Mesh VPNs: How Tailscale and Zerotier Change Networking

Need to access your home PC from a coffee shop? In the past, you'd need port forwarding or a complex OpenVPN setup. Tailscale and ZeroTier make this effortless.

Overlay Networks

These tools create a virtual "LAN" that sits on top of the internet. Every device gets a private IP (e.g., 100.x.x.x) and can talk to any other device as if they were plugged into the same switch.

The Power of WireGuard

By using the WireGuard protocol, these mesh VPNs are incredibly fast and lightweight compared to old IPsec or OpenVPN tunnels.

They also use clever "NAT Hole Punching" techniques to bypass firewalls without you having to open a single port on your router.
