Cute problem solved.I had set the table, "mangle" to DROP and didn't realize that everything goes through this table. Since I'm not using NAT I was ignoring that table.
I was taking notes from a book and realized that the guy who wrote it made one mistake. But put all the tables to a default Policy of DROP which isn't really the way to go. IIRC only the table, "filter" should have the default of DROP. Probably to avoid stupid questions on the internet... :)
Thanks to all who responded. Now I just have to figure out how to get FTP straightened out.
