Hamachi Relayed Tunnel to Direct Tunnel Fix: The Ultimate Guide to Boosting Speed
Introduction: The Frustration of the "Yellow Eye"
For years, LogMeIn Hamachi has been the go-to VPN solution for gamers, remote IT administrators, and small business owners. It offers a zero-configuration virtual LAN (VLAN) that makes networking across the internet feel local. However, there is one phrase that strikes fear into the heart of every Hamachi user: "Relayed Tunnel."
When you see a "Relayed Tunnel" status next to a peer (often indicated by a yellow icon instead of a green one), your connection speed drops from up to 50 Mbps (Direct) to roughly 500 Kbps (Relayed). This lag makes gaming impossible, file transfers painfully slow, and remote desktop sessions unresponsive. hamachi relayed tunnel to direct tunnel fix
The holy grail of Hamachi optimization is achieving a "Direct Tunnel." This article provides a comprehensive, step-by-step fix to convert your Relayed tunnels into Direct tunnels, dramatically improving latency and throughput.
Part 2: Diagnostics – Are You Really Relayed?
Do not rely solely on the icon color. You need to verify the connection path. Hamachi Relayed Tunnel to Direct Tunnel Fix: The
- Hover over the peer’s name in the Hamachi client. It will explicitly say "Direct tunnel via UDP" or "Relayed tunnel via server."
- Run a Latency Test:
- Right-click the peer > Ping. Direct tunnels should show < 100ms. Relayed tunnels often show > 200ms or timeouts.
- Check the Hamachi Log:
- Navigate to
%appdata%\LogMeIn\Hamachi\(Windows) or/var/log/logmein-hamachi/(Linux). - Search for the peer's nickname or IP. Look for lines containing "relay" or "direct". A direct negotiation log will show
UDP hole punching successful.
- Navigate to
Once confirmed you have a yellow/relayed status, proceed to the fixes below, ordered from easiest to most technical.
2) Check local firewall
- Allow Hamachi through the firewall:
- Windows: Open Windows Defender Firewall → Allow an app → enable “LogMeIn Hamachi” (both Private & Public).
- Or add inbound/outbound rules for UDP/TCP ports Hamachi uses (UDP 12975, UDP 32976 and dynamic UDP/TCP).
- On Linux/macOS, ensure ufw/iptables or pf rules allow Hamachi interface (usually ham0) traffic.
Part 6: Verification – How to confirm you fixed it
Once you apply the fixes, verify your work. Part 2: Diagnostics – Are You Really Relayed
- Hamachi UI: Next to the peer’s name, look for Direct tunnel.
- Speed Test (Internal): Transfer a 100MB file. A Relay tunnel will max out at ~300KB/s. A Direct tunnel will use your full upload bandwidth (e.g., 10MB/s+).
- Latency Check:
- Ping your peer’s Hamachi IP.
- Relayed latency: 100ms+ (often 200-300ms).
- Direct latency: Your actual internet RTT (e.g., 15ms if local).
