The Frostwall Protocol — GRE Tunnel Security Architecture
Time: 3-4 hours
Status: DEPRIORITIZED — March 14, 2026
Priority: LOW — no active DDoS problem, email unblocked via Billing VPS
Documentation: docs/tasks/frostwall-protocol/

Custom DDoS protection using GRE tunnels from Command Center to TX1/NC1. Hides real IPs, protects email reputation.

Why urgent now: Email is needed soon — Holly staff email, staff comms, subscriber notifications. Frostwall → Mailcow is the only path to get there. This is the critical blocker.

Core Components:

  • GRE tunneling (encrypted links)
  • 1-to-1 NAT/DMZ forwarding
  • Iron Wall UFW rules
  • IP hierarchy (scrubbing → backend → binding)

Blocks: Mailcow (email) → Holly email, staff email, subscriber comms, all Tier 2+ infrastructure
Deployment doc: https://docs.google.com/document/d/12Kh-AhUgJLOJrBgIjMiGi3xRZH1basRz
