Download Radmin VPN 2.1 for free in Thai. This program simulates a Local Area Network (LAN) using a Virtual Adapter and a VPN network with AES-256 encryption, allowing peer-to-peer connectivity without port forwarding. This is the latest version.

What is Radmin VPN?

Radmin VPN It's a program that simulates a Local Area Network (LAN), allowing multiple computers to connect to the internet via a single network for gaming and remote file sharing without configuring routers or opening ports. It works by installing a Virtual Network Adapter driver in the Windows networking system and assigning a unique virtual IP address to each host. This allows the operating system to see the destination hosts as if they were connected to the same physical switch. The internal architecture uses packet encapsulation protocols (TCP, UDP, and ICMP) with AES-256 encryption to secure the data payload during transmission over the internet.

The data transmission mechanism uses a peer-to-peer connection employing UDP hole punching techniques to bypass NAT and firewalls of routers. This allows computers to create a direct tunnel and communicate without port forwarding or enabling UPnP on network devices. If the network structure is a symmetric NAT that cannot be penetrated, the system automatically switches routes through a relay server. It also supports broadcast and multicast transmission for host discovery in LAN games and network applications.

System administrators can create a mesh network and configure access control via network passwords. The software integrates with Radmin Server and Radmin Viewer via a virtual IP for immediate access to Remote Desktop, file transfer, and Telnet, and can be used in conjunction with other system environment management programs.
