Shared folder behind the WAN side

Is it possible to send data from the LAN side of the Ewon network trough the WAN side?

For example.
Pc customer (192.168.0.25)
Switch customer(with internet)
Ewon (10.0.0.53)
Machine(10.0.0.1) LAN

How can i setup the ewon to reach 192.168.0.25 with the machine 10.0.0.1?

You can use NAT 1:1 to map the machine (10.0.0.1) to the WAN network. This will allow that machine to be accessed on the WAN side since it will have a WAN IP.

i tried this but it doesnt seem to work.
I did everything in that pdf but it doesnt seem to work.

I think this is the other way… from WAN to LAN?

Yes that is what it sounds like. WAN to LAN is not possible. We can only pass data LAN to WAN. So if you had something trying to pull data or access a device on the LAN then it is fine, But if that LAN device was something like a computer trying to access a drive on the WAN network then that would not work since that drive is on a different network and does not have a LAN IP.
