Interfaces, two Static IPs, and NAT
Static IP#1: 18.104.22.168 –> FreeBSD pfSense Server
Static IP#2: 22.214.171.124 –> Linux Server
ISP requires MacID of devices being assigned a static IP. The first one is easy – 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.
