Lan network through the WAN interface

[Phobbos]

Hello everyone.

Please help me with what I hope is a simple issue.
I am currently working from home because of the Covid -19 fun!.
I am working on a project with a work mate (who is also at home). What I want to do is have his PC and my PC on the same network. We are working on a project that uses a client/server setup. So he need to "download" information to my machine.

This is a siemens SCADA system, and normally the server and client sit in the same room, on the same lan network, but obviously we are stuck :(.

So very basically we need the machines to think they are on the same network.

Please can you tell me how to go about this. I am also not a network guy so please type slowly so that I can understand ;)

Cheers

Hi,

if you need Layer2 connectivity you may want to implement this: https://docs.netgate.com/pfsense/en/latest/book/openvpn/bridged-openvpn-connections.html

Warning: this may break your current VPN-config!

Recheck if your Siemens really need layer 2.
With layer 3 you could run any default Site to Site VPN like OpenVPN in tun mode.
