      I entered an alternate WAN MAC address from my notebook after successfully getting DHCP from my ISP on that notebook. No IP was assigned to PfSense for the same MAC. The only thing I can see that may be an issue is that it is requesting the same old IP address via Requested-IP Option 50 in the DHCP request. For example:
      Client-Ethernet-Address 00:15:5d:00:8c:02
      Vendor-rfc1048 Extensions
      Magic Cookie 0x63825363
      DHCP-Message Option 53, length 1: Discover
      Requested-IP Option 50, length 4: (the old address I am trying to change)
      Client-ID Option 61, length 7: ether 00:15:5d:00:8c:02
      Hostname Option 12, length 7: "pfSense"
      Parameter-Request Option 55, length 10:
      Subnet-Mask, BR, Time-Zone, Classless-Static-Route
      Default-Gateway, Domain-Name, Domain-Name-Server, Hostname
      Option 119, MTU

      Sometimes the same IP is nice, but sometimes that is not what we want. How can we prevent Requested-IP Option 50 in the DHCP request?
