Tutorial: Securing Access to and from Remote Systems with WireGuard and Linux
summary
Sets up a minimal VPN using two Linux VMs and WireGuard, generates keypairs, uses WG-quick helper script to create interfaces, and adds iptables NAT rules (or nftables) and IP forwarding to route a VPC LAN 10.10.1.0/24 through a gateway. Demonstrates client config with private key, server public key, persistent-keepalive, DNS via private resolver, and shows successful handshakes and HTTP access by private DNS. Also covers peer-to-peer mesh tradeoffs and Netmaker for automated key/endpoint distribution.
