Implement OpenVPN test
Test that OpenVPN is working properly.
The test must:
- Establish a connection to an OpenVPN server.
- Check that the connection is successful or if it fails to connect to the server.
- Check that is possible to make an HTTP to a web server listening on the VPN network.
Open questions are:
- Which could be the possible failures connection to an OpenVPN server?
- What debug information can we get that would allow us to understand why and how OpenVPN is being blocked ?
