Show HN: Ranet3 – High performance policy routed IPsec mesh SD-WAN

📝 Discussion Summary (Click to expand)

Key Themes in the Discussion

Achieving stable IPv6 despite ISP limits
Users are interested in how to obtain reliable IPv6 when their providers lack native support.

“I'd really like to know what you did to get stable v6. My ISP is also limited in a similar way - no IPv6.” – evanjrowley
“i happen to have v6 address allocation, im using the ranet3 to directly route v6 traffic to nearest bgp exit node” – StepBroBD
Licensing and openness concerns
The current license is seen as restrictive, prompting worries about adoption, with plans to relax it later.

“Looks cool until I saw the license which is clearly not an open-source license.” – adulau
“yeah... im thinking of moving the license to a less restrictive one when i can better feed myself currently its source available and auto converts to apache 2 after 2 years” – StepBroBD
Future roadmap and business aspects
The author envisions a mature control plane/web UI, a low‑cost or free tunnel broker, and is seeking YC support.

“in the near future, when the tool is more mature (namely control plane and web ui), i’ll potentially open up a low cost (or hopefully free) tunnel broker” – StepBroBD
“ranet3 is in the yc winter batch application pool, if you happen to be an investor, lmk i’d be happy to give you a demo!” – StepBroBD

🚀 Project Ideas

Generating project ideas…

Provides a control plane and web UI for operators to run their own IPv6 tunnel broker, giving users IPv6 connectivity over existing IPv4 ISP links.
Core value proposition: open‑source, easy‑to‑deploy service that mimics public tunnel brokers (like Hurricane Electric) but lets anyone host it for free or low cost.

Key	Value
Target Audience	ISPs, hosting providers, tech‑savvy individuals who want to offer IPv6 tunnels
Core Feature	Web‑based portal to create/delete tunnels, automatic nearest‑exit‑node selection via anycast/GeoIP, WireGuard backend
Tech Stack	Go (control plane), React/TypeScript (UI), PostgreSQL, WireGuard, Docker
Difficulty	Medium
Monetization	Revenue-ready: $5/mo per active tunnel (hosted SaaS) or Hobby for self‑hosted

HN users expressed frustration with missing IPv6 (evanjrowley) and interest in a low‑cost tunnel broker (StepBroBD) – this directly satisfies that need.
Open‑source licensing addresses adulau’s license concerns; the project can start source‑available and transition to Apache 2 after a set period, encouraging community adoption.

A lightweight daemon that runs on user devices/routers, detects lack of native IPv6, and automatically establishes a tunnel to a configured broker (e.g., IPv6Broker) with minimal user input.
Core value proposition: zero‑config IPv6 connectivity for end‑users, handling route setup, DNS64/NAT64, and keep‑alive.

Key	Value
Target Audience	End‑users, home network admins, small businesses whose ISP lacks IPv6
Core Feature	Auto‑detect IPv4‑only link, negotiate tunnel via broker API, configure WireGuard interface, install routes
Tech Stack	Rust (daemon), libwireguard, systemd service, JSON config, optional GTK/UI for desktop
Difficulty	Low
Monetization	Hobby (open‑source) – could be bundled with router firmware for revenue

Commenters wanted a simple way to get stable v6 without manual configuration (evanjrowley); this agent removes that friction.
The agent can work with any broker, fostering ecosystem interoperability and discussion around best practices for tunnel automation.

Provides real‑time monitoring, alerting, and automatic failover for IPv6 tunnels, showing latency, packet loss, and throughput per exit node.
Core value proposition: ensures reliable IPv6 service by switching to the best‑performing tunnel endpoint without manual intervention.

Key	Value
Target Audience	Tunnel broker operators, network admins, power users relying on IPv6 tunnels
Core Feature	Metrics collection (Prometheus exporter), Grafana dashboards, alert rules, automatic DNS/route failover
Tech Stack	Prometheus, Grafana, Go exporter, Redis for state, Kubernetes (optional)
Difficulty	Medium
Monetization	Revenue-ready: $10/mo per broker instance (hosted) or Hobby for self‑hosted

HN discussion highlighted desire for mature control plane and web UI (StepBroBD); v6watch adds the missing observability layer.
By offering transparent health data, it builds trust in community‑run brokers and encourages more users to adopt IPv6 tunnels.
