Setting up a network for VM guests

view story

http://serverfault.com – I have 4 windows VMs and a Mikrotik router vm as guest on an ESXI 5 host server. I want to set up a network so that i can assign private IPs on the windows VM and make the Mikrotik router VM their default gateway. I know how to create a virtual switch for the physical NICs on the ESXI host. How do I create a network of the VMs where the windows VMs will sit behind the Mikrotik router. (HowTos)
