<iptables_manual>
filter This is the default table (if no -t option is
passed). It contains the built-in chains INPUT
(for packets coming into the box itself), FORWARD
(for packets being routed through the box), and
OUTPUT (for locally-generated packets).
nat This table is consulted when a packet that creates
a new connection is encountered. It consists of
three built-ins: PREROUTING (for altering packets
as soon as they come in), OUTPUT (for altering
locally-generated packets before routing), and
POSTROUTING (for altering packets as they are about
to go out).
</iptables_manual>
Çünkü iptables'in manual'ından da anlayabileceğimiz gibi PREROUTING filter
değil nat tableinda kullanılabiliyior.
İyi Çalışmalar
