Hello! PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets, so there are issues in making connections over OpenVPN over PPTP, or over PPTP over OpenVPN. The quickest way to achieve that is probably running PPTP in a host and OpenVPN in a guest OS (VM). Sorry, we don't understand, can you please elaborate? Of course we take every care and we do our utmost best NOT to have (hidden) open backdoors on our servers and we check constantly against vulnerabilities. Running only open source software helps that a lot. Kind regards

Hello! You should have found AirVPN (the client for Windows) and the OpenVPN installer. Air is based on free and open source OpenVPN, the most reliable and secure VPN client/server solution available. The Air client is an OpenVPN wrapper with some additional commodities for AirVPN. You need to install OpenVPN in your system in order to connect to AirVPN servers. Instructions for Windows: https://airvpn.org/windows OpenVPN GUI is a Graphical User Interface for OpenVPN. Kind regards

Hello! It's a feature disabled by default. It can be enabled for your commodity or help us troubleshoot problems. It records date, time, duration and bytes exchanged for each user session. It is not possible to enable IP logging or any other logging. It tells the system to display or not your login name in the servers monitor top data (on the right of the page), only for active sessions. It is disabled by default. https://airvpn.org/status Kind regards

Hello! Can you please check that the .NET framework 2.0 is installed in your system? Is there any additional detail in the error message? Kind regards

Hello! Can you please tell us the OS you run? Kind regards

Hello! It seems correct, the account is not subscribed to any plan. You should have received the message (on the account details panel) "Premium subscription required" if you tried a connection to a VPN server. If you feel this is a mistake, please do not hesitate to send us (in private) your invoice ID (or alternatively your transaction ID or reference) pertaining to your payment. Kind regards

Hello! We're glad to know that the problem is solved and thank you for your subscription renewal! Several months ago we added the message "Premium subscription required" in the account panel for such cases, as well as several messages that can help troubleshooting. The website account details page is important because we can't send messages to generic OpenVPN wrappers, so we would recommend to check it in case of any issue (besides, of course, writing to the support team). Kind regards

Hello! We don't keep logs so we can't give away information that we do not have. We can only say that until now no Air customer identity has ever been disclosed. Kind regards

Hello! Apparently the problem is solved, your account is currently connected to some server. Please do not hesitate to contact us if you have any further issue. Kind regards

Hello! Excellent, you don't need to do anything else. In order to try to have a more stable connection you might try connections to TCP ports, at the price of a performance hit. Normally there are no problems with UDP OpenVPN connections (see our servers monitor to verify how long clients remain connected) but if you have packet loss or latency issue intermittently, a TCP connection may help. Kind regards AirVPN Support Team

Hello! Thank you for your subscription! You can post Comodo global rules and network zones screenshots here or through the "Contact us" form or send us via mail to info@airvpn.org, as you prefer. Please download the following client versions. For 64 bit systems: https://airvpn.org/repository/air_windows8_x86_64.zip For 32 bit systems: https://airvpn.org/repository/air_windows8_i686.zip The client is compiled for .NET framework 4. We'll soon rationalize the Air client and OpenVPN packages now that OpenVPN 2.3 stable version has been released. Kind regards AirVPN Support Team

Hello! When you connect to a server and you have 30-40 minutes available to remain connected, please warn us and we'll check the port forwarding to your account IP directly from the server in real time. Kind regards

Hello! Can you please make sure that the proxy set in the Air client is the correct type and that the port protocol is set to TCP? Kind regards

Hello! We thought that "Reserved for AirVPN staff" was clear enough, but if it's not we'll be glad to modify it. The servers showed in the servers monitor page and in the configuration generator are the available servers for connections. If a server has problems you will see on that page an error status inside the server box. If a server is not shown there, it is not available anymore. If a server is withdrawn for ever or if its problems persist we publish an announcement on the forum. Finally, if all frontends are unavailable for forum access (emergency cases which should never happen, for example all frontends or all backends are down) we make announcements on Twitter. Theoretically, if a server goes down it should never happen that we are not aware of it, because our monitoring system sends the support team (via mail, IM and SMS) warnings and reports every 5 minutes. However it may take several minutes to understand the nature of the problem. Kind regards

Hello! We are reluctant to post the list here, please ask it through the "Contact us" form (or see the IP addresses with the configuration generator), we'll send it to you. Kind regards

Hello! Yes, we have noted recurring problems with Vega and Octantis in the past days. They are related to the provider's infrastructure: lines go down and the server get isolated from the world for several minutes or even hours, like today. If the problem will not be solved soon, we'll seriously consider to dismiss Vega and Octantis. Now Vega and Octantis are up and running. Just like with any service in the world, failures happen beyond the human ability to control reality. Anyway we notify about problems both in the real time servers monitor (with appropriate messages), the forum and Twitter in case of major problems. Kind regards

Hello! Which failure are you referring to? The german servers were and are up and running, please feel free to send us your connection logs if you need support. You can always see the infrastructure status here: https://airvpn.org/status Currently, at the time of this writing, the only unavailable server is Ophiuchi in the Netherlands, due to causes we're investigating (the server does not respond and does not come up after a forced power off/on). Kind regards

Hello! Well, that's unrelated (none of the above sends and receive packets to and from outbound UDP ports, for example). Anyway it was just a consideration to check, because we know many providers that perform port shaping always. Kind regards

Hello! The first check to perform is whether you use some third-party "network manager" bundled with Windows by the computer vendor (just in case you have an OS pre-installed by the vendor). An Asus network manager, for example (which handles both WiFi and Ethernet), has been reported several times by Air customers to slow down incredibly the throughput on the tun interface. De-activating it solved the problem. After that, we would recommend to check the logs to verify whether there's packet loss/fragmentation. In case of doubts just send us all the OpenVPN logs of one of your connections, in particular the slowest ones. In that case, it will be not easy to solve the problem, but there are some steps to try that could mitigate it. Finally, it remains to be seen whether your ISP deliberately caps bandwidth/deprioritize packets on some ports or with encrypted connections. In the European Union ISPs are obliged by law to declare such limitations (and any other limitation on applications, services and protocols) in the contract in a clear, understandable and easily accessible way, just in case you live in the EU. Kind regards

Hello! Excellent, we're very glad to know it! Windows firewall is dropping or rejecting uTorrent incoming packets on the VPN adapter (and possibly other programs as well). You should add uTorrent as a authorized/trusted application in Windows firewall on all networks. Actually Windows firewall may authorize a program on some network while keeping it blocked on a different one. Perhaps you might also consider to change firewall. Kind regards

Hello! We have performed various tests. The port forwarding in the server you're currently connected to works fine. The packets are forwarded to your VPN IP address correctly, but your system does not respond. Might there be anything on your system which is blocking incoming packets on the tun adapter? You can test with Wireshark or with the Comodo network monitor to verify that. A hint can be also given by uTorrent. uTorrent is able to punch our NAT, therefore it would not even need remote port forwarding. If you let uTorrent work without port forwarding (but with NAT-PMP and UPnP re-enabled) and share something, do you get a green token after a couple of minutes or not? Kind regards

Hello! If you can, please stay connected to the server you're currently connected to for some minutes, we'll perform some tests right now. Kind regards

Hello! Which firewall are you running? Do you get the same results also with the firewall off? Do you get the very same performance on all servers, all ports and all protocols? What happens if you connect to port 53 UDP and port 80 TCP? Kind regards

Hello! Can you please make sure that the service you want to be reachable is listening to the same port and that it is running while the port check is performed? Which service is it? You can try different ports and protocols, just in case your ISP performs port shaping. Try connections to port 53 UDP and 80 TCP to make a performance comparison. Also try different servers, even those geographically further to your location. Kind regards

Hello! Difficult to say for sure, anyway the symptoms point to a peering issue. Or maybe a routing problem. The servers are in the best Singapore datacenter, connected directly to tier1 providers. You might like also to check with your provider whether there are known issues of this sort with the http proxy. Kind regards
