How to setup a peer to peer site to site VPN using OpenVPN on pfSense?

Summary

In this article, we will explore the concept of setting up a site-to-site VPN using OpenVPN on pfSense. We will cover the steps required to create a secure tunnel for data communication and allow traffic between networks through routers, firewalls, or internet gateways.

Main Thought

To set up a site-to-site VPN with OpenVPN, you need to first install the OpenVPN client software on a Linux server on the branch network. This client will connect to the OpenVPN Access Server to establish an active tunnel for secure data communication.

Key Points

1. Install the OpenVPN client software on a Linux server on the branch network.
2. Connect the OpenVPN client to the OpenVPN Access Server to establish a secure tunnel.
3. Allow traffic between the networks through routers, firewalls, or internet gateways.

4. Configure the OpenVPN server in pfSense by following these steps:
a. From the pfSense menu, navigate to VPN and OpenVPN.
b. Click on Add to create a new OpenVPN server.
c. Select the server mode based on your requirements.
d. Change the local port if necessary.
e. Provide a description for the server.

5. Generate the required certificates for authentication:
a. Generate the Certificate Authority (CA) certificate.
b. Generate the server certificate.
c. Create an OpenVPN user and user certificate.

6. Create firewall rules to allow traffic between the networks.

7. Install the OpenVPN Client Export Utility to configure client connections.

Questions and Answers

1. Question: How do I set up a site-to-site VPN with OpenVPN?
Answer: Install the OpenVPN client software on a Linux server on the branch network. Connect the client to the OpenVPN Access Server to establish a secure tunnel. Allow traffic between networks through routers, firewalls, or internet gateways.

2. Question: Can OpenVPN be used for site-to-site VPN?
Answer: Yes, OpenVPN Access Server can be configured in a site-to-site bridging setup to transparently bridge two sites together using an OpenVPN gateway client.

3. Question: How do I set up remote VPN access using pfSense and OpenVPN?
Answer: You can set up your own OpenVPN server in pfSense by following these steps: authentication, generating the CA, generating the server certificate, creating the OpenVPN server, setting firewall rules, and installing the OpenVPN Client Export Utility.

4. Question: Is OpenVPN peer-to-peer?
Answer: By default, OpenVPN runs in point-to-point mode but also introduces a new mode called “server” that implements a multi-client server capability.

5. Question: What is the difference between OpenVPN remote access and site-to-site?
Answer: A remote access VPN allows someone remote access to a network they cannot join directly. A site-to-site VPN securely links different networks but is not primarily focused on remote access.

6. Question: What is the difference between OpenVPN site-to-site and client-server?
Answer: Site-to-site VPNs connect entire networks, while client-server VPNs deal with single user connections.

7. Question: How do I configure OpenVPN on pfSense step by step?
Answer: Create the OpenVPN server, select the server mode, change the local port if necessary, and provide a description for the server.

8. Question: How do I set up a peer-to-peer VPN?
Answer: In the Google Cloud console, go to the VPN page, create a peer VPN gateway, provide a name, select the number of interfaces on your physical VPN gateway, and add the interface IP addresses.

9. Question: What is the difference between P2P and site-to-site VPN?
Answer: P2P VPNs create a private connection between two points over the internet, while site-to-site VPNs securely link different networks.

10. Question: What is the difference between site-to-site VPN and peering?
Answer: VPNs connect networks over the internet, while VPC peering links VPCs located in the same or different Amazon accounts.

11. Question: What are the two types of site-to-site VPN?
Answer: The two types are intranet-based VPNs, which connect offices within the same company, and extranet-based VPNs, which connect offices of different companies.

12. Question: How do I set up OpenVPN with an OVPN file?
Answer: Right-click on an OpenVPN configuration file (.ovpn) and select “Start OpenVPN on this configuration file.” Stop it by pressing the F4 key.

13. Question: How do I connect to an OpenVPN server from pfSense?
Answer: Set up the OpenVPN client by logging into the pfSense web interface, navigating to VPN and OpenVPN, and configuring the client settings.

By following these steps and understanding the concepts discussed, you can successfully set up a site-to-site VPN using OpenVPN on pfSense.
