[ale] FTP weirdness

[Leonard Thornton]

Is your Linux box you are going through your firewall/NAT box?  With your 
Linux clients that work through this box, have you tried setting PASSIVE 
mode off and seeing if they work?

If this box IS a firewall/NAT box, you need to make sure that ftp-data port 
is open inbound AND that it is MASQ'd properly.  Look at elofw.sh out on 
www.linux.org for an example of how to do this....You can test this by 
setting your Linux ftp clients to use ACTIVE mode rather than PASSIVE for 
transfers.  If this is your problem, your Linux clients will failed in 
ACTIVE mode.

Hope this helps.
