Opening the high order ports is a security risk. This is a long
standing problem with the FTP protocol.  If you are going to have a
FTP server on your FBSD box being accessible from the public
internet, you should be using the built in FTP proxy in ipfilter
firewall. The ftp proxy option only opens the single ftp data high
order port number being used.  This is much more sure than exposing
all the high order ports.

Then you should enable in/outbound traffic on your xl0 interface,
the ports from 49152 through 65535, used for the data-channel
