Broadband access

I have used SmartFTP on my network at home (Hughes) and at various truck stops (SiriCom). I have not had any troubles. I recently purchased a Verizon Broadband card and I have not had any troubles with the browsers. I tried SmartFTP and I cannot connect to an IP that I need to. I tried to also ping the IP and it failed. Could the Verizon Network be blocking the IP or is their a setting I need to check on in the SmartFTP to enable Broadband access via a plug in laptop card?
