Lantunnel is a self-hosted mesh networking tool that connects remote devices across different LANs without requiring port forwarding or public URLs. It uses an end-to-end encrypted protocol to establish direct peer-to-peer connections, falling back to an encrypted relay only when direct traversal fails. You can use their hosted gateway for a zero-config setup or run the entire stack yourself under an Apache 2.0 license.
It is a practical utility if you frequently need to access home servers or office hardware from external networks. The primary drawback is that the easiest setup route requires creating a platform account, which might be a non-starter if you prefer total infrastructure independence. It is an effective alternative to traditional VPNs for those who value direct connectivity over complex firewall configuration.
