OpenVPN with Adguard

Jenova

Hi, I looked all throughout the forum for a way to use AdGuard with OpenVPN and I am a noob so I dont understand what IP im supposed to use? Is it the one i installed Cloudron on? A different one?

I got the settings button to show up on OpenVPN but when i put in the the server ip that both OpenVPN and Adguard are hosted on, i cannot connect to anything.

What am i doing wrong?

Thanks.

Hi, welcome here ! Can you clarify what IP you are talking about? I am guessing you have some specific UI/view in mind when writing this question but it's not clear which one. Can you maybe post a screenshot?

My IP of my VPS. I am using both OpenVPN and AdGuard on one VPS, one IP.

Basically, I want to be able to have a VPN with AdGuard but the documentation is confusing.

No idea where to start with screenshots or where we should begin with this.

I know i need to edit Open VPN to be able to see the Settings button on the Admin page but when I put the same IP address its hosted on (Since AdGuard is hosted there) i fail to connect. I could see why this would happen as its looping into itself but not sure if i should post the IP address here, for security sake?

Thanks for looking into this and apologies if this is confusing, its confusing to me too. Lol.

Have you seen https://docs.cloudron.io/apps/openvpn/#custom-dns-server ? Or are you saying that is the doc which is confusing?

Jenova

@girish the documentation is confusing. It's asking for the IP of Adguard but it's the same ip as what
OpenVPN is currently hosted on. At least I would assume so.

girish

@Jenova ah ok, I can clarify the docs further, after we discuss it here.

The situation is:

If you just install OpenVPN app, there is a built-in dns server. This built-in DNS server lets devices identify other devices on the VPN.
There is an option to set some other DNS server. This DNS server can be Google's DNS, Cloudflare's DNS, Pi-Hole, AdGuard DNS server etc. Now, it just happens that we have an AdGuard Home app on Cloudron. If that is what you want to use, you would use the IP address of the app (i.e same as the public IP of the server).

I guess the confusion is that you think AdGuard is somehow built into the OpenVPN app? They are totally separate things.

Jenova

@girish no. I know it's not. I just figured since I had OpenVPN and Adguard on the same server it was what caused it not to connect. I figured it was going in a loop between Adguard and OpenVPN since it was on the same server. I'll try adding it again and seeing what it does but iirc, it dosnt connect.

girish

@Jenova tried this now.

Installed both apps.
Put the DNS in settings.
Connected on VPN.
Did a random DNS query.

  $ host does-this-site-exist.com
Host does-this-site-exist.com not found: 3(NXDOMAIN)

I see it in AdGuard.

Jenova

@girish ok. I just did this and my computer cannot connect to any site.

To add, I see the DNS being set nicely via systemd-resolve --status

Jenova

@girish do you think I need to reinstall both?

girish

@Jenova which OS/client are you using ? I think it's probably some networking related issue we have to debug step by step.

Are you able to ping by IP address? Can you ping Cloudron server by IP ?
Then, host cloudron.io adguard-ip-address . Does this work ?
Then, we have to figure if the openvpn client configured the OS with the right DNS server.

To test a couple of more things:

Can you try with setting the DNS server as 8.8.8.8 (this is the Google DNS). Does that work?

Jenova

I'm confused. Do you want me to run that host command in my server? Is adguard-ip-address what I should put or should I put the ip address of my server?

Ping? How do I do that?

Where am I putting the Google DNS? In my OpenVPN Settings page?

Sorry, I have literally no idea what I'm doing here and I'm actually kinda frustrated.

Ok, so to update, i put the Google DNS inside of OpenVPN's settings and still no connection was being made

@Jenova Let's take a step back, I feel I made too many assumptions here.

Without any of this DNS stuff, does the OpenVPN app work for you with the defaults? I assumed it does, but I want to double check this. If it does work, can you tell me

a) where is your server hosted? Intranet or public cloud ? Anything special I need to know about the network?

b) which OS and vpn client are you connecting from ? This is important to debug further because all the commands I am giving you are for linux desktop.

I assume Intranet. Its a VPS with HostWorld. I have no idea if there is anything you need to know about the network.

The OS on my VPS is ubuntu-20.04-x86_64 and im using Windows 11 (Insider Edition, if that makes a difference).

girish

@Jenova thanks.

With the default OpenVPN app settings, please connect from Windows. After connecting, can you please check what it says the DNS server is? https://askleo.com/find-dns-server-used-pc/ says if you run ipconfig /all , it will display the DNS servers. Can you post what that command returns?

Also, I am not a Windows expert. TBH, I haven't even used Windows in many years, but I will try my best and let's see how far we get

So, the above line tells us that it got the internal DNS server correctly. So, far so good!

Next step: Disconnect from VPN. Then, go to the OpenVPN settings and put '8.8.8.8' as the DNS server. (https://docs.cloudron.io/apps/openvpn/#custom-dns-server) . Now, connect again.

Are you able to connect to VPN or is it that you are able to connect to VPN but unable to connect to any website? If you run ipconfig /all again now like before, what is the output ? (I am expecting the DNS Severs to be 8.8.8.8).

Ah nice, it does get the configuration correctly!

Its funny cuz now i can connect.

One thing to know is that these days browsers also have all sorts of DNS caching going on. So, best to restart browser to make sure we are testing things afresh.

Can you tell me what happened between being able to connect initially and not being able to later?

In the output where you can't connect, the DNS server is wrong 23.237.137.11 .

Also, out of curiosity, maybe you can also try to connect from your phone and see if you are able to connect. This will help identify if this is some openvpn client issue or some server side issue. I suspect something with Windows OpenVPN client.

I added the IP address of where my AdGuard is hosted.

23.237.137.11 is the ip of which both Adguard and OpenVPN are hosted at so i assumed it would be what i would put in OpenVPN's DNS.

I will try tho and report back

Edit: It works flawlessly on my phone.

@Jenova I guess that's good news and bad news

I have to leave you on your own here, since I have no clue how Windows DNS works. See http://woshub.com/dns-resolution-via-vpn-not-working-windows/ and https://serverfault.com/questions/356115/vpn-connection-causes-dns-to-use-wrong-dns-server for maybe some ideas.

Unfortunate but I'll ask on Adguard and OpenVPN forums then. Thanks for your time.

@Jenova it happen to me when I didn't add my secondary Server IP(Adguard) on primary vpn server with cloudron.

So I went to my adguard server and I had go to setting on webgui->setting->dns-> allow client so I added primary IP on there and now it working.

I don't have a secondary IP. The VPS with which OpenVPN is hosted on is also the one Adguard is hosted on. There is only one IP for that server.

Do you think I should buy another VPS, install Cloudron on it and install either my VPN or Adguard on it and try with that?

Yes, I think this will work (because from our experiments using 8.8.8.8 clearly worked).

I downloaded the default openvpn file from my cloudron vpn app (I did not change any settings in the app) and then added these 3 lines to the ovpn file to force my dns server...

dhcp-option DNS ~IP OF MY SERVER~
register-dns
block-outside-dns

Unfortunately that didn't help. Thank you for trying though. I already bought the new VPS too so we shall see if this works. Cloudron just got installed so I'm going to attempt to install OpenVPN first and if that doesn't work, ill install AdGuard Home

Having a secondary server with Adguard on it works. I assume some configuration on the original Adguard server broke because the OpenVPN on the secondary server still couldn't connect with my main server Adguard.

Thanks guys for all the help, this can be marked as resolved.

Good to know these! Apparently, these are Windows only directives - https://iflorian.com/openvpn-block-outside-ds/

Cloudron makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server. Find out more or install now.
