A small circle in front of each peer on your Hamachi list is a status indicator. The color of this indicator reflects the status of the connection between you and a peer.
A gray indicator means that the peer is offline and there is no connectivity with it.
A blinking green indicator means that the peer is online and Hamachi is working to establish a connection. It typically takes under a second to establish the tunnel, but sometimes it may take up to few minutes.
A solid green indicator means that you have direct connection with a peer.
A cyan(blue) indicator means that Hamachi was not able to establish direct connection and that you are connected to a peer via a relay server.
Additionally, red status means that you are blocking all network traffic to/from this peer. This block can be toggled via a right-click menu.
If you receive a Relayed Tunnel (Cyan indicator), you may need to set a static TCP or UDP port for Hamachi to use when accepting connections. This is generally necessary when you have a computer behind a router or NAT device and its support of NAT is poor. In this case, you would need to set up a static port forward on the router/NAT, and then fix a static port in Hamachi.
For Port Fowarding, please note that every device is different, and very detailed info per device can be found on PortForward.com
. If you are setting up port forwarding, it is recommended to set them up for both TCP and UDP protocols, and to keep them the same number.
On the Hamachi client, click System > Preferences > Settings.
If you are in the Basic Settings view, click the Advanced Settings link at the bottom.
Scroll down to the Peer Connections section, and enter the port values you set up in your port forward settings of the router/NAT in the Local TCP Address and Local UDP Address.
You do not need to enter an IP Address, just the port number into the short box. See note below
You do need to enter an IP Address if you have more than one active internet connection. Enter the IP Address of the Local adapter you wish Hamachi to connect through.
