AirVPN over TOR connection

[donald_duck 0]

Hi, I'm trying to use TOR and AirVPN together but I receive an error (I've downloaded TOR bundle and configured 127.0.0.1:9050 as socks in AirVPN connection). It fails to connect if I choose TCP or UDP for any possible port (443 or 80). The log is:

Hello!

Can you please make sure that you have selected a TCP port (the proxy can't handle UDP) and that the proxy type (http or socks) is correct?

Kind regards

[donald_duck 0]

Yes, I'm sure and I can confirm that to you.

[Staff 9972]

Yes, I'm sure and I can confirm that to you.

Hello!

Can you please try a connection over the TOR proxy directly with OpenVPN (i.e. not using the Air client)?

You can generate the appropriate configuration and get certificates and key with the configuration generator.

Kind regards

Can you provide a link with instructions? I'll make a test.

Thanks

I've created the script file for OpenVPN...

Can you provide a link with instructions? I'll make a test.

Thanks

Hello!

It's in menu "Member Area"-->"Access without our client", direct link:

Instructions for Windows are here:

Ok, thanks. It seems that I can connect properly, this is openvpn log:

Now, in Tor Browser if I check my IP I see: 173.*.*.69 and in the other browser (here I have not changed nothing) I see: 178.*.*.132.

It is correct? Which browser I have to use for full use of AirVPN and Tor?

Thanks.

Hello!

The logs are just fine and yes, what you see is exactly how it works.

When you use an application not configured to be tunneled over TOR, you will tunnel it over AirVPN over TOR transparently. On the Internet "you will be visible" with the exit-IP of the Air server the TOR exit-node sends to and receive from the packets.

When you use a program that is configured to be tunneled over TOR, you will tunnel it either over TOR alone (if it connects over the same proxy OpenVPN connects over as well, apparently your case) or over TOR over AirVPN over TOR (if you tunnel it over a different TOR proxy).

In all the above cases, your real IP address is never known to our servers.

So, to tunnel over Air over TOR, you need to use a browser NOT configured for TOR. In order to tunnel over TOR over Air over TOR, you need a browser configured to be tunneled over TOR which connects over a different TOR proxy. You can easily do that for example in a VM. In this way, when using the TOR browser in the VM, you will tunnel it over TOR over Air over TOR and you will be visible on the Internet with the Air server exit-IP address. In this case our servers will be able neither to see your real IP address, nor your "real" encapsulated packet headers nor your packets payload.

In general the second circuit of your TOR browser in the VM will be different from the first, established circuit "used" by your OpenVPN client.

Kind regards
