I have two VPS running in the cloud. The first one is the database, and another one is the web server. I want to secure traffic that flows between private network which is insecure by design and I do not want to use OpenVPN due to complex settings. How do I install and setup tinc VPN server and secure my traffic over VPN on Ubuntu Linux 16.04 LTS server?
