Doubts with NAT scenario

  • Hi, I have a question about how to configure pfSense. My goal is to monitor the bandwidth consumed by computers and smartphones connected to the LAN.

    Scenario 1 - The scenario with virtual machines that works:
    Two virtual machines in internal network, with a network card. (Windows 10)
    A virtual machine with two cards, one in an internal network and another in a bridge. (PfSense)
    A router with DHCP enabled.

    The router facilitates the ip to the bridge network card of pfSense and pfSense facilitates its own DHCP IPs to the two computers by internal network. In this case all the traffic goes through pfSense.

    Scenario 2 - Scenario that I have doubts how to configure:
    A physical machine that also runs the pfSense virtual machine. (Windows 10 and VMware)
    Two virtual machines in bridge, with a network card. (Windows 10)
    A virtual machine with two cards, the two bridge network cards. (PfSense)
    A router with DHCP enabled.

    My doubts are, in the second scenario would I have to disable the DHCP of the router, because it conflicts with DHCP of pfSense? How do I create an access point so that the clients for wifi are behind pfSense, if the router is that has the access point? Is there any way to leave the router behind pfSense without using DMZ? If I make a DMZ, would I need a public IP or would I have to configure pfsense as a router? If I configure pfSense as router the previous router no longer works for me?

    I'm sorry if you did not understand something I'm using the google translator, I'm a computer student.
