In addition to what Andreas said:

The problem is not the "router/gateway" in front of the ftp. The problem
is the internal address the ftp server has and the nat that the router has
to do. FreeBSD knows nothing about the external address... I think you'll
have better results getting a second IP address for your ftp server and
just route packets. Or you could search for an ftp server with this feature
and/or a router with a big bag of tricks(similar to ftp-proxy FreeBSD has)

I would go for a second IP address if that was a choice
