Desperate for Help WIth FTP Problem

We have an application using pure FTP in a shell program. The program works fine with my home WIFI – in fact it works with everything but the embedded card. Windows firewall is not an issue.

The problem seems to be with either Gobi2000 or Verizon. Verizon insists there is nothing on their end. (Computer is Motion Slate.)

The problem exists when running FTP from command line too. I AM DESPERATE!!!!!! ANY THOUGHTS?????
