Contrarily to most VPN providers, we guarantee a minimum allocated bandwidth for each customer and we provide a real time monitor of the servers to check the available bandwidth on each of them. The speed you reach with BitTorrent is ok (12.5 Mbit/s you reported on the previous message), while speed with other protocols seems too low. Anyway the speedtest you reported on your first message with speedtest looks fine. First of all, to wipe out any doubt about torrent client leaks, please perform the test available at http://checkmytorrentip.com/ while you are connected to one of our servers. You can see the IP you are visible on the Internet looking at the central bottom box of our webpages. Check carefully that there's no IP leak: during the test, the site and the tracker must never see your real IP address, instead they must report the exit-IP address of the VPN server you're connected to (the IP address you see in our webpages after the connection is established). The test will take you just a couple of minutes. We're looking forward to hearing from you. Kind regards

We'll also add in the FAQ your suggestion for uTorrent which can improve performance. Technically, we don't do masquerading (in the meaning of MASQUERADE in iptables), but DNAT and SNAT (which is a form of masquerading according to some older definitions; in some literature, dynamic NAT is also called masquerading). Thank you for your cooperation! Kind regards

The problem lied in the source of the UDP packets when we added the exit-IP and entry-IP rules. They came from the entry-IP instead of the exit-IP, causing the answer packets by eMule to be routed outside the tunnel and be dropped. For all the details, see this tasty thread: https://airvpn.org/index.php?option=com_kunena&Itemid=55&func=view&catid=3&id=1276 Kind regards
  4. thigger wrote: Hello! Problem detected and fixed on all servers. Now you'll see incoming packets from the exit-IP, not the entry-IP. In this way the UDP reply will be routed inside the tunnel (if the reply was routed to the entry-IP, it would go unencrypted outside the tunnel to the entry-IP, and then dropped by the VPN servers - this was the cause of the problem). We apologize for the inconvenience. Of course, you will still be able to see real IP sources and destinations by capturing packets on the tun interface. Thank you for your cooperation and let us know if everything's fine now! Kind regards
  5. thigger wrote: That's the case with all VPN connections - but what I was wondering about is the specific feature of AirVPN where incoming packets on the tun0 interface (not the underlying eth0 interface) are masqueraded to appear to be coming from the vpn entry ip as mentioned above: I've had a look into it, and it appeared my torrent client was rejecting incoming tcp connections because they had the same ip address as previous ones (and not getting any udp ones, but that's in my previous post). The solution for uTorrent was to enable 'bt.allow_same_ip' in the advanced preferences; then you can see multiple incoming connections - all appearing to have the ip of the vpn server's entry point. Hello again! That does not appear normal at all. uTorrent should be working swiftly with bt.allow_same_ip set to "false". On the other hand, a web server could not work if the encrypted packets header were overwritten with the VPN server address, because the webserver would not know to which IP address to answer (while your web server behind AirVPN works fine even on Sirius, right?). Is it possible that your uTorrent tries to listen to your ethernet or wireless adapter, trying to bypass the tun interface on the incoming connections? Can you please do packet capture on your TUN/TAP interface to verify whether the packets come from the correct IP address (you should see packets coming from addressess different of the VPN IP addresses). Kind regards

    epoair wrote: Hello! No, Bittorrent clients are not able to bypass the TUN/TAP interface with their default configuration. uTorrent might try to do that with various systems (which can be disabled, like uTP), but all our tests have showed that it does not succeed. In a non-throttled, ideal environment, and on big swarms rich of seeds, you should normally have better performance with p2p than any other protocol. Better performance and higher efficiency are of course among the strongest features of BitTorrent. Anyway, for additional security, please perform a check on this website: http://checkmytorrentip.com/ You should carefully check that your real IP address is never leaked during the test. We're looking forward to hearing from you. Kind regards
  8. thigger wrote: Hello! Thank you for the warning. Remote forwarding is enabled both for TCP and UDP ports. You should be able to see that TCP packets for your web server have the correct header when they reach it (confirmed by the correct web server answers). We'll anyway look into this. Which server are you connected to? Can you please elaborate about UDP packets? UDP is a connectionless protocol, and http and https are not expected to be run over UDP, so why should your web server receive UDP packets? We're looking forward to hearing from you. Kind regards
  9. thigger wrote: Hello! Sorry, this question remained unanswered in the previous message. Torrent clients and any other listening service are not getting multiple connections from the same IP address, they see the real origin IP address. When you see packets coming from one of our VPN servers, the "original" header is encrypted together with the payload (otherwise your ISP could see the real origin with DPI). That's why you observe all packets coming from the entry-IP address of the VPN server you're connected to. The packets are decrypted by your OpenVPN before they arrive to the listening service. You can easily verify by monitoring the traffic on your TUN/TAP interface, instead of your Ethernet or wireless interface. An excellent tool to do that is Wireshark. Kind regards
  10. Hello! Yes, it's normal. You connect to a VPN server IP address (entry-IP) and you are visible on the Internet with another IP address (the exit-IP of the same server). It is not mandatory for OpenVPN (or any VPN in general) to have its clients connected to an IP address and get out with another (i.e entry-IP and exit-IP may be the same, as it happens in almost every VPN service), anyway this is an addition, completely transparent for clients, that we have made few months ago to enhance the anonymity layer (it makes correlation attacks harder and has the benefit to avoid out-of-the-tunnel unencrypted transmissions between two clients connected to the same server which communicate to each other). NAT and masquerading do all the job, so that your listening services (web server, torrent client...) are reachable from the outside (on the forwarded port(s)) and can respond properly to the incoming packets. When you receive an incoming TCP connection, you should see a packet directed to your TUN IP address (assigned by the VPN DHCP - see also https://airvpn.org/index.php?option=com_content&view=article&id=74&Itemid=141). Just a question, why do you say that you see connections coming from an address "similar to the entry-IP"? The incoming connections to your TUN interface should come from the entry-IP address. For example, on Lyra, you should see TCP IN of the type 62.x.x.85:-->10.x.x.x: (you can see your exit-IP just watching at the address reported in the bottom central box of our website while you are connected to a VPN server). Do not hesitate to contact us for any further information. Kind regards

  12. Hello! The logs look ok, perhaps there's too much lag between our german server and the TOR relay. Try changing server. Also, can you please test a connection over an external http-proxy? See this thread for details: https://airvpn.org/index.php?option=com_kunena&Itemid=55&func=view&catid=3&id=1256 Kind regards
  13. Hello! Yes, Air over TOR has been successfully tested repeatedly. Please make sure that you use a TCP port for connection to an AirVPN server (check the line "proto tcp" in the configuration file). Can you please send us the logs of failed connection attempts? Kind regards
  14. @Kitnick Ok, support from now on transferred to e-mail. You'll receive a reply soon. Kind regards [EDIT] Please note that the problem has been detected from your log files. Unfortunately you gave an invalid e-mail address, so we can't send you via e-mail the solution. We paste it here: The first part of the log shows an "AUTH_FAILED" problem (maybe the connection was too lagged, it may happen with an http proxy) which anyway is solved in the second connection attempt displayed on the log. The second part is significant because it shows a failure in the "route.exe add" Windows command. If the command fails, like it happened, your traffic can't be routed inside the encrypted tunnel (you can see the failure on all the lines reporting "route addition failed [...] accessis denied"). FlushIPNetTable failed as well for the same reason. Under Windows, this problem usually is caused by a lack of privileges for OpenVPN. Please make sure that you launch OpenVPN with administrator privileges (so that it can modify the route) and also that OpenVPN was properly installed (the installer must be launched with administrator privileges too). Finally, please check that the TUN/TAP adapter has been properly installed (Windows might complain about unsigned drivers). Kind regards
  15. @daicec Hello! You are not authorized to access the VPN servers. You need a premium subscription: https://airvpn.org/index.php?option=com_content&view=article&id=70&Itemid=132 We also accept Bitcoin: http://bitcoincodes.com/index.php?unit=store&op=browse&cat=10 and Liberty Reserve (please contact us for LR payments).

  16. @kitnick Hello! Attempt #3 failed because you specified a proxy which was not running (127.0.0.1:8118). Attemp #4 and #5 failed because of misplacement of user.crt, user.key and ca.crt files. When you put them in a different folder you have to specify the path on the corresponding .ovpn configuration file. Our configuration generator creates an .ovpn file which expects to find those files in the same directory you put the air.ovpn file itself. Attempt #6 failed because you specified a proxy which was not running (127.0.0.1:8080). Attempt #7 is ok. Our server sees you connecting from the http-proxy 78.133.146.136, while the proxy sees encrypted traffic from you directed to the VPN server, or coming from the VPN server and directed to you. You get out to the Internet with the VPN server exit-IP address. You can check this by browsing our website and watching at the address shown in the central box in the bottom part of the home page. Attempt #2 and #8 failed perhaps because of the http-proxy being down or too lagged. Now let's get a step back to see why Attempt #1 failed. Please try a connection only with the OpenVPN GUI (no TOR, no proxy) and please send us the complete logs. Please do not send an edited version, like the final part only. Then, try a connection with the AirVPN client alone (no proxy, no TOR, do not run OpenVPN GUI) and send again the logs (you can access the logs by right-clicking on the dock icon and selecting "Logs"; then you can copy them to the clipboard by clicking on the "Copy to clipboard" button in the middle of the bottom part of the logs window). We're looking forward to hearing from you. Kind regards
  17. Kitnick wrote: Hello! First of all, can you please try a direct connection to one of our servers, just to see if it goes through without TOR? If it fails, please send us the logs of the attempted connection. If you can connect directly, when you wish to connect over TOR please make sure that when you have the "proxy" option enabled, you connect to a TCP port (you can pick the connection port by selecting the "Modes" tab in the Air client main window). If the above fails too, can you please try to connect directly with the OpenVPN client in order to determine whether it's a problem related to the Air client in your system? Just generate the appropriate configuration in the website with menu "Member"->"Connect without our client". Make sure to compile the "proxy" option, download the air.zip file, copy all the files inside it and paste them into the OpenVPN configuration directory (on Win 7 C:\Program Files (x86)\OpenVPN\config in a default installation). After you have launched OperaTOR (or any equivalent setup for TOR), run OpenVPN GUI, right-click on the dock icon and select "air"-->"Connect". Finally, the following is a currently working http proxy to perform connection tests without TOR: IP address 78.133.146.136 port 8080 Just insert in the air.ovpn configuration file the following line to make tests (do not launch OperaTOR, this is just a connection of AirVPN over http-proxy): http-proxy 78.133.146.136 8080 and make sure that you have the line proto tcp in the configuration file. We're looking forward to hearing from you. Kind regards

  22. @gzz Hello! We are working on that. Packets arte properly forwarded to clients, but some Linux boxes (including Ubuntu and Debian distros) do not answer to those packets. Windows (any version), Mac OSX and Android do not have this problem. We will keep you posted. Kind regards AirVPN admins
  23. @slammin_bulu_whack Hello! Yes, your assumption is not purely hypothetical. It may happen to any VPN provider anywhere in the world, not only in the USA. Let's be clear, if the action is authorized by a judge under alleged, direct or indirect, violations of human rights (in particular human trafficking, child exploitation, export of monitoring technology) we will fully cooperate with the authorities. First of all, no account data are kept on the VPN servers, and anyway we encourage not to use identity disclosing information in your accounts with us. With a seized, offline server, forensic analysts work would be impaired. Much more effective would be real time wiretapping on the servers. This, potentially, might be done not only by legal agencies, but also by criminal organizations, although it might be difficult to cover their traces. For this reason, as we have said in the statement you cite, we strongly recommend to use AirVPN over TOR if you need to send critical information (for example, a whistleblower who sends something to a journalist), and to encrypt those information. In this way, even real time wiretapping would be ineffective to disclose both origin of the transmission and content information. Using AirVPN over TOR instead of TOR alone has a series of significant advantages, amongst which to solve the problem of malicious TOR relays (the traffic is still encrypted when passing through a TOR relay, and the TOR relay can't see the final destination IP of your communications). Also, AirVPN (thanks to OpenVPN) supports VPN over http-proxy. In this case, you have to use the TCP protocol and you will be able to establish an AirVPN over proxy connection. The proxy server will see your real IP but not the real destination, our servers will not see your real IP address. Furthermore, the packets payload will still be encrypted by OpenVPN when passing through the proxy node. Another scenario with physical access to the server is the possible correlation between account codes and IP address. Suppose that you connect via AirVPN over TOR to one of our servers to send critical data. Then, you connect with the same account to the same server but without TOR. At this point, it is possible to correlate your previous connection over TOR with this new one connection (same account code), disclosing therefore your real IP address to those who have physical access to the server and are wiretapping in real time. So, for critical transmissions, you should also take into consideration to use a specific account, aimed to be used only with AirVPN over TOR, even only one time for additional security, so that it would be impossible to make correlations between account codes and your real IP address, even with real time wiretapping. Trial free codes available on Twitter or sent by us via e-mail are perfect for this purpose (they have a maximum duration of 4 days). Just make sure that you use an e-mail account which can't be exploited to reveal your identity and perform the registration and the activation on our website via TOR. Please do not hesitate to contact us for any further information. Kind regards P.S. Vega is not with Leaseweb.
