Exposing SSH, database ports, or admin panels directly to the public internet is one of the most common ways dedicated servers get compromised. A VPN closes that exposure: instead of opening ports to the world, you open them only to devices connected through an encrypted tunnel.
WireGuard operates at the kernel level on Linux, meaning connection setup and throughput are noticeably faster than userspace VPNs like OpenVPN. Setting this up on a Bare Metal Server gives WireGuard a dedicated network stack with no noisy-neighbour contention.
Step 1: Install WireGuard
Ubuntu 24.04 ships WireGuard in the default repositories:
bash
sudo apt update
sudo apt install wireguard -y
