look at /etc/sysctl.conf for
Code:
# Controls IP packet forwarding
net.ipv4.ip_forward = 0
if it is 0, RHEL won't forward (route).
To see the current value set for the running kernel
Code:
cat /proc/sys/net/ipv4/ip_forward
if it is not 1, set it to 1 with
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
and test connection from client to Internet again.
This is the most likely, but not only possible item preventing traffic from being routed. If the above looks good (or does not work after setting ip_forward = 1) then we'll need to look elsewhere... such as firewall settings.
