Shared Folder via WAN IP - wrong network password

Question

Hello,

We are using Windows 10. In the Network Firewall we have enabled 1to1 NAT Reflection, so that Windows machine can access its ports via its WAN IP Address as well. It is working fine, so accessing the softwares via WAN IP from the Windows machine is working fine.

But when we want to access the shared folder via WAN IP from the Windows machine where the folder is shared, it asks for username and password, but it gives an error - wrong network password. Could you please let me know why it happens and how to solve it? Thanks.

For example:

WAN IP: 1.1.1.1

Internal IP: 192.168.0.100

Shared folder path: \1.1.1.1\sharedfolder
