Sorry, that was my mistake :-(
that happens. but does make things difficult to help.

actually I got the solution what was needed, from this list.
and was so noted. wherein, a little more info would be nice.

did blocking work with;

[1] iptables -A INPUT ! -s 172.16.158.111 -p tcp --dport 21 -j DROP
or
[2] iptables -A INPUT -s ! 172.16.158.111 -p tcp --dport 21 -j DROP

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



[2] worked for me ...by the way we need to indicate ! like '!' ( in
single quote)

iptables -A INPUT -s '!' 172.16.158.111 -p tcp --dport 21 -j DROP
