Originally created by @sgtaziz on GitHub (Mar 18, 2024).

Describe the problem

On a self-hosted installation, all clients have a "Public IP Address" set as the docker network gateway. Using "host" network mode for the management service changes that IP to 127.0.0.1.

To Reproduce

Steps to reproduce the behavior:

  1. Self-host netbird
  2. Join a peer
  3. Open Peers page on Netbird UI
  4. See peer IP Address and Region "Unknown"

Expected behavior

Peer IP Addresses should be correctly set. Perhaps from the COTURN server?

Are you using NetBird Cloud?

No, self-hosted

NetBird version

netbird version
0.26.3

I have the same problem on almost all my docker hosts with a single exception where the correct ip is displayed.

Update: rebooting the docker host helps. I tried it with two hosts and the public IPs are correct now.

Just to clarify, all my peers having this issue are normal clients. iOS, Linux, and Windows. The selfhosted instance is the only thing running on docker.

Turns out this was caused by the reverse proxy I was using (NGINX).
Below line fixed it:
grpc_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

Hi,

unfortunately this doesn't fix it for setups without reverse proxy. My "Public IP-Address" always shows the docker gateway for my netbird server on all linux peers. MacOS peers are not affected.

Can confirm, public IP is broken for almost all my docker hosts. Strangely, some do display the correct public IP.

I have the same issue. Someone above said MacOS peers were not affected, but mine are.

Guys, can you open a new issue and share more details about your setups? The IP address are checked using regular reverse proxy headers. So it will be important for us to learn what is your current setup, like are you using a reverse-proxy like nginx?
