I’ve set up a virtual server running VMWare ESXi with four Virtual Machines (VMs) running in it. Any one of these VMs has a unique IP and are running fine. Two of these are ZS VMs providing DNS the other two are Windows VMs running a webserver and a e-mail server.
Like i said everything is running fine but i want to strengthen the windows VMs with a firewall and i think it might be done with one (or the two) ZS VMs. For that i have an internal virtual network between the four VMs.
The problem is that i don’t have the skills to do this. Can anyone help?
Here’s a simple diagram:
I want to keep the current connections (green lines), and protect the Windows VM’s (currently connected with the dotted pink lines) and maybe connected then to the ZS VMs trough the internal virtual network behind the ZSs firewalls (orange lines).
Don’t know if this will work, because IIS and the mailserver need to be visible from the internet and with their unique IP for obvious reasons.
