Sometimes the background Windows service responsible for managing Hamachi tunnels encounters a glitch. Restarting it forces the client to re-evaluate the connection state. Press Windows Key + R , type services.msc , and press .
This tells the client to prefer that port for direct connections.
Enter 10 or 1 in the text box (a lower number commands higher priority). Click OK on all windows to save the configuration. Step 4: Configure the Hamachi Service Properties hamachi relayed tunnel to direct tunnel fix
Hamachi relies on Universal Plug and Play (UPnP) to open the ports required for P2P connections automatically. If UPnP is disabled on your router, Hamachi defaults to a relayed tunnel.
Click .
Verify that your internet connection is stable and working correctly.
A "Relayed Tunnel" in LogMeIn Hamachi means your connection is bouncing through Hamachi's servers instead of connecting directly to your peer. This extra step introduces severe latency, high ping, and sluggish data transfer speeds, disrupting gaming servers and remote desktop connections. This tells the client to prefer that port
A relayed tunnel is almost always a symptom of network interference. Hamachi is highly dependent on the User Datagram Protocol (UDP) to create its direct P2P pathways. If this process is blocked, Hamachi will default to the relayed connection as a fallback. The common culprits include:

A "Direct Tunnel" is the goal. It establishes a peer-to-peer (P2P) connection between computers for the fastest possible speeds and lowest latency.
