On EC2, each instance (Xen DomU) gets an internal IP address (usually 10.x.y.z) and also a public IP address which is NAT'ed to the internal IP address. I am assuming that this NAT happens in Dom0.

In XCP, the DomU VIFs are directly bridged to the physical network -- this would be the internal IP equivalent. I don't see any equivalent way to NAT the public IP address to the internal IP address. With xend-style networking it may have been possible to use network-nat or perhaps network-route

vi /etc/xen/xend-config.sxp
(network-script network-route) 
#(network-script network-bridge)
#(network-script network-nat)

Is it possible in XCP?

So really all you want is for your public IP to be routed to your vif and back?
