As such, Hamachi2 will try to broker a connection between peers over TCP 443 (non-SSL)Īnd lastly, Hamachi2 will try a relayed connection over TCP 443 (non-SSL) before giving the user a message that the peer is unreachable. In some environments, a hardware firewall is used to block traffic on specific ports, but not protocols. If UDP direct and relayed methods fail, it is somewhat unlikely that TCP connectivity will work, however, Hamachi2 will try it. If UDP direct connectivity cannot be established, Hamachi2 will try to initiate a relayed UDP connection. UDP uses random ports by specification, so it is not possible to open a single port for peer connections for UDP.

By default, Hamachi2 will broker a peer connection over UDP. Peer connectivity has several methods and ports.

If the above ports cannot be used to achieve a connection, Hamachi2 will try again using SSL (TCP 443). Hamachi2 uses several ports to achieve connectivity to the mediation servers, and to peers. Try following the port forwarding instructions at the bottom of this document. If you receive a relayed tunnel, it can be caused by a failure to negotiate a port for the data connection. Which ports and protocols does LogMeIn Hamachi2 use? This block can be toggled via a right-click menu. A yellow indicator means that Hamachi2 failed to establish both direct or relayed connection with a peer.Īdditionally, red status means that you are blocking all network traffic to/from this peer. A cyan down-pointing arrow is the same as the previous type, except that it indicates the use of low-speed relay.Ħ. A cyan indicator means that Hamachi2 was not able to establish direct connection and that you are connected to a peer via a high-speed relay.ĥ.

A solid green indicator means that you have direct connection with a peer.Ĥ. It typically takes under a second to establish the tunnel, but sometimes it may take up to few minutes.ģ. A blinking green indicator means that the peer is online and Hamachi2 is working to establish a connection. A gray indicator means that the peer is offline and there is no connectivity with it.Ģ. The color of this indicator reflects the status of the connection between you and a peer.ġ. What do the different color indicators mean in LogMeIn Hamachi2?Ī small circle in front of each peer on your Hamachi2 list is a status indicator.
