I need to construct a NAT for certain machines within the network. Wish to do this with dvSwitch - as it seems the logical way of attacking the problem as in this scenario there's just under 30 hosts.

In order for the NAT'ed VM's to have access to the 'real' network. I am providing a 'router' VM, which will have access to the WAN/outside network, and also act as the DHCP server for the NAT'ed machines.

Problem Space

When the machines connected to the NAT interface and the router are on the same host, then they get an IP from the router VM, and work perfectly (routed outside).

Unfortunately machines on other Hosts that are connected to the dvSwitch do not get an IP and further tcpdump shows no network data getting through across the hosts within the dvSwitch.

Has anyone achieved a NAT solution using a dvSwitch before that they could share?!

Thank you.
