How and What to Post

If you are having a problem with Tunnelblick, please:

If possible, use the latest "beta" version of Tunnelblick, which has additional logging that can help show the cause of problems.

  1. Make sure you do not have manually set DNS server addresses in OS X System Preferences : Network (select the primary interface, click the "Advanced..." button, then the DNS tab; there should be no addresses on the left that are not dimmed).
  2. Open the "VPN Details" window.
  3. On the "Preferences" tab, please click the button to "Reset Disabled Warnings".
  4. On the "Configurations" tab, please select the configuration you want to connect in the list on the left.
  5. Make sure that "Set DNS/WINS" is set to "Set nameserver". This is the default setting and enables useful extra logging.
  6. Make sure that "VPN log level" is set to "OpenVPN level 3 - normal output". This is the default setting; higher levels are for debugging OpenVPN, which is almost never needed.
  7. Click the "Advanced" button on the right; a new window will appear.
  8. Make sure that "Check if the apparent public IP address changed after connecting" is checked.
  9. Close the "Advanced" window.
  10. Click on the "Log" tab.
  11. Click on the "Connect" button.
  12. Wait until the problem occurs. If the problem is that no connection is made, wait at least 70 seconds.
  13. If you can, click on the "Disconnect" button and wait until the disconnection is complete. If the disconnection is not complete within 20 seconds, continue anyway.
  14. Click on the "Copy Diagnostic Info to the Clipboard" button.
  15. Close Tunnelblick.
  16. Paste into an email or web form.
  17. Remove any sensitive information before sending the email or the form.
