You will have to replace 200.200.200.0/24 with the CIDR that you are
using for your Neutron external network (that provides the floating IPs).

The eth0 in the guide is the interface on the gateway node that provides
connectivity to the Internet. eth0 is just an example, the interface
name may of course be different on your system.

No, because the outgoing traffic will be NATed and masqueraded by
iptables. The uplink router thus will see the packets as coming from
eth0's IP address.

No. MidoNet's datapath would then grab all of eth0's traffic and things
will get messy in the underlay.
