Hamachi Relayed Tunnel To Direct Tunnel Fix

While there are no major peer-reviewed "academic papers" exclusively dedicated to fixing a relayed tunnel in

1) Confirm basics

• Ensure both peers are online in Hamachi and show unique IPv4 addresses (25.x.x.x).
• Temporarily disable any VPNs or proxy software.

6. Test with a Different Network (if possible)

If one peer switches to a less restricted network (e.g., mobile hotspot), that often forces direct tunnel. While there are no major peer-reviewed "academic papers"

• In the Hamachi Preferences -> Settings, check "Enable UPnP".
• Ensure UPnP is enabled in the Router settings (usually under Administration or Advanced Networking).
• Note: UPnP is less secure but automates the port forwarding process.

• Find your friend’s Hamachi IP (e.g., 25.10.20.30).
• Run as Admin in CMD:
  route add 25.10.20.30 mask 255.255.255.255 <your_own_Hamachi_IP> metric 1 -p

1. In the Hamachi client, right-click the peer showing "Relayed."
2. Click "Copy IPv4 Address" (to keep it in clipboard).
3. Right-click the peer again > "Details..." > Close the box.
4. Open Command Prompt (cmd) and type ping [paste IP here] -t.
5. Watch the Hamachi UI. It often flips to "Direct" within 10 seconds.
