Accessing Local Network Devices over the Internet

  • 772

Here's a diagram of the Network Setup I am trying to accomplish:

enter image description here

So we have offices with LAN-connected devices that we need to access remotely.

Initial solution is to try using ZeroTier(ZT) installed in a Ubiquiti EdgeRouter X (UBNT) device.

So I managed to install ZT with the UBNT via its Linux-based EdgeOS and SSH:

ubnt@ubnt# sudo -i
root@ubnt:~# curl -s https://install.zerotier.com | sudo bash

And got to access the Edge OS (Edge Max) interface through the ZeroTier Global IP, so I can access my router anywhere/remotely.

However, how can I "remotely" access the LAN devices connected to the router? For example, I have one device connected to eth1 with Local IP in the router, 192.168.1.39

How can I access this using the ZeroTier network?

Here are the interfaces in my EdgeRouter X:

ubnt@ubnt:~$ show interfaces
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface  IP Address            S/L Description
---------  ----------            --- -----------
eth0     192.168.0.157/24         u/u Internet
eth1     -                 u/u Local
eth2     -                 u/D Local
eth3     -                 u/D Local
eth4     -                 u/D Local
lo      127.0.0.1/8            u/u
       ::1/128
switch0   192.168.1.1/24          u/u Local
ztzlgezugz  10.148.18.15/24          u/D
       fcf0:4d28:e363:18fd:910f::1/40

What could be missing in my software and hardware setup to allow the LAN devices to be accessed over the internet?

UPDATE:

I also want to emphasize that the Local Instrument/Devices mentioned in the diagram are devices that we cannot install any software into it, neither how the it's network operates. Example are Printers, Scanners, Imaging Devices, NComputing Terminals, etc. We can only access it via LAN.
