I set the network interfaces of my network node follow the doc on http://openstack.org eth0 used for external network, the IP address is allocated by the lab's admin, it is fixed. When I change the /etc/network/interfaces to auto eth0 iface eth0 inet manual up ip link set dev $IFACE up down ip link set dev $IFACE down and reboot I cannot ping the http://openstack.org WHY? Because this configuration is used for DHCP situation? What should I do to make it can connect the Internet?

I have the same issue until configure the network eth0 with a fixed ip and enable ip forwarding, I can't understand how the "auto eth0 iface eth0 inet manual up ip link set dev $IFACE up down ip link set dev $IFACE down" will work for internet accessing....who can explain?
