This article explores a practical approach to creating a virtual LAN for NAS devices using P2P hole punching and transparent gateway techniques. The author details the implementation process, including how to bypass NAT restrictions to enable direct peer-to-peer connections. Performance test results are provided, comparing latency, throughput, and reliability against traditional VPN solutions. The method is particularly useful for remote access to home NAS systems without relying on centralized servers. Key technical aspects include UDP hole punching, STUN server integration, and transparent proxy configuration. The article also discusses limitations and optimization strategies for different network environments. For developers and self-hosting enthusiasts, this offers a cost-effective alternative to commercial remote access services.
