Edit ConfigServer Firewall - Doesn't work

[r4nm4]

Hi,
I've installed the "ConfigServer Security & Firewall - csf v6.08" plugin on cPanel.
It's very beautiful plugin! The option "Check Server Security" it's amazing!

I'm sorry, but I've an a problem with the option "Edit the configuration file for the csf firewall and lfd".
When I changed the option value, for example "TCP_IN" and "TCP_OUT" value and click on the "Change" botton,
the plugin save the new value, but the new IPTables rules doesn't work.

I want close port 21.
I write:

# Allow incoming TCP ports
TCP_IN = 20,22,25,53,80, more...
TCP_OUT = 20,22,25,37,43,53,80, more...

But the port 21 it's always open. Why?
How can I do?

I'm so so so sorry for my english :(

Thank you!!!
Best regards

Did you restart CSF?

Of course

You should also delete 20 from that list.

What indication do you have that 21 is still open.

Is your IP listed in csf.allow?

Hi Sawbuck!
Thank you for your help!
I'm so so sorry for my stupid error.
The problem was in "csf.allow"
Thanks
