      I have set-up my pfSense box to have 2 WAN Connections as in the above picture. My main WAN for most of my network, and a separate DMZWAN for a non-fire-walled network that I have just my gaming consoles on until my ISP implements IPV6.

      I have made the connections through my switch as I can receive multiple public IP's and would like to direct the connection at my leisure.

      My WAN interface works without issue, the problem is with the DMZWAN interface never seems to get an IP address assigned. If I connect the pfSense box directly to the modem, both interfaces get IP's assigned and there is no issue.

      Once the connections go through the switch only the WAN interface receives an IP address, and i do not know why. Everything should be separated by the VLANS I have setup, ans WAN works without issue this way.

      Why does my DMZWAN interface not get an IP assigned?

      SOLUTION EDIT: I discovered that STP ( Spanning Tree Protocol) on the switch was disabling the port 14 as it was connected to a device(The Modem) with the same MAC address as port 13(Although there are 4 ports on the modem, they all have the same MAC address as it's a modem/router that I have set to bridged mode). Disabling STP on the 2 switch ports (13 & 14) allowed both interfaces to pull IP's from the ISP and everything in working now :)
