: It intercepts data packets from the application layer and encapsulates them into secure tunnels using protocols such as OpenVPN.

TAP-Windows 9.21.2 serves as a virtual Ethernet adapter, allowing VPN clients like OpenVPN to establish encrypted tunnels for data privacy. While widely used for its robust support of NDIS 6 (Network Driver Interface Specification), this specific version was released to address bugs found in earlier 9.21 iterations. This paper explores its functionality, security significance, and common implementation challenges. 1. Functional Architecture tap-windows 9.21.2
