Digi Connect ME4 9210 behind a firewall. What's the easiest way to get the data it's reading?

This device (SLR-350N AIS Receiver) has a Digi Connect ME4 9210 in it. It reads data form the antenna. What’s the easiest way to get the data from this device when it’s behind a firewall, without reconfiguring the firewall to allow inbound traffic? Can the ME4 9210 be configured to upload the data it reads to the devicecloud? Or is there a way to telnet to the device through the device cloud? Any suggestions appreciated.
