As a rule I run my local network behind several nat'd firewalls. Its a good thing. As for what os I am using to ftp into the servers network it's XP Pro. The problem I think has to do with the PASV settings and how it relays the port settings to the remote host. I think? What I have for the port settings are : FTP port 54321 for PASV ports 54322 - 54332 on the hosts static ip address. I have the gateway set to forward those ports to the next router or the gateway for the server's network. The same ports are forwarded to the FTP server. I can only set the ports coming into the networks. I assume that when the connection is established the server sends the port configuration to the remote host and the PASV mode is then set up. It seems to work but I still cannot view the files. It works fine on the server using Explorer Browser as FTP;example ftp://usernameassword@serversiportxxxxxx
where the ip is not the loopback interface. I hope someone can help?
