Wan additional Virtual interface, Both DHCP

[bruor]

I use an ISP that will give out multiple IP addresses but only via DHCP.  I would like to know if it is possible now, or possibly in 1.3 to create virtual interfaces on top of a physical interface which would then be used/treated as a secondary wan.

The need for this comes from my desire to run an asterisk server on my home network.  the port ranges for sip overlap those of my primus sip gateway which i would like to place on its own Nat-ted public IP address.

It's not possible with pfSense.
But you can put multipe cheap router in front of pfSense so they handle the DHCP stuff and forward their traffic to the pfSense which handles the multiWAN-stuff.
