I'm not sure if this will be of any help to you folks, but I have had to
do this in the past.  The /proc file system contains a file called
ip_forward which has to be echoed with a "1".

echo 1 > /proc/sys/net/ipv4/ip_forward

Try that, or, see what that file is not.  If its a "0", then thats what
your problems are.
