You need to add a rule for the FTP proxy. Something like:

  map net0 10.0.0.0/24 -> realip/32 proxy port ftp ftp/tcp
  map net0 10.0.0.0/24 -> realip/32 

(I've answered this one a few times recently. A Google search for 
"peattie ipnat ftp" will turn up the details - perhaps Tony could add 
something to the notes on his page?)

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
