Linode VPN Setup and Configuration Guide

To set up a VPN on Linode, you'll need to create a new Linode instance and configure the OpenVPN server software. Linode offers a range of instance types to choose from, including dedicated CPU instances and shared CPU instances.

For this guide, we'll be using the shared CPU instance type, which is a cost-effective option for most users. You can choose the instance type that best fits your needs and budget.

Once you've created your Linode instance, you'll need to configure the network settings to allow incoming VPN connections. This involves setting up a static IP address and configuring the firewall rules to allow incoming traffic on the OpenVPN port.

To access the Linode dashboard, simply log in to your Linode account and click on the "Linodes" tab to view your instance list.

Setting up a VPN on Linode is a straightforward process, thanks to Meshnet's routing capability that simplifies traditional VPN configurations.

To start, you'll need to deploy a Linode instance, which can be done with scalable resources and a variety of global data center locations.

The process of setting up your own VPN server enhances your online privacy, giving you more control over your IP address.

However, it's worth noting that setting up your own VPN server may not provide the same level of protection as connecting to a standard VPN server offered by NordVPN.

You'll need to secure SSH access with key-based authentication, which can be done by installing the NordVPN app.

Linode's global data center locations allow you to migrate servers between data centers, providing flexibility and reliability for your VPN server.

Linode VPN provides a secure connection through OpenVPN protocol, which encrypts data in transit with AES-256 encryption.

This encryption ensures that even if your data is intercepted, it will be unreadable to unauthorized parties.

OpenVPN also supports various encryption algorithms, including AES-128, but AES-256 is recommended for maximum security.

This level of encryption is particularly important for sensitive information, like financial data or personal identifiable information.

Linode VPN's secure connection also includes Perfect Forward Secrecy (PFS), which generates a new encryption key for each session.

This prevents hackers from using a compromised key to access your data in the future.

PFS is a critical component of Linode VPN's security features, providing an additional layer of protection against cyber threats.

To configure a VPN on Linode, you'll first need to sign the root certificate using the StrongSwan Server on Debian 11. Replace CN with your VPN server name.

The root certificate will be used to generate the StrongSwan Server private Certificate. You'll need the ca.cert.pem file for future use.

By default, the Linux kernel disables packet forwarding between internal and external interfaces. You can edit the /etc/sysctl.conf file to make changes.

For basic configuration, such as logging level and policy, you can leave the default settings in the ipsec.conf file.

To set up client configuration for your Linode VPN, you'll need to generate client certificates and build .ovpn files using EasyRSA and the ovpn_getclient script.

The client certificates will be stored in the $OVPN_DATA/pki/issued/ directory.

For Linux and Mac users, it's essential to modify the .ovpn file to edit the remote DNS entry if you plan to deploy multiple VPN instances.

Here's a rough breakdown of the scripting environment for client configuration:
