The Hamachi "peer problem" is a common error that occurs when the VPN service cannot establish a direct connection between two computers. You will usually see a yellow warning triangle next to a friend's name or a "tunneling problem" status in the LogMeIn Hamachi client. Quick Fixes to Try First Before diving into deep system settings, try these basic steps: Restart everything: Close Hamachi and restart your computer. Ask your peer to do the same. Update the client: Ensure both users are running the latest version of Hamachi. Check the power: Ensure the "Power" button in the Hamachi UI is blue (on). Disable the Windows Firewall The most frequent cause of the peer problem is the Windows Defender Firewall blocking the incoming VPN traffic. Open the Control Panel and go to System and Security . Click on Windows Defender Firewall . Select Turn Windows Defender Firewall on or off . Switch it to Off for both Private and Public networks. Check Hamachi. If the light turns green, you need to add an "Exception" for Hamachi rather than keeping your firewall off permanently. Change Hamachi Service Settings Sometimes the LogMeIn Hamachi Tunneling Engine service gets stuck or lacks the permissions to bridge the connection. Press Win + R , type services.msc , and hit Enter. Locate LogMeIn Hamachi Tunneling Engine . Right-click it and select Properties . Go to the Log On tab. Select Local System account and check the box Allow service to interact with desktop . Go back to the General tab, click Stop , then click Start to refresh the service. Configure Advanced Peer Settings If the connection is still yellow, you may need to manually adjust how Hamachi handles peer-to-peer traffic. Open Hamachi and go to System > Options . Click on Settings and then Advanced Settings . Under Peer Connections , set Peer VPN Alias to None . Find IP Protocol Mode and set it to Both or IPv4 Only . Look for Filtering and set it to Block Traffic: None . Restart the application. Use a VPN Content Bypass (Encryption) In some cases, your ISP or local router might be blocking Hamachi traffic because it recognizes it as VPN data. In the Advanced Settings menu (mentioned above), look for Peer Connections . Find Encryption and set it to Enabled or Always . Find Compression and set it to Disabled (this can sometimes help stability). Common Status Indicators ⚠️ Yellow Triangle: The most common "peer problem." It means a relay tunnel is being used because a direct connection failed.🔵 Blue Circle: You are connected via a "Relayed Tunnel," which causes high latency (lag).🟢 Green Circle: The connection is healthy and direct. If you'd like more help, let me know: Are you seeing a yellow triangle or a red icon ? What operating system are you using (Windows 10, 11, or Mac)? Is this happening with all peers or just one specific person?
Report: Solving the Hamachi Peer Problem What is the Hamachi Peer Problem? When using LogMeIn Hamachi for a virtual private network (VPN), the "peer problem" typically refers to one of these symptoms:
Peers show as "Blocked" instead of "Online" Peers are "Offline" despite being connected to the internet Unable to ping peer IP addresses File sharing or game hosting fails even though everyone is in the same Hamachi network hamachi peer problem
Primary Causes | Cause | Explanation | |-------|-------------| | Firewall blocking | Windows Defender, third-party AV, or router firewall blocks Hamachi traffic | | Network adapter issues | Hamachi virtual adapter disabled or corrupted | | IP conflicts | Two peers assigned the same Hamachi IP | | Proxy/VPN interference | Another VPN or proxy service conflicts with Hamachi | | Outdated client | Mismatched versions across peers | | Relay mode | Unable to establish direct peer-to-peer tunnel, falling back to slower relay |
Step-by-Step Troubleshooting Guide 1. Check Hamachi Status Icons
Green circle = Direct tunnel (best) Blue circle with arrows = Relay tunnel (works but slow) Red circle with slash = Blocked (fix needed) Gray = Offline Select the war
If blocked : Focus on firewall and adapter settings. 2. Disable/Configure Firewalls Windows Defender Firewall:
Go to Control Panel → System and Security → Windows Defender Firewall → Allow an app through firewall Ensure Hamachi has both Private and Public checked If missing, manually add: C:\Program Files (x86)\LogMeIn Hamachi\hamachi-2-ui.exe
Third-party antivirus (Norton, McAfee, Bitdefender, etc.): instead of "
Temporarily disable firewall feature If that fixes it, add Hamachi as an exception
Router firewall (advanced):
