## What it means

Peers exchange encrypted traffic according to configured keys and routes. A successful handshake confirms a tunnel relationship, not that every application uses the intended path.

## For hosting

Use one key per device, protect private keys and test forwarding, DNS and firewall rules. Revoke lost peers promptly.

## Can one lost device be revoked independently?

Use a distinct peer key for each device and retain an understandable peer inventory. Shared keys make targeted revocation and incident review harder.
