DNS/Routing Problem in Linux Client on openSUSE Tumbleweed

[JackGin]

Hi guys,

I would like to extend my gratitude for your exceptional work in developing the Amnezia VPN project.

I am reaching out to report a potential bug I've encountered with the Linux client, specifically when operated on openSUSE Tumbleweed. Although the client successfully establishes a connection to the server, it appears to be facing a DNS/routing issue.

More precisely, while I am able to ping any IP address successfully, DNS resolution seems to be failing as I cannot access websites through a web browser. This issue persists regardless of whether Amnezia DNS is enabled or disabled.

I have tested this with two different versions of the client (4.1.0 and 4.2.0), and have experimented with both Amnezia WG and OpenVPN over Cloak protocols. Interestingly, the client functions without any such DNS issues on Android and Windows platforms when connecting to the same server.

I understand the complexities involved in maintaining cross-platform compatibility and appreciate any efforts you can make to investigate and resolve this issue. Your support in this matter would be greatly appreciated.

Turns out to be an issue with resolv.conf. Thanks once again. Closing.

Could you, please, tell, how did you fix this issue? I have the same problem.

Assuming you're using NetworkManager:

• Disable Automatic DNS Configuration: Add the following lines to /etc/NetworkManager/NetworkManager.conf:

  [main]
  dns=none

  This prevents NetworkManager from automatically managing DNS configurations.

• Replace everything in /etc/resolv.conf with this:

  nameserver 1.1.1.1
  nameserver 1.0.0.1

  Now you should be able to browse the web.

Amnezia works poorly with NetworkManager, try other network manager like systemd-networkd or another alternatives https://wiki.archlinux.org/title/Network_configuration#Network_managers
