuration file.

• Enter the username and password associated with the certificate.

• Click 'Continue' to establish the connection.

Step 11: Final Testing

• From the OpenVPN client, ping the pfSense LAN IP to verify connectivity.

• Verify VPN tunnel operation (client gets IP from 192.168.8.0/24).

• Ensure correct routing between VPN subnet (192.168.8.0/24) and LAN subnet (192.168.7.0/24).

• Confirm pfSense LAN interface (192.168.7.1) is reachable and responding.
