What is the value of /proc/sys/net/ipv4/ip_forward ? You either have
to set "ip_forward=yes" in /etc/network/options or do something like
$ echo "1" > /proc/sys/net/ipv4/ip_forward
If forwarding is already enabled then please send the output of
"iptables -L -v -n". IMHO this is easier to read than shell-scripts
written by other people. Regards,
