Hamachi Relayed Tunnel To Direct Tunnel Fix Verified Guide

A "Relayed Tunnel" (blue dot) in Hamachi indicates that a direct peer-to-peer connection could not be established, forcing traffic through LogMeIn's relay servers, which significantly increases latency

The following steps cover the most common fixes to achieve a Direct Tunnel (green dot): 1. Allow Hamachi Through Windows Firewall

A common cause is the firewall blocking the "Hamachi Client Tunneling Engine". Control Panel System and Security Windows Defender Firewall Allow an app or feature through Windows Defender Firewall Change settings hamachi relayed tunnel to direct tunnel fix

Part 1: Understanding the Enemy – What is a Relayed Tunnel?

To fix the problem, you must understand Hamachi’s network logic.

1. Check Current Connection Status

  • Open Hamachi → hover over the peer’s name.
  • If it says “Relayed tunnel”, proceed.

3. Add Firewall Rules (Windows Defender or Third-Party)

Hamachi needs inbound/outbound UDP on port 12975 (or 12974–12976 range). A "Relayed Tunnel" (blue dot) in Hamachi indicates

Windows Defender Firewall (Advanced):

  1. Open Windows Defender Firewall with Advanced Security.
  2. Create Inbound Rule → Port → UDP → Specific port: 12975 → Allow the connection.
  3. Create the same as an Outbound Rule.
  4. Also allow hamachi-2.exe and HamachiClient.exe in both inbound/outbound.

Third-party (e.g., Kaspersky, Bitdefender): Add Hamachi as a trusted application and allow UDP 12975. Open Hamachi → hover over the peer’s name

Method 4: Adjusting Network Adapter Priority

If you have multiple network adapters (e.g., a WiFi card and a Hamachi Virtual Adapter), Windows might prioritize the wrong one for routing, leading to connection errors.

  1. Press Windows Key + R, type ncpa.cpl, and hit Enter.
  2. Press Alt to bring up the menu bar,

Fixing a Hamachi relayed tunnel (indicated by a blue dot) to a direct tunnel (green dot) typically involves resolving firewall restrictions, restarting services, or configuring port forwarding to allow direct peer-to-peer communication.

Here are the most effective fixes based on common solutions: 1. Fix Windows Firewall Exceptions

The most common cause is the Windows Firewall blocking the Hamachi client.
