and was so noted. wherein, a little more info would be nice.

did blocking work with;

  [1] iptables -A INPUT ! -s -p tcp --dport 21 -j DROP
  [2] iptables -A INPUT -s ! -p tcp --dport 21 -j DROP

syntax tends to indicate that [2] is correct, as [1] would tend to
indicate "NOT source".


peace out.
