Right, dose firehol even load ip_conntrack_ftp? As you know, better then
me, is that ports= is where you specify what ports are for FTP. In
firehol you would just open thoes ports as if thay where for ssh ot http.

It might be worth looking into wather conntrack_ftp supports servers, last
time I looked it only worked for SNATed clients. It's only like 20 lines
of code to make it work for all four cases (SNAT|DNAT)ed_(clients|server).
If you get lucky I might submit a patch for it, thought I wonder why it
wasen't setup that way from day 1?

Your right. However DNS(53/udp) is requiered for host names to work at
all. firehol might by default set this up for you.
