It works fine if you set everything up properly, but since many
clients will use passive mode by default to get through NAT, you will
need to forward a port range for passive mode use and configure your
FTP server to use that port range.
Unfortunately, as far as I know there's no (easy, anyway...) way to
have the firewall/NAT rules triggered automagically when a PASV
request is made, so those ports will always be open to the internal
machine, which might cause you other certification issues. I seem to
recall that when I was using Linux iptables to do NAT there was an ftp
connection tracking module that could do this automatically, but as
far as I can tell FreeBSD (or at least pfSense) doesn't have this
capability.

How portable is this to various ftp clients? I've done this in the
past but it failed with some ftp clients, as I recall.
