The ip address specified in
http://i.imgur.com/8uPPosw.png is 173.175.11.124, so this is presumably your current WAN ip address.
The ip address specified in the DNS-323 ftp page
http://i.imgur.com/8EPipWm.png is 70.122.123.130 - this should be your current WAN address so I would expect to see 173.175.11.124 here, and you need to check the box for "report external ip in passive mode".
To have that sort of difference in the WAN ip addresses I would like to think you have perhaps changed your ISP or your geographic location.
Ideally your passive port range should not overlap the non standard ftp port you are using and the range chosen also needs to be forwarded to the DNS-323 - I would suggest you use the default port range (there is a radio button for it in the DNS-323 ftp setup), don't forget you need to forward the non standard ftp port (1025) AND the passive port range.
