Enable ProFTPD mod_ban

[warri]

Hello,
I was wondering how to enable the Banengine from mod_ban.

In the default proftpd.conf it is disabled:

Code:

<IfModule mod_ban.c>
  BanEngine off
  BanControlsACLs all allow group wheel
  BanLog /var/log/proftpd/ban.log
  BanMessage Host %a has been banned
# -m "mod_ban/rule"
# -v "concat('  BanOnEvent ',event,' ',occurrence,'/',timeinterval,' ',expire)" -n
# -b
  BanTable /var/run/proftpd/ban.tab
</IfModule>

But even if I add a new IfModule section in the auxiliary parameters, it obviously won't overwrite those settings.
I tried to add this lines to the auxiliary parameters section:

Code:

 <IfModule mod_ban.c>
    BanEngine on
    BanLog /var/log/proftpd/ban.log
    BanTable /var/data//proftpd/ban.tab
    BanOnEvent MaxLoginAttempts 2/00:10:00 01:00:00
    BanOnEvent ClientConnectRate 2/00:01:00 04:00:00 "Stop connecting frequently"
</IfModule>

So in the GUI there seems to be no way to enable the banengine, can I configure it somewhere else?

[edit]
I managed to adjust my rc.d/ix-proftpd to enable the banengine, create a ban.tab and a ban.log and add the correct rules.
But proftpd isn't banning at all. So, is the module not included in FreeNAS 8 so far or did I miss anything else?
