Take note that if 'Private' access control type is selected, the nodes will only come online after they authorized by you from the ZeroTier Central dashboard. To learn how to authorize nodes, read the [[#Node_authorization|node authorization]] section of this article.

==Private network access==
This section provides instructions on how to set up remote access to private networks behind ZeroTier nodes. For the following instruction, we'll use an example ZeroTier network that consists of three members: a Teltonika-Networks device, a computer and a phone.
For the purposes of this example, let's assume we want to provide remote access for the computer and the phone to the 192.168.1.0/24 network behind the Teltonika-Networks device.

==Bridge Configuration ==
ZeroTier bridge configuration will allow two (or more) LAN's in the same ZeroTier network to be interconnected. For this example, we will use two RUTX routers. Both of these routers should already have the ZeroTier package installed and be connected to the ZeroTier Portal.
===First router===
----
*Navigate to '''''Services → VPN → ZeroTier''''' and access the ZeroTier Instance created previously to edit it for the bridging of LAN’s.
[[File:Zerotier Interfacev2.png|border|class=tlt-border|1050x1050px]]
*From the '''''Bridge to''''' dropdown menu, select '''''LAN'''''. This option bridges The ZeroTier interface with the device's LAN interface, which extends the network and allows for Layer 2 communication via ZeroTier. Bridges operate at the data link layer and facilitate seamless communication between devices on different LAN segments
*Save & Apply settings
===Second Router===
----
*Navigate to '''''Services → VPN → Zerotier''''' → and access the ZeroTier instance, configuring it the same way as the first router.
* Navigate to '''''Network → LAN → General settings''''' and change the '''IPv4 address''' to an IP that is in the same subnet as the first router (We will use 192.168.1.2 for this example)
*Navigate to '''''Network → Interfaces → LAN → DHCP Server''''' and Disable '''DHCP server''' option
*Save & Apply settings
[[File:Zerotier configuration rut 2 configuration v1.png|border|class=tlt-border]]
=== ZeroTier Portal===
----
*Open your ZeroTier Portal (https://my.zerotier.com/) and navigate to your ZeroTier Network.
*Scroll down to Members and enable '''"Allow Ethernet Bridging"''' option on both devices
[[File:ZeroTier Portal Bridging v1.3.png|500×200]][[File:ZeroTier Portal Bridging v1.2.png|500x200]]
*Make sure to turn off '''Auto-Assign from Range''' in the '''advanced section'''. Since this is a Layer 2 bridge configuration, there is no need for IP addresses on the ZeroTier Interfaces and managed IPs. With Layer 2 bridging, devices communicate directly using their local MAC addresses, eliminating the necessity for IP address management.
*'''NOTE: Make sure to remove any Managed IPs that might have stayed when the Auto-assigned feature was turned on (by default, ZeroTier keeps it on).'''
*In the '''Advanced section → Managed Routes,''' add the LAN network route (in this case, 192.168.1.0/24), which ensures communication within the bridge. This allows devices in the ZeroTier network to communicate with devices on the LAN.
[[File:Managed Routes.png||500×200]]
*To ensure convenience and avoid any IP or routing conflicts, it is recommended to remove any other automatically assigned routes in ZeroTier. By doing so, you can prevent routing issues and ensure smoother communication within the LAN bridge network of 192.168.1.0/24 over the ZeroTier Network.
If everything was done correctly, you should be able to ping devices connected to separate routers. Let us test this by pinging a laptop connected to the second router (192.168.1.163) from a laptop connected to the first router (192.168.1.220):

'''Note:''' If you wish to add more routers to the bridged network, you should configure them according to the second router configuration.
