When installing openwisp2 via ansible-openwisp2, some users prefer to install on their local laptop for testing and playing with it.

However, one user went ahead and started using his local installation to try controlling real devices and noticed openwisp2 only listens on connections from localhost which makes it impossible to provide configurations to devices.

The fix is simply to correct the documentation in order to explain how to make openwisp2 listen on all interfaces, you can find the proposed solution at in issue #34.
