You didn't state what the problem was but I will assume that the MASQ isn't working.
The thing that gets most people is:
echo 1 > /proc/sys/net/ipv4/ip_forward

Even though the /etc/sysconfig/network file says "FORWARD_IPV4 true", if this file has 
a zero in it, your stuck.

Hope that helps. Let me know.
