  1. Found this article in Help Net Security. Does this affect AirVPN in any way? --------- The team running the Perfect Privacy VPN service has discovered a serious vulnerability that affects all VPN providers that offer port forwarding, and which can be exploited to reveal the real IP address of users. Dubbed Port Fail, the flaw affects all VPN protocols (IPSec, OpenVPN, PPTP, etc.) and all operating systems. .... Source: http://www.net-security.org/secworld.php?id=19164
  2. I purchased a Netduma gaming router fairly recently and wanted to make use of its VPN feature which, to the best of my knowledge, is a Linux terminal. I tried ExpressVPN and after a valiant effort of support from their side we could not get it to work. Then i tried PureVPN (stupidly) and all requests for support were ignored in an effort to run down down my 72 hour money back period, I presume? I almost threw the towel in on the whole VPN thing until i read a review about AirVPN and their one Euro trial, if all I've got to lose is a Euro ill give it a crack, I thought. Signing up was a breeze, the config generator removes all confusion if, like me, you are not overly tech savvy with the script, it just provides plug & play code for your device and, most importantly, it just works!! Signed up for a years service and if you are a Netduma user and you are experiencing difficulty with your VPN provider you should definitely invest a Euro in giving these guys a try!! Thanks AirVPN!!
  3. Hi, I got yesterday a 3-day subscription to AirVPN for testing (before bying a longer subscription) but I can't make it work. The main symptom is the extremely low speeds. My PC (Windows 7 64bit Prof) is on a Gigabit line. My normal speeds, according to speedtest.net, are around 500-600mbps (down and up). With AirVPN connected, my speed usually gets lower than 10mbps! Sometimes I get good speeds (60-100mbps) but as soon as I start uTorrent, the connection stalls to the point even DNS resolving fails. Something I noticed: the TAP adapter always says "Unintedified network" and, according to ipconfig its "Default Gateway" is empty. Is that normal? I have tried both OpenVPN and the AirVPN app. in both cases the logs are clean (no errors or warnings) but the problem persists. Also I tried uninstalling everything relevant (even the TAP adapter) and reinstalling but nothing changed. I know my ISP is ok with OpenVPN. They use it for some of their services too. So, any ideas on how to resolve this mess? Or at least how to get some usable debbuging info? Thanks!
  4. i was able to use the client successfully but when I restarted my Windows netbook/tablet, I can fire up the AirVPN client but it gives me a message that says 'Open VPN not found.' This issue doesn't allow me to connect to any server. Any help would be appreciated. OS: Windows 10 32bit Asus One 10
  5. Hi, I am using AirVPN on a windows computer and have been having this problem for the past two days. It keeps re-connecting every few minutes - please see the attached log - AirVPN_log.txt. I am not sure what's causing this OpenVPN > [server] Inactivity timeout (--ping-restart), restarting It's been very frustrating two days and would appreciate anyone's help in resolving this. Thanks
  6. I've tried to connect to a bunch of US servers today and they all fail while trying to add the route info, but I can connect to any Canadian server. I've changed my protocol settings but nothing changes.
  7. Hello folks, I have setup my Netgear R6250 with DD-WRT, and OpenVPN connecting to AirVPN. This is all well and good, but now I'd like to somehow be able to choose which traffic is inside or outside the tunnel, either by source IP/subnet, port, destination host, or some other way. A GUI to accomplish this would be wonderful, but not essential. I am open to adding additional devices to perform such functions if that's necessary. I've read many (many many) myriad forum posts and wikis offering differing, conflicting ways to accomplish this using DNSMasq, iptables, Policy based routing, Source based routing, pfSense, and apple pie (I made one of these up). I think much of this is due to the various versions of dd-wrt available, the wonderful various options available to the power user to configure the way they want it, and that there's several different approaches that may or may not work on any given hardware. What that equals for me is confusion. Its my intention to set this up, and document the process in a way that's easy to follow, and add my own experiences to those already floating on the intertubes. Ideally I'd accomplish it with just some dd-wrt trickery. So far the solutions I've found have been written with a specific setup in mind that I'm unable to adapt to my setup, or they just didn't work (or I didn't understand them). It'd be great if we can talk through it together, and rejoice together in our shared insight and accomplishment.
  8. I have been up and down old guides to set up my pi to run a seed box, but each source is a little confusing and has a few steps missing/different/outdated. Can anyone please link or type up a proper set up guide to get the Pi on Rasbian set up quickly and painlessly, along with how to auto boot the config with no leaks in plain English? A Linux built client for ARM processors could do wonders in this department. Thank you!
  9. My setup is this; Asus RT-N66U "Black knigth" running the shibby AIO version of TomatoUSB I've set up the 1st OpenVPN client (tun11) and am forcing all traffic from a specific (internal) IP though this connection. The above works really well so I wanted to setup up a wireless network were all clients that connects are added to a different subnet and all IPs in that subnet be forced through the 2nd OpenVPN client ( tun12 ). To this end I setup; - a new VLAN (br1) - a new Wireless SSID ( wl0.1 ) that is using that VLAN This works and clients can connect, get the correct IP and can access the net. I copied every setting from tun11 to tun12 I can connect the 2nd OpenVPN. When I start the scripts to force the subnet though the tunnel I get various DNS related errors in the client ( Android 5.1.1 with chrome browser ) unless I stick to refreshing an already loaded page, the page will show the correct vpn IP however ( simple php page with <?=$_SERVER['HTTP_X_FORWARDED_FOR'];?> ) It seems that somehow DNS isn't working for the 2nd connection, and I can't for the life of me figure out why. Trouble shooting I've done so far; Shutdown both VPNs and only start Client2 - no difference Routing br1 through Client1 works perfectly ( "ip rule add from lookup 200" ) So I'm starting to think that there is something wrong with my settings for Client2; The relevant settings ( minus the VPN ip's as they are irrelevant ) - what am I missing / where did I screw up? Client 1 Client 2 Script -> firewall ( custom addition to the firewall rules ) iptables -I FORWARD -i br0 -o tun11 -j ACCEPT iptables -I FORWARD -i tun11 -o br0 -j ACCEPT iptables -I INPUT -i tun11 -j REJECT iptables -t nat -A POSTROUTING -o tun11 -j MASQUERADE iptables -I FORWARD -i br1 -o tun12 -j ACCEPT iptables -I FORWARD -i tun12 -o br1 -j ACCEPT iptables -I INPUT -i tun12 -j REJECT iptables -t nat -A POSTROUTING -o tun12 -j MASQUERADE the up/down scripts that takes care of the routing root@unknown:/tmp/home/root# cat /jffs/vpn1_up.sh #!/bin/sh #iptables -D OUTPUT -s -j DROP ip route flush table 200 ip route flush cache ip rule add from lookup 200 VPN_GW=`ifconfig tun11 | awk '/inet addr/ {split ($2,A,":"); print A[2]}'` ip route add table 200 default via $VPN_GW dev tun11 root@unknown:/tmp/home/root# cat /jffs/vpn1_down.sh #!/bin/sh #below line doesn't work #iptables -A OUTPUT -s -j DROP ip rule del from lookup 200 ip route flush cache root@unknown:/tmp/home/root# cat /jffs/vpn2_up.sh #!/bin/sh ip route flush table 210 ip route flush cache ip rule add from lookup 210 VPN_GW2=`ifconfig tun12 | awk '/inet addr/ {split ($2,A,":"); print A[2]}'` ip route add table 210 default via $VPN_GW2 dev tun12 root@unknown:/tmp/home/root# cat /jffs/vpn2_down.sh #!/bin/sh ip rule del from lookup 210 ip route flush cache
  10. I've been having a very odd problem with AirVPN, and this issue seems to be present in both the AirVPN client as well as Viscosity (OpenVPN). I can connect just fine, with no issues at all. However, after a few minutes my donnection drastically slows and becomes non-responsive. In order to get my connection working again I'll need to restart because the adapter is unresposive as well. Here is some of the log file from the airvpn client. I eliminated repetative entries. ​ I am experiencing the same issue in both the stable and expieremental builds. As I said I am also having the same problem using OpenVPN; I can connect fine and in fact I get great speeds at first. Then my connection slows and eventually is non responsive. ​ ​ Any ideas? Could this be triggered by torrenting? Thanks. ​ ​
  11. I'm with Virgin Media in the UK, on 160/12 cable. Last year I had a spate of low speed (3MB/sec hard cap) which I initially blamed on throttling of OpenVPN as I could hit full speed on my naked ISP connection. After some investigation I found it was actually a bug in the ISP supplied router, so I switched to my own and the problem went away. Lately however, I'm having a hard speed cap problem and it really looks like issues caused by either VM's use of DPI and/or OpenVPN throttling/shaping at ISP level. VM operate a whitelist for shaping, so unless the protocol is whitelisted it's shaped by default. VM categorically and publicly deny any form of throttling, shaping or interference with OpenVPN connections. I've been using an Ubuntu torrent as a speed benchmark as it's multi-threaded, consistently very fast, and can be used off-VPN without fear of legal issues. I have tested every port and protocol in Eddie, as well as via Viscosity (to rule out Eddie issues). I also tried the same tests with several other well respected VPN providers with good networks and the results were consistent across them all, Air included. Note that I am using MB/sec in its proper format, meaning megabytes per second. 1MB/sec = 8Mbps. All results are for the same Ubuntu 15.04 x64 torrent downloaded in the latest qBittorrent v3.2.3 on Mac OS X (also verified on Linux, PCBSD and Windows 8.1 Pro). As well as checking against multiple VPN companies, multiple OpenVPN software and multiple operating systems, I also reproduced the results on multiple machines (mid 2012 MacBook Pro and my FX8350 / 16GB DDR3 / Samsung Evo 850 sad / Radeon R9 380 gfx desktop). I repeated the tests with several ethernet cables (to rule out cable issues), as well as with *machine* > router > modem and *machine* > modem (to rule out firmware or routing issues). Every time, regardless of the variable, the results below were consistent. ISP : 19MB/sec OpenVPN 53 UDP : 2MB/sec OpenVPN (all other ports in turn) UDP : 5MB/sec OpenVPN (all ports) TCP : 4 - 5 MB/sec OpenVPN + SSH 22 : 2MB/sec OpenVPN + SSH 80 (or 53) : 13 - 18 MB/sec (lower in peak times, high off-peak) OpenVPN + SSL 443 : 13 - 18 MB/sec (lower in peak times, high off-peak) As we can see, generally SSL and SSH masking the OpenVPN connection allows almost full line speed (minus the encryption overheads). That's great. As soon as it's a bare OpenVPN connection the speeds cap out at around 33% of what they should be. Bare OpenVPN TCP is a little slower than UDP (as you'd expect) but otherwise in accordance with the general 5MB/sec cap experienced on UDP. The only exceptions are UDP:53 and SSH:22 which are both heavily restricted to around 2MB/sec. Now to my mind, knowing what I do of VM's shaping and DPI systems, this would only make sense if they were interfering with OpenVPN either by purposefully throttling it, or else their DPI system is messing up the connection. They further seem to restrict SSH:22 and UDP:53 by protocol but not by port. This actually makes sense, as all other Eddie combinations are quite random whereas SSH:22 (SSH) and UDP:53 (DNS) are established network traffic protocols and thus could be singled out for listing in the shaping systems. If we reverse the protocol/port (to give SSH 53 and UDP 22) we once again obfuscate the tunnel and go back to full speeds! I also get a lot of decrypt/replay errors in the logs on every single port for 'normal' OpenVPN. As soon as I hide the OpenVPN in either SSL or SSH the errors simply don't occur. Ever. This suggests that the extra tunnel is hiding the OpenVPN tunnel from being shaped, or else the DPI process in and of itself is breaking OpenVPN and causing the packets to arrive out of order. Maybe that in and of itself can hurt speed? So there you go. Sorry for the long post but it's an interesting (if thoroughly frustrating and annoying) issue. What do you gurus think? Given I have worked to change the variables one at a time to rule out issues with AirVPN (different providers), the router and/or its firmware (direct connection to modem, bypassing router), wireless issues (used ethernet directly) and OS limits or bugs (used multiple OSs) I can't see anything is left... except issues with the ISP shaping/throttling or else their DPI breaking things. I posted a thread very similar to this in VM's support forums, but for a whole week it has gone unanswered by any staff. Interestingly it is the only thread on the forum to have been ignored. Make of that what you wish. I await your replies with interest. Thanks in advance for reading.
  12. Dear AirVpn Forum Members, Since i am using Airvpn in my work, behind work firewall, my firewall blocks ddwrt open vpn connection. But in my computer I can use AirVpn SSH in my work. All i need please make a tutorial, how we setup ssh + openvpn on to DDWRT routers for airvpn. There is SSH service in DDWRT. I need how we configure it. Could you please show me the configuration of SSH + airvpn openvpn settings for ddwrt router? Best regards,
  13. I've searched and tried everything and I can't get anything to work. Here's my setup. I have the Verizon Fios Actiontec router with a Asus RT-N16 as a secondary router with Tomato installed. The Asus is on a different subnet than the Actiontec and the Asus connects to AirVPN. I run everything through the second router which connects to AirVPN. I tried setting up forwarding the ports on AirVPN to have my Plex server visible through the VPN, but nothing. Most of the setups I see with Plex connect with the software client. Can someone point me in the right direction?
  14. Hello guys, I have a quick question which hopefully results with a quick fix. This is my first time trying to get VPN running on Arch. What I have done is download the congfig file, extracted into /etc/openvpn then through terminal typed in sudo openvpn --config /etc/openvpn/AirVPN/name_of_the_file_.ovpn The problem comes after the command executes and terminal outputs 'Sequence Authenticated'. I have no longer a connection nor can run a ping command. I am pretty sure I a missing a step. Any ideas? Please pardon my English and thank you much in advance.
  15. I m connected to Talitha and all DNS is going trough the VPN.

(tested on https://ipleak.net/) Can anyone explain this behaviour?
  16. Something I just read. Packet chaining, interrupt coalescing and other additional features like chimney offload are not supported by every interface or interface driver. It generally works with Realtek and Intel interfaces, though I experienced some exceptions in the past.. Would be interesting to know if these are available in the TAP driver...
  17. Hi to all. Little issue here. i want to cast a video through chromecast to my tv (with apps like crunchyroll or youtube), but when my android phone was air-connected (with openvpn) the chromecast results as "not found" on my network. if i turn off the vpn connection, chromecast return available. instead sending chrome tabs working normally with PC (windows 7). what can i do, any suggestions?
  18. Hello, I have installed and configured OpenVPN on OpenWRT and it works with the interface tun0 configured such that OpenVPN automatically starts on bootup of OpenWRT and if there is no VPN connection then the Lan-network cannot access the WAN, only OpenVPN when it is up and running. But I have a problem with Port Forwarding. I have "made" a forwarded port in the Client area of Airvpn. But when I have my program up and running using that port it is not accessable and also clicking on the "check" button from Aivpn of the port shows it is not accessible. Does anybody know and can help we with setting up a correct port forwarding in OpenWRT for the VPN? I have tried but nothing did succeed
  19. Hello, I just signed up for your AirVPN service today. I am using OpenVPN on Ubuntu to connect through AirVPN. I have everything setup as described on How-Tos section. The only thing is there is no Internet connection even though I am able to connect to AirVPN server. I did do the ping as follows... and it works. ping www.google.com or ping But when I open my firefox browser to a website, the browser just stils there spinning its wheel doing nothing.... I litterally waited for about 30 minutes. It never displayed any website that even includes Google.com.... I am shocked. Could someone please help me.... thank you.
  20. Hi, I am in the process of trying out AirVPN and cannot get internet access when using OpenVPN from my Linux Machine. It works with the AirVPN app fine, but I would like to use the OpenVPN method with generated configuration files. The OpenVPN method is needed because I want to run the VPN on a headless linux machine. I have tried a few different ovpn files with OpenVPN with limited success. Any help appreciated please?
  21. Hi, I guess my real IP is leaked. I am in the Netherlands and I want to use a German VPN. When I check my IP all seems fine. But all the ads and google+1 is in Dutch!? (See attached image.) ipleaks.net and dnsleaktest.com don't show that leak. I use OpenVPN and update-resolv-conf and I also added following line to the ovpn (for which I used the generator): script-security 2 up /etc/openvpn/update-resolv-conf down /etc/openvpn/update-resolv-conf I deleted all cookies, cache, and flashcookies. How does google for example know my real location?
  22. Hey! I've got an annoying problem since today. Whenever i make a connection with OpenVPN windows analyzes the network type and decides it's domain (since the machine is on a domain). Would not be much of a problem, but my killswitch is based on that the ovpn-connection is treated as "public" not domain. Now, whatever i try to do, it still becomes domain. System: - Win7x64 on 2012R2-Domain, latest openvpn, nothing else (yet). What i tried: - setting every unknown/new network as public via GPO - also doing the same via local secpol - setting ndistype for the tapi-interface of ovpn - deleting nlm-cache, deleting routes, resetting ip4 completly - setting network type via registry Starts to drive me mad :-) Would be thankful for any idea!
  23. Hello, Trying to connect from iPad to UK (area) proxy servers per instructions here https://airvpn.org/ios/ Connection not established, throws "Connection timeout", I've tried "Advanced Options", "Resolved hosts in .ovpn file" and "All servers for area or region" as per here https://airvpn.org/topic/10000-connection-timeout/ OpenVPN log attached (openvpn.txt). Any suggestions most appreciated. Thanks! Swain openvpn.txt
  24. Hi, I'm very new to all this kind of tech and wondered if anyone can help. I currently have a cloud ibox2+se satellite recieved box that has an option in it called openvpn and I just wondered if anyone can assist me in getting it to work with my virgin super hub router, I'm a bit nervous to mess around with any settings without any advice or tutorials. All help greatly recieved. Many thanks
  25. I'd like to share the configuration which I use with VPN in order discuss and for others to use. The idea is to launch apps which should use VPN inside a separate network namespace. Other apps will run inside the default network namespace and use the default direct connection without VPN. Linux network namespaces enable you to configure a container with separate set of network interfaces with separate routing table, separate firewall rules and separate resolv.conf. Only processes which are inside the namespace will be able to access and use all that. You should compile network namespace support in your kernel and the support the "veth" network device. veth is a pair of virtual devices. They operate this way: data that comes into one, comes out from another and vice versa. We use them to link namespaces together because your eth0 can only exist in one namespace. I am running: OS: Gentoo init system: systemd network managent tool: netctl (from Arch Linux, available in Gentoo) You would have to adapt your configuration if you're using anything else. It should be easy. GENERAL OVERVIEW. Default namespace contains these interface: lo lan0 veth1 br0 Additional namespace contains: lo veth0 tun0 lan0 is my physical net interface (you could think of that as eth0). Kernel links veth0 to veth1. br0 bridges lan0 and veth1 together. tun0 is the VPN tunnel through veth0. I called my additional namespace "vpn". This way processes from both namespaces can communicate with my LAN. Processes from the default namespace communicate this way: (br0) -> lan0. Processes from "vpn" namespace communicate this way. In case of a LAN connection: veth0 -> veth1 -> (br0) -> lan0 In general case: tun0 -> veth0 -> veth1 -> (br0) -> lan0 STEP 1. Startup script. Create a startup script which takes care of creating veth0/veth1 pair for you. It also creates the vpn namespace. In my case it is a systemd unit which runs before netctl: [unit] Description=Custom network namespace Before=netctl@bridge.service network.target Wants=network.target [service] Type=oneshot RemainAfterExit=1 ExecStart=/bin/ip netns add vpn ExecStart=/bin/ip link add type veth ExecStart=/bin/ip link set veth0 address 16:7c:e1:06:53:dd ExecStart=/bin/ip link set veth1 address f6:7c:e1:06:53:dd ExecStart=/bin/ip link set veth0 netns vpn ExecStart=/bin/ip link set veth1 up ExecStop=/bin/ip netns delete vpn [install] WantedBy=multi-user.target You can see that I am assigning MAC addresses here manually. The point is how br0 gets its MAC address. I want lan0's MAC higher than veth1's MAC in order for br0 to use lan0's MAC and for MAC-based DHCP server not to misbehave on my router. If br0 gets veth1's MAC, the machine will get a different IP address in comparison to what it gets without a bridge. STEP 2. resolv.conf After you run the script or reboot, you have to setup resolv.conf for the namespace. Look for it in /etc/netns/vpn/resolv.conf. For airvpn it should contain "nameserver" line. For a shell running in "vpn" namespace, /etc/netns/vpn/resolv.conf will be automatically bound to /etc/resolv.conf. STEP 3. Bridge interface. Setup the bridge interface. In my case it is a netctl profile in /etc/netctl/bridge: Description="bridge connection" Interface=br0 Connection=bridge BindsToInterfaces=(lan0 veth1) IP=dhcp TimeoutDHCP=15 STEP 4. Running openvpn in the namespace. Reboot and check that br0 is up. Create a helper script /usr/local/bin/ns_enter: #!/bin/bash ifconfig lo up ifconfig veth0 up ip route flush table main ip add flush dev veth0 ip add add dev veth0 ip route add default via metric 10 iptables -F OUTPUT iptables -A OUTPUT -d -j ACCEPT iptables -A OUTPUT -d -j ACCEPT iptables -A OUTPUT -o tun0 -j ACCEPT iptables -P OUTPUT DROP Note that you have to specify the IP address and gateway for your LAN. Now you enter the namespace this way: sudo ip netns exec vpn /usr/local/bin/ns_enter sudo ip netns exec vpn su - <your_username> is the VPN server. This rules allow all local traffic ( and all traffic through VPN. Note that you cannot put hostname instead of in your .ovpn file because openvpn wouldn't be able to resolve it. Check that the shell has access to exactly 2 interfaces: lo, veth0 (run ifconfig for that). Now launch openvpn: sudo openvpn --config /etc/openvpn/airvpn.ovpn --daemon You should see the 3rd interface (tun0) appear soon. Ready to roll. You can launch apps in background from the shell. The only serious problem I've encountered is that you can't runs apps which need dbus connections this way. I haven't figured out how to fix that yet. Setting the envitonment variable didn't help. Does anyone know why?
