Windows 2008 servers:
Install loopback interface and give it the shared ip.
the internet connection ip is called net here (interface name) and the loopback device is renamed to "loopback"
To allow the server to send as the loopback apapter on another NIC you need to use this:
netsh interface ipv4 set interface "net" weakhostreceive=enabled
netsh interface ipv4 set interface "loopback" weakhostreceive=enabled
netsh interface ipv4 set interface "loopback" weakhostsend=enabled
