EDIT 20:04 CET+1 06-May-13 Problem solved Hello! We regret to inform you that we are currently experiencing DNS problems on the following servers in the Netherlands: Ophiuchi LeporisLyncisOrionisCastorCorviThe problem affects DNS resolution. You might be unable to resolve some (and only some) names with our internal DNS (10.4.0.1, 10.5.0.1, ... , 10.9.0.1). The problem is external: it is not caused by our DNS or configuration. We're anyway working to solve it as soon as possible. In the meantime, as a momentary work-around (not compromising security): on Linux, OpenBSD and FreeBSD, just set a public DNS on your nameservers list after the connection. Example: in /etc/resolv.conf add the line "nameserver "on Windows, on your TAP-Win32 network interface (NOT on your physical network card) after the connection set preferred and alternate DNS IP addressalternatively, simply connect to any of our servers not included in the above list We will update this post as soon as the problem is solved. We apologize for the inconvenience not caused by us. Kind regards

Hello! Problem confirmed. We're posting an announcement and we'll be working to fix the issue. Kind regards

Hello! We amend our previous post, the problem can arise also on symmetric lines. It has been under discussion since two years ago: https://github.com/bitcoin/bitcoin/issues/273 As you can see there's no easy agreement on the issue. Kind regards

Hello! Currently it's not possible with the Air client. To achieve your purpose you can run OpenVPN as a service. Since our system provides a double-certificates / key authentication, no human interaction is required to connect at boot. Kind regards

Hello! We can confirm that (since we accept Bitcoin payments, we know the system): on ADSLs the Bitcoin client can sometimes saturate the upload bandwidth, "choking" the download bandwidth as well as a consequence. Kind regards

Hello! Some clarifications: AirVPN is based on free and open source OpenVPN by James Yonan and OpenVPN Project / OpenVPN Technologies, Inc.. We consider OpenVPN the most reliable and secure VPN client/server solution currently existing. OpenVPN is available for most existing OS (Linux, OS X, OpenBSD, FreeBSD, Android, iOS - in client mode, Tomato, DD-WRT, Windows...). OpenVPN can be invoked directly via command line or can be controlled through a wrapper or GUI. We don't bind our users and customers to run any proprietary software from us: the Configuration Generator can generate all the files needed by OpenVPN or any well-developed OpenVPN wrapper. Some wrappers have minor or major limitations, for example network-manager does not pass the explicit-exit-notify directive, Tunnelblick (an open source wrapper for OS X) is incapable to handle properly the socks-proxy and http-proxy directives. On Windows, OpenVPN is packaged with "OpenVPN GUI", an OpenVPN GUI. If you don't wish to run our client or OpenVPN directly, OpenVPN GUI may provide an excellent solution (as long as you don't need more than 50 configurations at once, currently OpenVPN GUI limit) and does not suffer, as far as we know, of any limitation apart the aforementioned one. The correct link Shippy was probably meaning is http://openvpn.net/index.php/download/community-downloads.html Kind regards

Hello! In the new system, the configuration generator is accessible in menu "Client Area". Click on "Client Area" on the upper menu, then click on "Config generator" in the left tabs. Direct link (while you're logged in): https://airvpn.org/generator Old previous post has been edited to reflect the changes in the new system, we apologize for the inconvenience.This thread was outdated (it refers to the new configuration generator of Aug 2012, since then it changed again). Now the thread and the links are on-sync. Kind regards

Hello! Difficult to say, in order to rule out or confirm that the switch is the "weak chain ring", would you be able to connect the XP machine directly to the router, just momentarily for a comparison test? Kind regards

Hello! The TAP-Win32 adapter for Windows is not limited to 10 Mbit/s. 10 Mbit/s is a bogus hard-coded value, it means nothing. Kind regards

Hello! That adapter is the virtual network card (the tun/tap interface) used by OpenVPN and it is strictly necessary. The 10 Mbit/s limit you see is just a bogus hard-coded value which has no significance at all. Kind regards AirVPN Support Team

Hello! AirVPN is based on OpenVPN. The configuration of each Air VPN server is the same and you can't change encryption algorithms, if you do you will not be able to connect to any of our servers. OpenVPN encrypts both Control Channel and Data Channel. In our servers Packet Authentication is also mandatory. Encryption algorithms are respectively RSA (with 2048 bit keys), AES-256-CBC (symmetric, 256 bit keys) and HMAC SHA1 (160 bit key). Authentication method is based on double certificates and key. TLS re-keying is performed by default every 60 minutes, with overlapping windows, so that the re-keying does not affect in any way performance and does not introduce any time-pressure. This is a parameter you can change on the client side, if you wish. If you're interested in going deeper, you can read an OpenVPN manual, or for a more synthetic summary the Wikipedia article. Kind regards

Hello! Choices of non-working ciphers in the configuration generator are not possible. It will generate files consistent with our OpenVPN servers settings. It would be detrimental (and somehow grotesque) that you could generate non-working configurations with the configuration generator... its purpose is exactly to generate working configurations for Air servers. Kind regards

Hello! Your OpenVPN client must match the cipher set in our OpenVPN servers. Our configuration generator will generate the correct configuration files. Current set: RSA 2048 bit keys AES-256-CBC Data Channel HMAC SHA-1 160 Packets Authentication Kind regards

Hello! Please use our configuration generator (menu "Client Area", then click "Config generator" on the left tabs), download and decompress the archive and put the downloaded files in the OpenVPN configuration directory. Launch OpenVPN GUI with administrator privileges (right-click and select "Run as administrator"). Right-click on the OpenVPN GUI dock icon (two small monitors) and select your favorite connection. If there are issues with OpenVPN GUI as well, please send us the OpenVPN logs (right-click on the OpenVPN GUI icon and select "Logs"). Kind regards

@caranda Hello! Same as above, you're running a Tunnelblick version which is incompatible with your system. Kind regards

Hello! Yes, no problems at all, total compatibility. Kind regards

Hello! Can you please try OpenVPN GUI? Kind regards

Hello! Can you please try to run OpenVPN GUI? This will help us determine whether the problem is in the Air client or not. Kind regards

Hello! The problem is here: Tunneblick 3.2.8 is not compatible with OS X 10.8.x. Please upgrade to an appropriate version, BUT please read here as well: https://airvpn.org/topic/9269-tunnelblick-33beta44-openvpn-221-critical-issue/ The reported problem might affect beta46 as well, if it's the case please apply the suggested solution. Tunnelblick can be downloaded here: http://code.google.com/p/tunnelblick/wiki/DownloadsEntry?tm=2 Kind regards AirVPN Support Team

Hello! We're investigating, please hold on. We can confirm at the moment port forwarding problems on Tauri. We will keep you updated. Kind regards

Hello! There are a search function and an advanced search function on the upper right corner of the web site forum pages. Please use them at will. In the EU we have servers in countries where Data Retention Directive (2006/24/EC) implementation has been declared unconstitutional (Romania, Germany) or where its scope does not cover our service (any other Member State). We fully comply to the EU legal framework. USA situation (under this point of view) is even better: in the USA currently there's no mandatory data retention at all, not even for domestic ISPs. Singapore, where we maintain 3 servers, has no mandatory data retention for our service. Please search the forum for references and documentation on all of the above. In order to look at Air VPN available servers please click on "Status" in the upper menu, you will access the servers monitor which reports many information. Yes, we have considered ways to counter-react in case of necessity. Kind regards

Hello! Please uninstall OpenVPN completely and re-install it. Make sure to authorize the installation of any driver. Kind regards

Hello! That does not depend on us. If you feel that it depends on us, can you please elaborate your considerations? Kind regards

Hello! In order to do so just click on "Copy to clipboard" and paste where appropriate. The logs do not show any problem. You might like to try OpenVPN over SSH to make a performance comparison which would tell whether your ISP throttles OpenVPN more or less than SSH. Kind regards

Hello! The problem has been fixed and the payment page is displayed again in English. Kind regards
