Queue all traffic...even if not destined for local machine
Hello all, me again:
I have a box with two Nic cards on it. What I will be doing is taking
a packet coming in on one nic, encapsulating it, and then sticking it
on the other card. I know how to Queue traffic destined for that
machine (iptables --insert INPUT 1 --in-interface eth+ -j QUEUE). But how do I
get traffic not destined for itself? --insert FORWARD 1 doesn't seem
to work. I enabled forwarding by (echo 1 > /proc/sys/net/ipv4/ip_forward), is there something else I need to do?
Do I need to look at promiscuous mode?
Thanks for the help.
