Need some help on setting up multiple NICs in my host

Hi,

I am running a Windows Server with multiple Xeon processors and 16GB RAM.

This host server has multiple NICs with 2 having active IP addresses assigned.

I need to install multiple virtual images (6) of Windows 2003 Server each with say 4 Processors & 2GB RAM.

I also need to assign atleast 2 NICs to each of the virtual images.

By default only 1 NIC is visible in the virtual image, however after adding an additional network adapter, I can see 2 NICs.

The IP configuration for all the VM images as planned is shown below.

1)  VM image 1

NIC1  192.168.1.10

NIC2  192.168.10.1

2)  VM image 2

NIC1  192.168.1.11

NIC2  192.168.10.2

3)  VM image 3

NIC1  192.168.1.12

NIC2  192.168.20.1

4)  VM image 4

NIC1  192.168.1.13

NIC2  192.168.20.2

5)  VM image 5

NIC1  192.168.1.14

NIC2  192.168.1.15

6)  VM image 6

NIC1  192.168.1.16

NIC2  192.168.1.17

Between 1&2, I plan to setup a VIP (Virtual IP) for NLB.

Between 3&4, I also plan to setup a VIP(Virtual IP) for NLB.

I need to know if I should use Bridging or NAT&Host only in the network options and will all the VM images be able to communicate across each other VMImage.

I do not have access to the local switch and hence cannot do any ARP / switch related confign changes.

Plz advise if this is possible and that all the the above VM images cannot communicate to each other at the same time.

Thanks

M.
