It's been complained about in the forum the instructions on setting up a DD-WRT router with airvpn located at https://airvpn.org/ddwrt/?hl=ddwrt is out of date. For the DD-WRT release I use, the guide is indeed a little outdated, but comprehensible. Still, without warranty and strictly on your own responsibility you could try my guide below. I am unable to provide any support, but this guide hopefully can help someone. For this guide I presume you know what a kill switch is, you know how to set up all other parts of your DD-WRT router such as setting up DHCP for example, and you know how to log into your dd-wrt web interface. In the client area of the airvpn web site, create config files, here. Select any server location and port, it doesn't need to be the one you will use, you only need the certificates & keys. Make sure to tick "Advanced Mode", and tick "Separate certs/keys from .ovpn file", then generate and download the configuration files. Log into your DD-WRT router and ... Step 1. Navigate to the "Services" tab then select the "VPN" tab. Step 2. Select "Enable" under OpenVPN Client. Step 3. Configure the first part of the screen as per screenshot below, noting comments below the screenshot. In the "Server IP/Name" field, indicated by a red arrow, you can either enter a specific server IP ( how to find a specific server IP )substitute the "XX" with the ISO code of the country you wish to connect to (for example DE for Germany, NL for the Netherlands, BE for Belgium, etc.)substitute the "XX" with the continent name (america, asia, earth, europe respectively)leave the field completely empty IF you wish to use random servers from a selection you specify. In this case, make sure to follow step 5.In the "IP Address" field, indicated by a green arrow, you should put the default IP of your router ("gateway"). How to find your router address is beyond this tutorial. Step 4. To configure the second part of the screen we'll need copy-paste from the config files you generated earlier. As per screenshot below, noting comments below the screenshot. Using your favorite text editor Open up "ta.key" and copy all of the contents into the "TLS Auth Key" field. (green arrow)Open up the file "ca.crt" and copy all of the contents into the "CA Cert" field. (blue arrow)Open up the file "user.crt" and copy only and including "----- BEGIN CERTIFICATE----- to the end of ----- END CERTIFICATE----- " into the "Public Client Cert" field. (brown arrow)Open up "user.key" and copy all of the contents into the "Private Client Key" field. (red arrow)Step 5. And the yellow arrow "Additional Config" field ? If in Step 3 you left the "Server IP/Name" field empty because you would like to connect to airvpn servers in a relatively random fashion based on a select preset of countries and/or continents and/or specific servers, this step 5 is for you. Copy-paste and amend: remote-random remote XX.vpn.airdns.org 443 (substitute XX with country or continent as explained earlier) remote XX.vpn.airdns.org 443 (substitute XX with country or continent as explained earlier) remote XX.vpn.airdns.org 443 (substitute XX with country or continent as explained earlier) ... remote XXX.XXX.XXX.XXX 443 (substitute with specific server IP) remote XXX.XXX.XXX.XXX 443 (substitute with specific server IP) remote XXX.XXX.XXX.XXX 443 (substitute with specific server IP) ... resolv-retry infinite As an example, it should look something like: remote-random remote AT.vpn.airdns.org 443 remote BE.vpn.airdns.org 443 remote BG.vpn.airdns.org 443 remote CA.vpn.airdns.org 443 remote asia.vpn.airdns.org 443 remote 185.156.174.114 443 remote 185.189.112.10 443 remote 91.214.169.68 443 resolv-retry infinite Step 6. Click "Save" at the bottom of the page then "Apply Settings". It should work, but a reboot never hurts. NOTE ON KILL SWITCH The Kill Switch in the original instructions may work for you. They did not work for me regardless of correct TUN. I used the below kill switch which I found to be working for me, so I share it here. Go to the "Administration" tab then select the "Commands" tab.Copy the following firewall rules into the command windowWAN_IF="$(ip route | awk '/^default/{print $NF}')" iptables -I FORWARD -i br0 -o $WAN_IF -m state --state NEW -j REJECT --reject-with icmp-host-prohibited iptables -I FORWARD -i br0 -p tcp -o $WAN_IF -m state --state NEW -j REJECT --reject-with tcp-reset Click on "Save Firewall" NOTE ON DNS It's been said in the forums (not finding reference to link, search refuses "DNS") it is better to use the airvpn server IP as DNS server. On a DD-WRT router, this is hard to achieve if you do not connect to a specific pre-defined server (most users). 10.4.0.1, one of airvpn DNS, is the next best IP to use as DNS server. However ... I found through trial and error - so this is only my pitiful experience - that if you do not put 10.4.0.1 as primary DNS, DD-WRT will keep using your primary DNS regardless whether connected to airvpn or not. 10.4.0.1 is not accessible outside the VPN, so you need a secondary VPN from another provider, such as opennic, find them here . You will find this leads to occasional DNS fallback, leaks if you will, to the secondary/other DNS when 10.4.0.1 is slow or disfunctional. But, such a DNS leak is still through the airvpn server IP, your location should still be hidden. So I would recommend in the DD-WRT control panel section "Setup" - "Basic Setup" - "Network Address Server Settings (DHCP)" to set the primary DNS as 10.4.0.1 and the secondary and further DNS as other free DNS servers, such as those from OpenNIC.

Hello forum! I've used OpenVPN on Asus RT-N18U running DD-WRT over a year now. I made files up.sh to start and dn.sh to stop OpenVPN to get rid of GUI and later on to run them via ssh from lan. OpenVPN version got updated to 2.4 and I made the necessary changes to conf file and scripts. It ran without issues couple of months. However, last Thursday my VPN connection went down while I was just browsing the interwebs. OpenVPN log was filled with messages: Recursive routing detected, drop tun packet to [AF_INET]62.102.148.132:443. There's no difference if I set up OpenVPN via GUI or use only my scripts. I've tried both UDP and TCP protocols but the issue persists. Outcome is always the same. Since then I've contacted AirVPN support as I cannot fix this by myself. I don't have the skills for that and I've tried my everything. As you may notice I feel desperate. EDIT: Here was a zip-file including kernel and ip routing tables, scripts, openvpn.conf file and OpenVPN log. I've censored my IP-address and tun1 IP from the files. All I found out is that the router for some reason removes line 62.102.148.132 via 84.xx.xx.xx dev vlan2 from routing table. You can see the difference between before-error_ip-route.txt. and after-error_ip-route.txt. DD-WRT seems to think that the fastest route outside is only via tun1 as VPN endpoint IP is in the same location as tun1 IP-address. Just a guess, might be totally wrong. Then it removes the previously mentioned routing rule and creates a loop. If I use allow-recursive-routing option in OpenVPN configuration, after a while log begins to spam "UDP messages too big" or something like that. I hadn't done any changes to DD-WRT settings, configuration files or script files. Recursive routing just popped up from no where. Router is being used as a gateway and WiFi AP only. All I've done is I moved to a new apartment which has different IP-address provided by the same ISP. That might not affect anything, just FYI. I really hope someone could help me with this. Thanks. Update: Turns out my ISP assings new IP-address every 20 minutes and almost every service on DD-WRT restarts which makes everything kind of frustrating to config...

Hi, I wrote a short review about different VPN services and how they are working on DD-WRT routers. AirVPN is also included as a part of the test. Was just testing against Swedish servers, since I'm located in Sweden want the fastest speed and lowest ping, even when using a VPN. Hope AirVPN is soon replacing all Kustband servers in Sweden, with only Altushost as ISP or similar providers

Hi AirVPN users! The latest OpenVPN for DD-WRT can be found here ftp://ftp.dd-wrt.com/betas/2020 but please choice builds higher then 06-01-2017-r32170 as lower builds dont have the vulnerabilities patch https://ostif.org/the-openvpn-2-4-0-audit-by-ostif-and-quarkslab-results

I want to use airvpn on my R7000. Currently, I can add single airvpn server to my router. I want to be able to switch to other airvpn server without reconfigure my router. Is there any possible chance to do it?

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,

A friend of mine is sending me a fairly beefy router which supports the latest builds for all versions of DD-WRT. While I wait, I was reading up on this page, and found myself curious as to whether stunnel is built-in as well, or if there is any way to do SSL tunneling for OpenVPN as in the AirVPN client?

I've spent the last hour trying to find out why I don't have any problem connecting to AirVPN but still have a red "Not connected" warning on all pages. Turns out that I had a privoxy adblock proxy installed and actively used on my computer. So while the vpn connection worked well it wasn't actually used because all traffic was routed through the proxy and not through the tunnel. Hope this helps someone because the forums and the internet didn't solve this problem.

I am trying to configure AirVPN as per the website instruction. I am running a Netgear R7000 with DD-WRT firmware (DD-WRT v24-sp2 (04/16/14) kongac). I have loaded the settings as pictured, but there are a few additional settings that aren't mentioned in the guide. At any rate, the status page never updates and I do not connect. Settings screenshot attached. Thanks. DD-WRT AirVPN Settings.tiff

Hello all, I am trying to find a way to make my home server (https, ftp, ...) accessible through the internet, while being connected to AirVPN. The OpenVPN client on my DD-WRT router is properly configured and connects fine. All the computers behind the router are available to browse the web and show the correct AirVPN IP adress. The server stays accessible from inside the private network . My problem is that I can't seem to find a way to make the server accessible from the internet, through my AirVPN WAN IP. For example, I have created a port forward on the AirVPN site from port 14645 to 443. My router is set to forward port 443 to the server's private IP, but this configuration doesn't work... Can somebody tell me how to properly setup port forwarding so that I can access my server through my AirVPN public IP ?
