My sonos device on local network not detect when connected to AirVPN with Eddie

[King0777 0]

I'm using Eddie 2.4 to connect to AirVPN on my phone running Android 10.
I've checked the option to exclude local networks from VPN.
When connected, my sonos device is not detected by the Sonos app (using sonos s1 because my device can't be used with the new s2).
A traceroute to my device shows that I'm outside the VPN :
traceroute 192.168.0.200  1?: [LOCALHOST]                      pmtu 1500  1:  192.168.0.200                                        91.003ms reached  1:  192.168.0.200                                         1.934ms reached      Resume: pmtu 1500 hops 1 back 1

When I'm using an AirVPN generated profil on de.blinkt.openvpn v0.7.21 (with some adjustments like routing local networks outside the VPN) instead of Eddie, my sonos device is working.

In Settings > VPN, try disabling VPN Lock.

No, Sonos is still not working with the vpn lock disabled.

Okay, then try using your local DNS server with the VPN. In Settings > DNS, enable Use custom DNS, then enter your local DNS server in Custom DNS.

Thanks for the help, my previous response was a bit dry.
So, no, with the dns set to it's value when I'm not using the VPN, the sonos app is still not finding the speaker.

I just found something interesting. The openvpn app with which sonos is working is using openvpn 2.x. You can configure it to use openvpn 3 core, in that case, Sonos is not accessible.
Eddie is using openvpn 3.3 :  I just have to say that the Eddie client on my windows 10 laptop does not have the sonos problem.

That is indeed.. interesting. If it's in the code, there is no way to configure it away.. 😕

I've just checked, eddie 2.19.4 that I use on windows is using openvpn 2.4.9. I think that's why Sonos is working.
Openvpn 3+ is still experimental, maybe eddie on Android should reverse to openvpn 2+.

Edit:
I've just realized the problem is not only sonos.
None of my local network is accessible.
To be sure the problem was not coming from my tinkering with eddie, I reset the app data.
I just set the master password, save the login info and activate the local network access setting.
When connected, I can't ping my router on his local ipv4, I can't access my ssh server on it's local ipv4.
I've configured a port redirection rule to access my ssh server from the outside. I can connect to my ssh server by using my public ipv4 (the connection is going through the VPN).
If I add a directive to keep the access to my public ipv4 outside of the VPN (route X.X.X.X 255.255.255.255 net_gateway), I can't connect to my ssh server using the public ipv4 anymore.

I'm opening an issue on the git repo. Edited ... by dragoworld235

Hello!

Changing Eddie to make it run OpenVPN 2 is a problematic matter, because OpeNVPN 2 is not a library, while OpenVPN3 is. By avoiding to run an external binary Eddie Android edition complies to security best practices as well as Google requirements in latest API.

Anyway OpenVPN3-AirVPN library is not OpenVPN3. It's a fork which is 90 commits ahead of OpenVPN:master and had many important bugs fixed. An updated Eddie Android edition using our latest library version might be a Christmas present to you all, while you will see very soon an updated Hummingbird (which also calls OpenVPN3-AirVPN library) for Linux and macOS.

Kind regards

Tanks @Staff
Do you think it's a good idea that I open an issue on https://gitlab.com/AirVPN/EddieAndroid for the problem with accessing local network with openvpn 3?
As you said, you're using a customize version so maybe you can fix the bug and submit the patch to OpenVPN ?
I will open an issue with OpenVPN for that problem.

Hello!

Yes, please open an issue in our git.

Do you want to open an issue for OpenVPN3 main branch too because you see the very same problem with latest "OpenVPN for Android" when it is configured to work with OpenVPN3?

Kind regards

As the problem is clearly coming from Openvpn3, yes I will open an issue on their github.
I was just wondering if creating an issue on your gitlab repo was needed or if that forum topic would do the trick.
You have answered to me. I will created an issue without every elements I have (screenshots, routing table, ...) and I will add them as needed. Edited ... by dragoworld235
