Hey Gabe:
I know for iptables you have to echo 1 to the special file
/proc/sys/net/ipv4/ip_forward
With all my ipchains/iptables scripts, at the very top I have:
IPC = /usr/local/sbin/ipchains
echo "1" > /proc/sys/net/ipv4/ip_forward
$IPC -f ACCEPT
$IPC -f FORWARD
<SNIP>
I am talking about redhatland here, but the same might apply to debian. Dunno
tho. I know that in redhatland, you _must_ echo that 1 to that file, otherwise
it doesn't matter what kind of rules you set up, because forwarding is not
'going on'.
