Yes, but because FTP is a pathologically evil protocol (at least as far
as firewalling and proxying is concerned :-) the SSH software needs
application-specific knowledge (ie the ability to decode the PORT
and PASV commands and act on them) in order to successfully forward it.
Not all clients have the ability. OpenSSH doesn't. I think the SSH.com
v2 clients do. Not sure about any others.

Apparently this does too.
