![]() ![]() The VPN address can be an arbitrary private network IPv4 address, the only rule to follow (if you want to avoid extra routing work) is that they must have the same network prefix, just like a typical LAN. Each instance will run on a separate Linode:īefore getting started, it’s a good idea to make a cheat sheet for yourself listing each node’s public IPv4 address, desired VPN address, VPN network name designation, and tinc-daemon name. This is a straightforward setup involving only two instances, an application server (which we’ll call appserver) and a database server ( dbserver). There are no active firewalls on any server.Įach server is connected directly to the Internet (no router or proxy is involved).Įach server is running the same version of tinc.Ī typical use case for a two-node tinc is web-based invoicing software, where the database should be on a separate server (for security and disaster recovery), and needs to communicate sensitive data to the application server through the internet. In order to focus on tinc configuration, three assumptions are made: Update your packages: sudo apt update & sudo apt upgrade Please ensure you have access to privileged user rights. This guide will use sudo wherever possible. Complete the following steps for each one:įollow the Setting Up and Securing a Compute Instance guide to create a standard user account, harden SSH access and remove unnecessary network services. ![]() You will need at least two Linodes for this guide. The design allows tinc users a great deal of flexibility, especially when planning a mesh-type network.įrom a clear two-server connection to complex mesh private network, this guide will show you how to configure tinc VPN in three different use-case scenarios. All VPNs behave as a secure tunnel between two points, but tinc stands out for its “Peer-to-Peer” design. There are many open-source VPN options but one of them shines above the others: tinc. Virtual Private Networks (VPN) are an essential part of any serious network security deployment plan.
