      Static IP#1: 1.1.1.5 โ€“> FreeBSD pfSense Server
      Static IP#2: 1.1.1.6 โ€“> Linux Server
      Subnet: 255.255.255.0
      Gateway: 1.1.1.1

      ISP requires MacID of devices being assigned a static IP. The first one is easy โ€“ it's the MacID to fxp0. The second one, would the MacID be for em0 or eth0, or would it still be fxp0?

      What do I do or how to I go about adding this under NAT 1:1? What values would I need to enter in?

      EDIT: I realize the alternative could be putting a switch behind the modem, and connecting both "WAN" ports to the switch. I just want to know how it could be done through NAT 1:1.

        If you hardcode your IPs as static, you could add a CARP type VIP on WAN, that will have a unique MAC address that your cable provider could use.

        Though if you need two IPs both obtained via DHCP, that is a bit trickier and you may end up having to do as you say and plug two interfaces into a switch. Not ideal, but IIRC that has worked for others.
