Wireless issues in setting up an automatic download for a train system

Hi All,

I have been tasked to get a project back on track for a train locomotive system that has been installed, The system purpose is to automatically download logs from the train to a SFTP (SSH) Server once the train is in the vicinity of a Access Point.

The layout of the system is

I can connect up with a laptop and copy a file to the SFTP Server.

However the loco is unable to connect to the SFTP server.

I can see the 3201 connect to the AP

The 3201 Config is Attached

I cannot ping the CMU and it cannot ping anything

My question is, should the Cisco 3201 IP be in the same subnet as the AP and why I cannot see the Alias address on the CMU if the Cisco 3201 is in bridge mode
