How I installed

curl -sSL https://pkgs.netbird.io/debian/public.key | sudo gpg --dearmor --output /usr/share/keyrings/netbird-archive-keyring.gpg
echo 'deb [signed-by=/usr/share/keyrings/netbird-archive-keyring.gpg] https://pkgs.netbird.io/debian stable main' | sudo tee /etc/apt/sources.list.d/netbird.list

sudo apt install netbird
netbird login --setup-key <...> --preshared-key <...>
netbird up --enable-rosenpass

Status

Problem

netbird local IP on this machine is 100.82.x.xxx

does not work: ping 100.82.x.xxx

another peer on the network is 100.82.y.yyy

obviously also does not work when I do ping from this machine (x) to another peer (y).

Beside this machine (Ubuntu 24.04), all my other peers (macOS, Ubuntu 22.04) are working fine.

Note: I am using netbird SaaS platform (not self-hosted).

Hi @pilinux,
Which groups are those peers inserted to? Do you have a Policy that allows communication between them?

Hi @mgarces
They all are in the default group. Bidirectional communication is on for all ports for the moment.

@mgarces commented on GitHub (Sep 27, 2024):

can you do a tcpdump on both ends, just to check if traffic is flowing in that direction?
Just for the sake of testing, please create a specific group for those peers, and create a new Policy just for them.
You can run the tcpdump with:

tcpdump -i any -nn host <NB_IP_ADDRESS>

On on end, replace the IP with the remote Netbird address, and on the remote, with your local Netbird address.
Also, can you paste here the output netbird status -d for both peers?

All machines are assigned to a new network on netbird cloud platform.

Machine A: working fine
Machine B: working fine
Machine C: doesn't work

On all three machines: net.ipv4.icmp_echo_ignore_all = 0

Machine A:

local ip assigned by netbird = 100.82.a.aaa
ping -I wt0 100.82.a.aaa => OK

Machine B:

local ip assigned by netbird = 100.82.b.bbb
ping -I wt0 100.82.b.bbb => OK

Machine C:

local ip assigned by netbird = 100.82.c.ccc
ping -I wt0 100.82.c.ccc => all packets are lost

@yakaviuk commented on GitHub (Dec 4, 2024):

Same issue for me,
I have few macbooks and mac mini which are connected to Netbird (self-hosted) network.
According to Netbird policy, ALL (TCP, UDP, ICMP) are allowed.
But ping and VNC (port 5900) connection doesn't work between macbooks and mac mini.

(but if they are in one local network without Netbird - ping, SSH and VNC work fine)

Hello @pilinux,

We're currently reviewing our open issues and would like to verify if this problem still exists in the latest NetBird version.

Could you please confirm if the issue is still there?

We may close this issue temporarily if we don't hear back from you within 2 weeks, but feel free to reopen it with updated information.

Thanks for your contribution to improving the project!

@pilinux commented on GitHub (May 1, 2025):

the problem is still there! u can test them easily. install on your mac. then install on an ubuntu (I used 22.04.5 LTS). they don't talk to each other even though both are connected to netbird platform.

Note: I switched to tailscale long time ago. Everything works as they should. I installed netbird again just to check whether this issue is fixed in the latest release or not. Maybe it is not related to client software, but on netbird cloud side?
