Multiple virtual WAN with DHCP - Is it possible?

[jonta]

Hello Forum

I would like to know if it's possible to have pfsense setup multiple virtual interfaces/IP-addresses on the WAN interface but not using static IP-addresses but DHCP.

My problem is as follows.

My pfsense is connected to a cable modem via RJ45 network cable. I have three physical interfaces in the firewall (ALIX box) WAN, LAN, DMZ.
My ISP told me that i can get 4 IP-addresses and so i want to utilize them all. Rather then buying a real computer an putting in 4 NIC's. Can i just create three more virtual interfaces that get their IP via DHCP from the cable modem?

Thank you

Any ideas?

All of those IPs (should) come in on the same interface…just set them up in pfSense as Virtual IPs per the documentation...

The problem is that they are aquired via DHCP and i do not know what the IP-address will be until i get hold of it. And there does not seem to be a DHCP-option i the VirtualIP setup.
