I've beeen using Verizon DSL for a couple years now and have had no probs at all. I am interested in sending files from my work computer to my home computer. Initially, i installed a copy of Guildftp for the ftp server and tried:
What connects your home PC to Verizon (is PPPoE on your PC or is it behind a NAT router)? Maybe that is blocking ping. Maybe that is blocking or not forwarding port 21 to your home PC.
Is your work PC behind a NAT router, or does it use a proxy?
There may be a problem connecting ftp-data port 20 for ACTIVE mode or other random ports used for PASSIVE mode. But I forget which way those ports need to be open.
I know I had trouble just trying to use an ftp client behind a broadband router in ACTIVE or PASSIVE mode unless I set that PC as DMZ in router. But I now use Linux as pppoe/firewall/router which with proper settings can properly handle ftp.
