Self Hosted VPN with Tailscale
Having your own VPN can be useful for bypassing geo-restrictions and censorship, as your IP address is that of the exit node. Your traffic is also encrypted and this protects you against sniffing attacks when using public WiFi.
However most VPN services are paid. So if you have a physical server/VPS running somewhere, why not use that?
Tailscale is an awesome open-source VPN service which lets you create a secure peer-to-peer network between your devices. It's built on the open-source Wireguard protocol which is faster than the IPsec and OpenVPN protocols.
