LAN to LAN traffic between peers not working

[Ignattious]

Describe the problem

2 Peers

Netbird A
Netbird B

Each peer / site has 1 LAN attached:
A 10.1.100.0/24
B 10.1.101.0/24

Can ping between:

Netbird Peer Site A to LAN B (Using Netbird 100.190.x.x source)
Netbird Peer Site B to LAN A (Using Netbird 100.190.x.x source)

Cannot Ping from Peer A LAN to Peer B LAN (Using LAN IP source)
Cannot Ping from Peer B LAN to Peer A LAN (Using LAN IP source)

To Reproduce

Add 2 Peers
Add Resources
Add Resource to Routing Peer

Expected behavior

Should be able to route between LAN networks using 2 ore more routing peers

Self Hosted
netbird version 0.52.2
No Other VPN software

Can see packets going over wt0 tunnel but get dropped on routing peer before going into LAN network, If the source is a netbird 100.190.x.x address from either end packets are transferred normally.

Policy should be allowed to be created to allow LAN networks from 2 different peers to communicate. In some cases, it is impossible to install netbird on all machines and we must rely on routing peers to provide communication between 2 different networks

Tailscale has similar functionality:

Netbird, to my knowledge, does not have this feature. You can publish a site to a client/group of clients, but not a site to site.

@Ignattious ,

Out of interest, are your A & B peers also the gateways for their relevant LANs?
(such as pfSense/OPNsense perhaps)

@stildalf , I have the same problem, and A & B are the gateways for their relevant LANs for my scenario. Any insight would be appreciated. thank you.

You have to set a static route on your default router for the other side and route it to your local netbird router.

i never tested this but for my understanding this should work.

Edit: but when i think about that, this is not the concept of ZTNA. How should policies checked when the user are unknown.
