Describe the problem

Today I've deployed a new setup which has separated IDP based on Zitadel and Netbird which I've configured using advanced configuration guide. I have one server in a cloud which has docker installation with couple of services and netbird agent installed in the same network with docker services. I've deleted default access policy rule and added custom one, which allows the only UDP traffic.

I've added a new route with peer and the docker network.

And traffic began to flow from User peer to OracleDC peer, but not the traffic which is limited by the access policy rule, but any traffic. So, in this case I allowed the only UDP traffic, but I can ping hosts in remote network and access to the services on 80,443/tcp ports.

To Reproduce

Steps to reproduce the behavior:

  1. Deploy a new service
  2. Add some peers to different groups.
  3. Create network route which sits behind one of the peers.
  4. Delete default access policy and create a new one which limits the access to the peers with network routes.
  5. Feel free to access to any resources in the route without limitations of created access policy.

Expected behavior

Limited traffic according to created Access Policy.

Are you using NetBird Cloud?

self-host NetBird's control plane.

NetBird version

0.26.3

Thank you
