WireGuard Protocol Encryption Protocol

WireGuard VPN Protocol Encryption Protocol for Linux OS

​

WireGuard is the secret sauce that makes your “member node at home” vision work without fighting with ISP routers or static IPs. Think of it as:

• VPN 2.0 → modern, leaner, faster than OpenVPN/IPSec.
• Key-based only → every node has a private/public keypair (no passwords).
• Always-on tunnel → your CrowPi at home will automatically connect into your private network the moment it has internet.
• Fixed internal IP → each member device gets a stable internal address (like 10.77.23.8), even if their ISP changes their public IP.

Why WireGuard?​

1. NAT punching solved
   • Members don’t need to open ports or have public IPs. WireGuard peers use UDP hole punching, so it just works behind most home routers.
2. Lightweight
   • About 4,000 lines of code (vs hundreds of thousands in OpenVPN). Auditable, small attack surface.
3. Speed
   • Uses Linux kernel crypto primitives. Often faster than OpenVPN or IPSec.
4. Static, Private Mesh
   • You can predefine the “Ring” network:
     • Flynn = 10.77.0.10
     • Moses = 10.77.0.11
     • NodeHQ = 10.77.0.1
   • Everyone sees everyone else, even across continents, as if on the same LAN.

WireGuard itself has no monthly cost — it’s completely free and open-source (licensed under GPLv2). You don’t pay WireGuard, because it’s just software.


Where costs show up is in how you host and coordinate the network:

---

1. DIY (zero monthly cost)​

• HQ node: Run WireGuard on your own Raspberry Pi at home or office.
• Member nodes: Each Pi runs WireGuard and connects to HQ.
• Cost: $0 (beyond your electricity + internet you already pay).
• Limitation: If your HQ node loses power or ISP connection, the mesh is down.

---

2. Cloud-hosted coordinator​

• Rent a VPS (virtual private server) to be the “anchor” for your mesh.
• Typical choices:
  
  • Hetzner Cloud CX11 – ~$4–5/month
  • DigitalOcean / Vultr / Linode – ~$5–6/month
  • AWS Lightsail – ~$5/month for basic tier
• You install WireGuard or a control plane like Headscale (open source).
• This gives your Brotherhood always-on, globally reachable entry point.
• Cost: usually $5–10/month total, regardless of how many members.

---

3. Managed VPN providers (optional, not needed if you DIY)​

• Some companies sell WireGuard-based VPNs (NordVPN, Mullvad, Tailscale).
• Tailscale itself is free up to 3 users, ~$5/user/month for larger groups.
• These simplify setup but add monthly subscription fees.

---

So:

• If you self-host → $0/month.
• If you want reliability with a VPS anchor → ~$5/month flat, no matter if you have 2 or 200 members.
• If you buy a managed service → $5–10 per user per month.

Would you like me to price out an exact Brotherhood setup (say, HQ in the cloud + 10 members at home) with a breakdown of $/month?

How members actually connect​

• At HQ (your master Pi or cloud VM) you run a WireGuard coordination server (or Headscale/Tailscale if you want automation).
• Each member Pi gets a wg0.conf file:

[Interface]<br>PrivateKey = &lt;member-private-key&gt;<br>Address = 10.77.23.8/32<br><br>[Peer]<br>PublicKey = &lt;hq-public-key&gt;<br>Endpoint = hq.yourdomain.com:51820<br>AllowedIPs = 10.77.0.0/16<br>PersistentKeepalive = 25<br>

• Result:
  • Flynn at home can ping Moses’ Pi by 10.77.0.11.
  • Your apps (Syncthing, NATS, backups, Python jobs) all use this private IP space.
  • Zero exposure to the public internet.

---

Tie-in with your “domain per member” idea​

• WireGuard gives you the IP backbone.
• You then layer on CoreDNS(or just /etc/hosts) to map:
  • flynn.node.ring → 10.77.23.8
  • moses.node.ring → 10.77.0.11
• Now you don’t need to remember IPs. Each member has their own “domain,” but private-only.

If you want external/public domains, you’d put a reverse proxy at HQ that terminates TLS and forwards through the WireGuard tunnel to the right Pi.

---

Bottom line:
WireGuard gives every brotherhood node a permanent, encrypted identity and a fixed address inside your invisible mesh. That’s how the ecosystem talks securely, no matter what ISP or country they’re on.


Do you want me to sketch out a step-by-step “first node online” guide (install WireGuard, make keys, connect HQ + 1 member), so you can light up your CrowPi as the prototype?
