Troubleshooting Connectivity

To the mediation server

Hamachi connects to a central server on ports 12975 TCP, and 32976 TCP. These are destination ports on our server. To permit this activity in a network firewall, something like

ip allow 12975 TCP *.hamachi.cc
ip allow 32976 TCP *.hamachi.cc

for example would be what to implement.

The first port is used for an initial contact, and the second is used for an actual session.

If the methods above fail in connecting the the Mediation Server, Hamachi will try to use standard SSL connectivity (TCP port 443) to connect to it.

To troubleshoot, first try pinging one of the servers:

ping bibi.hamachi.cc

If this failed, then either your software firewall (on the machine), or a network firewall blocking traffic to our servers. You'll need to determine if it's your local machine, or something in your path to the server that is causing the issue.

tracert bibi.hamachi.cc

This will most likely tell you where the issue lies.

Keep in mind that if both the default connectivity, and SSL are failing, the most likely cause is either a network firewall/filter, or a proxy server misconfiguration (settings locally or the server itself).
