The ftp-proxy tool is only used in one of these two situations:
  1. OpenBSD with PF is acting as a NAT router (firewall) and you wish FTP clients on your private network(s) to access external FTP servers.
  2. OpenBSD is running on a private network behind a NAT router, where PF is being used to protect the FTP server..
Configuration guidance can be found in the PF User's Guide, in the chapter titled "Issues with FTP." Here is a link:

http://openbsd.rt.fm/faq/pf/ftp.html

You'll find configuration guidance for situation #1 under FTP Client Behind the Firewall, and guidance for situation #2 under FTP Server Protected by an External PF Firewall Running NAT.
