Describe the problem

Setting extra dns labels is only possible via netbird up, which as far as I understand will require creating new setup key, and will lead to peer IP address change, reconnect with downtime, etc.

To Reproduce

N/A

Expected behavior

DNS labels can be updated dynamically via dashboard

Are you using NetBird Cloud?

Self-hosted

NetBird version

0.51.2

Is any other VPN software installed?

No

Debug output

N/A

Screenshots

N/A

Additional context

Have you tried these troubleshooting steps?

  • Reviewed client troubleshooting (if applicable)
  • Checked for newer NetBird versions
  • Searched for similar issues on GitHub (including closed ones)
  • Restarted the NetBird client
  • Disabled other VPN software
  • Checked firewall settings

@gza commented on GitHub (Oct 1, 2025):

Also:

  • On big setup with multiple teams, granting to a setup key the right to set any DNS label is a security issue:
    • By mistake or maliciously, one can get the traffic that was supposed to be sent to another service.
    • I would recommend in the "Setup Keys" UI to allow to set a kind of wildcard/regexp to limit which DNS label can be set later by the key user.
  • On non-Kube environment, the deployment of a new service with a new DNS label requires to change the key and cut the VPN for a moment.
