Is this behavior normal? I have seen the same thing. I think what is happening is that when you restart networking, it disables packet forwarding. When you start it, it will re-enable. After you start the network type: "/sbin/sysctl net.ipv4.ip_forward" I expect that you will see "net.ipv4.ip_forward = 1" Please confirm. Barry
