Hamachi Relayed Tunnel To Direct Tunnel Fix _best_ -

How to Fix Hamachi "Relayed Tunnel" and Switch to Direct Tunnel

2.2 Desired State: Direct Tunnel

• Definition: Data travels directly from Client A to Client B without an intermediary server.
• Indicators:
  • Connection status says "Direct Tunnel" (green dot).
  • Ping times typically < 50ms (depending on geographic distance).

Step 1: The Quick Wins (Software Configuration)

A. Disable IPv6 on the Hamachi Adapter This is the single most effective fix for "Stuck on Relay."

1. Press Win + R, type ncpa.cpl.
2. Find the Hamachi Network Interface.
3. Right-click > Properties.
4. Scroll down to Internet Protocol Version 6 (TCP/IPv6).
5. Uncheck the box > Click OK.

B. Kill the Relay via Context Menu Sometimes Hamachi misreports. Force a re-handshake:

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.

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

To fix the problem, you must understand Hamachi’s network logic. hamachi relayed tunnel to direct tunnel fix

5) Force re-establishment of tunnels

• In Hamachi client, right-click the peer → “Repair client” (or “Reconnect”).
• If that option not present: disconnect and reconnect the peer, or reboot both clients.

Why Does a Relayed Tunnel Happen?

Hamachi falls back to a relayed tunnel when a direct connection fails. Common causes:

• Strict NAT on one or both sides (common with mobile hotspots, CGNAT, or corporate networks).
• Firewall/Antivirus blocking Hamachi’s direct traffic.
• Multiple network adapters causing routing confusion.
• ISP-level restrictions (e.g., double NAT).
• Hamachi’s "Direct traffic" setting disabled.

Part 5: When All Else Fails – Alternative Solutions

Let’s be realistic: Hamachi is legacy software. LogMeIn has not significantly updated its NAT traversal engine in nearly a decade. If the "Hamachi relayed tunnel to direct tunnel fix" remains elusive after two hours of work, migrate to modern alternatives: How to Fix Hamachi "Relayed Tunnel" and Switch

| Feature | Hamachi | ZeroTier | Tailscale | | :--- | :--- | :--- | :--- | | NAT Traversal | Weak (Relay heavy) | Excellent (STUN + UPnP) | Excellent (DERP relay fallback) | | Speed | Slow UDP relay | WireGuard (Fast) | WireGuard (Fast) | | Tunnel Type | Relayed (default) | Direct (default) | Direct (default) | | Setup | Simple | Moderate | Very Simple |

Migration Command: Install ZeroTier, create a network, have your peers join. You will get a Direct Tunnel instantly without any of these fixes. Definition: Data travels directly from Client A to

Step 2: Disable IPv6 (Surprisingly Effective)

Hamachi’s IPv6 relay detection is buggy on many networks. Forcing IPv4 often solves the problem.

On Windows:

1. Open Control Panel → Network and Sharing Center → Change Adapter Settings.
2. Right-click your Hamachi adapter → Properties.
3. Uncheck “Internet Protocol Version 6 (TCP/IPv6)”.
4. Click OK. Restart Hamachi.

On macOS/Linux: Disable IPv6 system-wide temporarily for testing (sysctl -w net.ipv6.conf.all.disable_ipv6=1).
