Aggressive firewall rules are the leading cause of relayed tunnels. You must explicitly allow Hamachi through your security software.
Remember that some situations—like being behind CGNAT or having incompatible router configurations—may make direct tunnels impossible. In those cases, the relayed tunnel is Hamachi’s fallback mechanism ensuring you can still communicate (albeit with higher latency).
需要一篇关于将Hamachi中继隧道转为直接隧道修复问题的长文。这个问题涉及技术原理、诊断方法和解决方案，信息需求比较综合。先并行搜索几个方向：官方文档或社区关于中继隧道与直接隧道的说明、导致中继的原因、修复技巧，以及防火墙和NAT相关的通用网络配置信息，看看能覆盖多少。出来了，信息比较丰富。有几篇看起来很有针对性：一篇来自Appuals的通用修复步骤，一篇来自LogMeIn官方文档解释中继隧道原因和端口转发要求，还有一篇详细的博客文章（sbzsystems.com）提供了具体的操作步骤。另外，关于颜色指示符的官方页面解释了中继隧道（蓝色）和直接隧道（绿色）的区别。先打开这几篇，把故障原因、诊断方法和具体操作步骤都理清楚。打开的几篇文章提供了不少信息。现在需要更系统地了解常见修复方法，比如禁用/启用连接、重启服务、重装驱动这些基本步骤，以及UPnP、端口转发等网络配置技巧。为了全面覆盖，再搜几个相关的关键词组合，比如“Hamachi relayed tunnel fix”、“UPnP port forwarding Hamachi direct tunnel”、“Hamachi blue dot fix”，看看有没有更具体的步骤或社区讨论。收集得差不多了，涵盖了故障现象、技术原理和从基础到进阶的各种修复方法。文章的结构可以这样安排：先解释什么是中继隧道以及它为什么会出现，然后分析主要原因，接着分多个层次提供详细的解决方案，从最简单的软件设置到高级的网络配置，最后给出预防建议。引用方面，Appuals和LogMeIn官方文档提供了基础步骤和端口信息，sbzsystems和Arch论坛的文章则补充了防火墙设置和静态端口配置的方法。 How to Fix Hamachi Relayed Tunnel and Switch to Direct Tunnel Connection hamachi relayed tunnel to direct tunnel fix
You’ve set up your LogMeIn Hamachi network. All the nodes are green. You can ping each other. But when you try to transfer a file, play a LAN game, or access a remote desktop, it feels like wading through molasses. You check the Hamachi status window and see two dreaded words next to a peer: .
This guide outlines the technical reasons behind relayed tunnels and provides step-by-step solutions to force a direct connection. Aggressive firewall rules are the leading cause of
: Yes, alternatives include ZeroTier, Tailscale, and SoftEther VPN. However, Hamachi remains popular due to its simplicity and zero-configuration approach. Many of the troubleshooting principles in this article (port forwarding, firewall exceptions, static ports) apply to these alternatives as well.
Under , look for Local UDP address and Local TCP address . In those cases, the relayed tunnel is Hamachi’s
Scroll down in the list to find . Right-click the service and select Restart .
Hamachi needs (default).
To help pinpoint why your connection is still failing, tell me:
As one user observed, when the same person connected from home instead of from the office network, the connection automatically became a direct tunnel—confirming the issue was router-specific.
