AWS Openvpn

OpenVPN can traverse firewalls and NAT firewalls, allowing you to establish a VPN connection even from restricted networks.

Here is a high-level overview of how you can set up OpenVPN on AWS:

1. **Set Up AWS Infrastructure**: Create an EC2 instance in your desired AWS region. Ensure that the security group attached to this instance allows for inbound traffic on the port you’ll use for the VPN connection (default is 1194 for OpenVPN).

2. **Install OpenVPN**: SSH into your EC2 instance and install the OpenVPN server. The installation process may vary depending on the operating system of your EC2 instance.

3. **Configure OpenVPN**: After installation, you’ll need to configure OpenVPN by setting up certificates and keys, defining network settings, and configuring VPN client settings.

4. **Start OpenVPN Server**: Once configuration is complete, you can start the OpenVPN server. Make sure to set it up to start on boot, so it’s always available.

5. **Connect to VPN**: On the client-side, you will need to install the OpenVPN client software and provide it with the client configuration file generated on the server. Once everything is set up, you can initiate a VPN connection.

6. **Testing**: After setting up, ensure you test the VPN connection from the client-side and make sure that all your network routes are working correctly.

Remember that AWS also offers its managed VPN service, AWS VPN, which lets you easily establish a secure and private tunnel from your network or device to the AWS global network. AWS VPN is comprised of two services: AWS Site-to-Site VPN and AWS Client VPN. For some use cases, it may be more efficient and easier to use these managed services rather than setting up your own OpenVPN server on an EC2 instance.
