Originally created by @galiev on GitHub (Apr 7, 2025).

We have a self-hosted Netbird installation with nodes deployed in two regions (A and B). Clients within each region connect to the nodes in their respective region. Each region provides access to a unique set of networks. When a client from region A needs to access resources provided by nodes in region B, the nodes in region A currently forward traffic to the nodes in region B via Netbird connections over the public internet.

Our provider also offers a private, high-speed (10 Gbps), unmetered network between data centers hosting the nodes in region A and region B, the internet connection for each node is 1 Gbps, and even though the IP addresses belong to the same provider, the internet traffic between the regions is still metered and incurs costs.

We are looking for a way to force Netbird to use the private network for communication between the nodes in region A and region B, instead of routing traffic over the public internet, while still being accessible to clients on the Internet

Is there a mechanism or configuration option within Netbird that allows us to prioritize or enforce the use of this private network for inter-region node communication?
