Virtual IP's From WAN with DHCP

[Soloam]

Hello, my ISP provides more that one IP to be used, but it's assigned by DHCP. I only have 2 ports on my PFSense, so I can't connect more that one cable to WAN. On the ISP side, the Web is assign to VLAN12, so on the WAN port I receive VLAN12 and the PFsense make a DHCP request, that assigns my public IP. My idea was to create a virtual IP Interface that would make also a DHCP request and receive a new IP.

From my research on the forum, this is not possible, so my question is, if this is really a limitation or if its not possible because it's not implemented.

Is there any way to bypass this with only one WAN port?

Thank you all

The underlying software doesn't support that. You'd have to use two NICs.
