Hamachi’s engine responds to ARP requests for remote Hamachi IPs with its own MAC address (proxy ARP), then tunnels the Ethernet frame. This makes the virtual network behave like a local Ethernet segment.
The tunneling engine operates by adding a virtual network interface to your computer. It intercepts outbound traffic from your OS, encrypts it using AES 256-bit encryption , and delivers it to a destination peer over a specialized UDP connection.
