Netfilter/Iptables does not NAT all packets?
Hi all,
I am having a small problem with netfilter on Linux kernel 2.6.11.4. It
seems not all packets are hitting the pre-routing chain. In
pre-routing, I have the following rules:
$IPTABLES -t nat -A PREROUTING -i $IF_OUT -d 10.50.18.22 -j DNAT
--to-destination 192.168.1.22
$IPTABLES -t nat -A PREROUTING -i $IF_OUT -d ! 10.50.18.21 -m limit
--limit 5/second -j LOG --log-prefix "non-nat input: "
As you can see all packets arriving for 10.50.18.22 should be natted to
192.168.1.22, and anything else shoul...
