Posted on 2011-10-25
Last Modified: 2012-05-12
I am setting up a test environment.
I have a single Host ESXi 5 on our company network.
I want to setup several Guests inclusing AD, DNS/DHCP. I want to completely separate it from the Company Network.
I want my Guests VMs to access ONLY internet via the Host. No DHCP, DNS, AD

How can I setup my ESXi 5 environment so that my Guest VMs ONLY has internet access via the ESXi 5 Host?
Thank you,

    If it can access your network then that is a problem.

    I would suggest creating a pfsense VM firewall and connecting the private side of pfsense to a vSwitch that has not physical interfaces.

    Now all traffic among the vm's is firewalle from your LAN but you can still access vsphere.

    You could configure a dedicated vSwitch with a primary NIC uplinked to your Internet feed.

    You would then allocate and create a Virtual Machine Portgroup on the Virtual Switch, and use that Virtual Machine portgroup to connect your Virtual Machines, they would then have access to the Internet, but be excluded from the rest of your LAN.
