Hi everybody,
I noticed how many people are struggling with installing and configuring OpenVPN. I struggled too the first times. In the truth, anytime there can be a misconfiguration if the process is done by hand.
That's why at some point I tried to use ansible to install OpenVPN. I use OpenVPN also in OpenWISP2, even though is not mandatory to control the devices, but at work
in our public wifi service still need VPNs to tunnel users to the captive portal, and in a few other
wireless community network initiatives we use OpenVPN to easily connect new nodes that cannot connect via wireless links.
If some of you will find this useful, I will suggest it in the openwisp website.
