Static IP Security: How to Safely Expose Devices to the Internet

Reachable does not mean unprotected. WireGuard, firewall rules and correct practice for internet-facing devices.

A static public IPv4 makes your device reachable from the internet. Reachable does not mean unprotected. Speedroute uses WireGuard encryption, hub-level firewall rules and per-device key authentication.

The Speedroute security model

Layer What it does Managed by
Tunnel encryption ChaCha20/Poly1305 — all traffic encrypted Speedroute
Authentication Per-device Curve25519 key pairs Speedroute + customer
Port scanner visibility WireGuard silent — no response to unauthenticated packets Speedroute
Inbound port control Hub firewall — restrict on request Speedroute (configurable)
Source IP restriction Restrict to monitoring centre / aggregator IP Speedroute (configurable)
Device credentials Must be changed before deployment Installer

Installer security checklist

Action Why
Change default router password Default credentials are the most common attack vector
Change default NVR password Default NVR credentials are widely exploited
Restrict inbound ports Minimise attack surface
Request source IP restriction CCTV: monitoring centre only. BESS: aggregator only.
Keep NVR firmware current Most compromises exploit known patched vulnerabilities
