The next step is: how to make the virtual environment accessible from the outside? The public IP that has been provided to us is assigned to the ESXi management VMkernel.
What was desired was to install a firewall on a VM, for example, pfSense, and assign a public IP to its WAN interface.
Therefore, it is necessary to purchase another public IP, which fortunately OVH offers at only 1.5 euros per month. Once this is obtained, a setup needs to be performed both on the OVH control panel and on the virtual network card assigned to our pfSense.
First of all, the firewall VM must be deployed and, when ready, shut down. Then, from the OVH control panel in the Network->IP section, a new virtual MAC needs to be generated.
The process is very simple, click on the three dots and start the wizard; you only have to choose “vmware” as the desired type. This will create a random MAC that starts with the classic 00:50:56.
Having obtained this, it must be manually set on the virtual WAN network card of the firewall.
After restarting it, traffic directed to the additional IP will be forwarded to the same vSwitch where we have the Management, with the recipient MAC equal to the one just created.
