Tutorial: Securing Access to and from Remote Systems with WireGuard and Linux
summary
Hands-on demo sets up a Linux WireGuard gateway VM using the wg-quick helper script, generates keypairs, and applies iptables NAT/post-up rules and IP forwarding to expose a private web and file server via private DNS. A workstation config with allowed-IPs triggers a handshake, traffic counters increment, and the browser reaches the internal site—so it works. Also shows split- vs full-tunnel, persistent-keepalive for NAT traversal, router plugins (MikroTik), and using Netmaker coordination server to automate key distribution.
