Hamachi Relayed Tunnel To Direct Tunnel Fix Jun 2026

If you are on a corporate or school network, the admin may block relay.logmein.com (port 443) or UDP to external IPs.

: UDP hole punching typically expects traffic to route through public IPs. When both devices share the same public IP (because they’re on the same router), the connection logic sometimes fails, causing the router to treat each direction of communication as a separate session.

Create a new port forwarding rule with the following details: Hamachi UDP External Port: 41001 Internal Port: 41001 Protocol: UDP Device/IP Address: Enter your specific IPv4 Address . Create a second rule: Application Name: Hamachi TCP External Port: 41002 Internal Port: 41002 Protocol: TCP Device/IP Address: Enter your specific IPv4 Address . Save the settings and reboot your router. 3. Enable UPnP (Universal Plug and Play) hamachi relayed tunnel to direct tunnel fix

| Color | Meaning | |-------|---------| | | Peer is offline | | Blinking Green | Attempting to establish a connection | | Solid Green | Direct tunnel established (optimal) | | Blue / Cyan | Relayed tunnel connection (suboptimal) | | Red | Traffic is blocked between peers |

Hamachi sometimes struggles to establish direct tunnels when IPv6 is enabled on its virtual adapter. Stay in the window ( ncpa.cpl ). If you are on a corporate or school

You must do this on both peers’ routers if both are behind strict NATs.

This comprehensive guide will explain exactly why this happens and provide step-by-step instructions to fix the "Hamachi relayed tunnel" issue, forcing your connections to become faster, more reliable, . Create a new port forwarding rule with the

Click . Click Change settings at the top right. Locate LogMeIn Hamachi in the list. Check both the Private and Public boxes next to it. Click OK to save. Step 3: Set Static Listening Ports in Hamachi

Relayed tunnel. Traffic is routed through LogMeIn servers. High latency.

This is the most reliable fix. You are telling your router: “Let UDP traffic on port 12975 through to my PC.”

. This means your connection is being routed through Hamachi's servers rather than connecting directly to your friend, leading to high latency and slower speeds.
