Yes I did forward the hig port range 55000 - 65535 ports to port 21 and 20.
I am sorry I did not spell out all the configurations I attempted :(
I did change the vsftpd.conf file to the public IP so the pasv clients get
that back when they connect. The Public IP is static as well.
I did not use the Seever NAT Tab since I have 1:1 Nat configured
If I need to try that I will. My understanding is you use either Server NAT
or 1:1 Nat but not both. I do have the rules set otherwise.

Ok, so you opened * * all ports... did you FORWARD them to your FTP
server in the Server NAT tab?
Your FTP server should have an option wherein you can configure the port
range it uses for passive connections. Set that, and then forward (and
allow) only that range of ports to the FTP server. Also, the server
should have a setting that lets you specify the EXTERNAL IP address.
When clients use PASV, if the server is responding using its INTERNAL
(NATted) IP address, the client won't be able to do anything with that
as the address is (or should be) non-internet-routable. If you have a
static IP, you can set and forget, and if you've got a dynamic IP, you
will have to hope the FTP daemon has facilities for handling that.
