Describe the problem

I'm trying to replace the VPN with Netbird, but I encountered a very strange situation noticed that when trying to access some routes, the traffic is not going through the VPN. I haven't made any settings yet, I added the networks and added 2 exit nodes.

I configured one only for Netbird admins to use, the other one will be used by users.

To Reproduce

Steps to reproduce the behavior:

  1. Go to netbird client and click connect
  2. login with sso
  3. Trace tests are performed on some routes.

Expected behavior

I expect all traffic to go through the VPN, especially if an exit node is set.

Are you using NetBird Cloud?

im using self hosted netbird

NetBird version

0.59.12

Is any other VPN software installed?

Yes, WireGuard is installed on my computer (but I completely shut it down while doing these tests).

Debug output

NA

Screenshots

As you can see in the screenshots, the default route is not completely overridden by the VPN - the old gateway is still active. Normally we should see both of them in the default route.

The image below was taken when no VPN was active.

When VPN is actively used through the Netbird client, shouldn't there be an output similar to WireGuard client output? Why is it routing to my home router's gateway IP address?

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
