Connecting BitName and wp.com to activate JetPack plugin

Hi;

I have searched on this without success. I also originally posted this question in the plugins forum, but it appears that was not the best place. Apologies.

I have started to create a wp dev site. I installed BitNami on my Mac, running Mavericks.

I installed a theme successfully. The theme needs JetPack. I downloaded and installed JetPack OK. But JetPack requires connecting to wordpress.com for activation. When I attempt that, wordpress.com sends this error:

Your website needs to be publicly accessible to use Jetpack: site_inaccessible

Error Details: The Jetpack server was unable to communicate with your site http://127.0.0.1:8080/wordpress [IXR -32300: transport error: http_request_failed Failed to connect to 127.0.0.1 port 8080: Connection refused]

What do I need to do to make my BitNami stack accessible to them?

Thanks
P.
