I'm working on creating a lab environmenton VMware ESXi 6.0 for firewalls VMs and networking features. so one of our steps is to simulate the firewall like in real environment. So I have at least 2 virtual interfaces for the firewall one for wan and for lan . But what i nerd to simulate is that like in real world tou get real public ip address to access internet. but in my case i will assign on virtual WAN interface i will assgin random public ip like : 207.365.35.124/29 but i need to nat this random public ip to local ip of the host so it can access the internet through the local of the host (ESXi) server. Please click on the link to see the image to clarify the point in other words : I know how to traditional nat local ip to public ip to access the internet , but what I need to do is the opposite which is nat public ip assigned to virtual interface and nat it to local ip of the uplink of the phsyical NIC of THE ESXi. Maybe i need to use internal VM as a router or something.
