Originally created by @netandreus on GitHub (Nov 1, 2024).

Describe the problem

After adding exit peer route Internet access disappears.

To Reproduce

I have two peers:

  • first one (peer-1) Windows VM I use for testing (whatismyipaddress.com)
  • second (peer-2) Ubuntu 18.04 VM I use as an Exit Peer. I made distribution group (Exit-TR) for it.

Before adding "Exit-TR" Distribution Group to peer-2 I have an Internet access.

Screenshot 2024-11-01 at 09 49 08

When I added Distribution Group to the first peer the route arrives, but the Internet stops working.

Screenshot 2024-11-01 at 09 53 03

Expected behavior

Routing through the exit peer.

Are you using NetBird Cloud?

I use self-hosted version of NetCloud.

NetBird version

netbird 0.30.3

Do you face any (non-mobile) client issues?

Please provide the file created by netbird debug for 1m -AS.
We advise reviewing the anonymized files for any remaining PII.

Here are the logs:

@netandreus can you please test with 0.31.0 and if the problem persists, run the netbird debug for 1m -AS again?

@mlsmaycon should I update server only (amangement etc), client or all of them?

I'm also having the same problem on both Netbird self hosted and cloud editions. My client versions on both ends are 0.31.0 and I don't have any firewalls.

Having the same issue even with the Netbird Enterprise account. There is a definitive bug around windows clients. We made numerous tests and for some reason exit node bombs the clients with UDP packets and choke them until they get disconnected. During this time [kworker/1:3+wg-crypt-wt0] process at the exit node hits %100 CPU.

@mlsmaycon commented on GitHub (Nov 5, 2024):

@netandreus we will check your logs and give you a feedback soon. It seems like we have a constant route update in the logs that needs more time to investigate. In the mean time, can you test both, routing peer and windows client running on NetBird v0.28.9?

On ubuntu you can run:

apt-get install netbird=0.28.9

the windows installer is: https://github.com/netbirdio/netbird/releases/download/v0.28.9/netbird_installer_0.28.9_windows_amd64.exe

I can also confirm when version 0.28.9 is used on Windows clients and 0.31.0 on exit node, everything works fine.
It seems latest Netbird client is messing with something on Windows but I'm not sure.

@eoksum In my case it only works when version 0.28.9 installed on both peers (exit node and client node). When I'm updated netbird from 0.28.9 to 0.31.0 on the exit node Internet access disappears.
