You will no doubt get several responses to this, but...
use FORWARD instead of INPUT
INPUT and OUTPUT only affect traffic directly flowing in and out of the
firewall server itself. FORWARD affects all traffic flowing through it.
Also (and this is probably a typo only in this email) you have a space
between "-" and "A" that should not be there
ie "iptables -A" not "iptables - A"
