how to use different ip addresses for virtual os

[pipsta]

hi

i have a windows 2008 server from 1and1.co.uk and would like to run a few different windows server os's for testing, i have 3 ip addresses from 1and1.co.uk and was wondering how i can use a different ip address on each virtual os

i tried NAT and it just gave me the main server ip and i tried bridged but it just crashes out the connection and i have to reboot or format to get it back online...

any help please?

Bridge is the way to go, try a different lan adapter for the VM's.
