Hello,
I want to do the following, accept in comings from 10.2.2.115 only
restricting to port 80,22

is this correct? 

-P rules ...
-F rules ...
/sbin/iptables -A FORWARD -d 10.2.2.115 -j ACCEPT
/sbin/iptables -A FORWARD -s 10.2.2.115 -j ACCEPT
/sbin/iptables -A INPUT -s 10.2.2.115 -j ACCEPT
/sbin/iptables -A FORWARD -m multiport -p tcp --ports 80,22 -j ACCEPT
/sbin/iptables -A INPUT -m multiport -p tcp --ports 80,22 -j ACCEPT

Eventhough i saw this setup in many tutorials/howtos,  when ever i want
to block 10.2.2.115 (by not listing him in the INPUT -j ACCEPT), that ip
can still connect to port 80 and 22.



Thanks
Sincerely,
