While I agree with blars mostly, that's not usually the issue, Passive FTP is built to work with NAT and it's the most common type of FTP you see these days. I do agree tho, if you can move off of FTP you would be better off, but only because of security, basically FTP is 100% not-secure. SFTP is secure, as well as SSH.<br><br>But the real problem is, it's a firewall on the WIFI provider that just blocks the traffic. There is nothing you can do about that, if they block the traffic, they block the traffic. It's totally hit/miss as to which do and which don't.<br><br>By and large I've found the ATTWIFI (so Starbucks, McDonalds, etc) generally allow stuff like FTP. Libraries usually do as well. Target's usually do. But it's totally hit/miss as to who will allow it and who won't.<br><br>You *could* do a http tunneled VPN to get past the firewall, but it takes a bit to get that all setup correctly, and it's sort of outside the scope of what the WIFI provider wants you to use their network for. I'm of the thinking, they put those blocks in for a reason, and rather than circumvent their protections, I just find a different WIFI, or use my Verizon MIFI device.<br><br>Regardless, I wish you lots of success on your adventures!<br><br>With Love,<br>Tara
