I tried to tunnel two VPN's using my VM. AirVPN was running on W7 (Host OS). I launched Ubuntu on VM and then launched A/I VPN. I then checked my IP on Ubuntu, but it was still the AirVPN one. Plus the connection worked just for a few moments, then first A/I VPN dropped and after a second also Air dropped. Has this happened because both VPN's are using OpenVPN? It's just a wild guess, I am not experienced on this. Any suggestion? Thanks.
No, it's not that they're both using OpenVPN. Are they using the same tunnel networks? That messes things up. It could also be using the wrong DNS servers. Look for errors in the connection logs. And increase verbosity with "V 5".
Actually AirVPN Logs do not show any error, but I guess the Client store logs of the current session only. Since it had disconnected, errors might be lost in the previous session.. What do you mean about verbosity V5? Thnks.
That was a typo. I meant "verb 5". You need to edit your OpenVPN configuration file (*.conf or *.ovpn). There's probably a line with "verb 3" or whatever. Just change that to "verb 5". You'll get more detailed messages in the connection log.
