Cannot ftp through windows firewall on sbs2008

I have a strange problem.
Windows firewall is blocking my ftp site.

If I turn off firewall, everything works fine, but as soon as I turn it back on, I will not be granted access.

I have FTP Server in my exception list.
I have tried to add port 21
but no matter what I do the problem is the same.

Can anyone tell me what need to be done, to get it working with Firewall turned on?

If hosting, see: under the 'Using Windows Firewall with non-secure FTP traffic' section. You need to perform the netsh commands
