WireGuard Architecture Notes#

This seed article establishes the future structure for a practical WireGuard architecture reference. It is intentionally concise in the first release, but it keeps the shape of the final article visible.

Scope#

Peer identity and public key mapping
AllowedIPs as both routing policy and access boundary
Site-to-site, remote access and hub-and-spoke patterns
NAT traversal and endpoint roaming
Operational risks around key rotation and route leakage

Future Notes#

The complete article should compare WireGuard with IPSec and SSL VPN designs, then document operational practices for routing, monitoring and incident response.
