i dont see how things are obvious for you as they not so obvious for me.
first of all my ipf default policy to allow everything.
so the original question is for ipnat and not for ipf
now for non-passive (active) i put in these rules
rdr bce0 0/0 port ftp-data -> lama port ftp-data tcp
rdr bce0 0/0 port ftp -> lama port ftp tcp
and for pasv i still dont know what to do
rdr bce0 0/0 port 49152-65534 -> lama port 65534
and in my ftp i said that this is range for pasv connections
yet i'm able to make a connection (but that goes through ftp/tcp(21))
and whenever i enter into pasv it stops working...
