My current internet setup is that I have a Motorola Surfboard cable modem WAN port connected to my pfSense PC WAN port. The LAN port on my pfSense PC is then connected to one of the LAN ports on my 48 port network switch. The network switch connects all my PCs in my house (LAN). The IP address of the cable modem is 192.168.100.1. The IP address from the ISP is a dynamic IP address. The IP address of the pfSense PC is 192.168.1.1. and it serves as my DHCP server. Everything is working fine with this setup.
Now I want to introduce the HD2 router in this setup. So I setup the HD2 router between my cable modem and the pfSense PC and it is not working. It is not passing traffic from the cable modem to the pfSense box. I changed the IP address of the HD2 router to 192.168.1.249. All the other settings on the HD2 router are set to default. To be clear on how the HD2 is setup, the Motorola Surfboard cable modem WAN port is connected to the WAN 1 port on the HD2, and the LAN 1 port of the HD2 is connected to the WAN port on the pfSense PC. The LAN port on my pfSense PC is then connected to one of the LAN ports on my 48 port network switch.

Existing setup
Users (192.168.1.x) —> (192.168.1.1, LAN) pfSense (WAN - public IP assigned by ISP, 24.125.xx.xxx) —> (192.168.1.249, LAN) HD2 (WAN, **192.168.100.x? - Not sure? **) —> (192.168.100.1, WAN? - Not sure if WAN or LAN - This is the IP address I use to access the configuration page of the modem.

pfSense LAN IP is 192.168.1.1. The pfSense box is setup as a DHCP server and serves out IP addresses to the individual PCs on the LAN from the range of 192.168.1.1 - 192.168.1.254.
pfSense WAN IP is dynamic. I do not have a static WAN IP address assigned to me by my ISP. For example, currently the public dynamic WAN IP address assigned to me by ISP is 24.125.xx.xxx.
HD2 IP address is 192.168.1.249
HD2 WAN IP? Unknown
Motorola modem IP address is 192.168.100.1. This is the IP address I use to access the Configuration page of the modem. This is the default Ethernet IP Address of the modem. There is only 1 port on the Motorola modem and it is labeled WAN.
Change the pfSense WAN setting from DHCP to static. Assign a static IP address to the pfSense WAN connection to be in the IP range of the HD2 (i.e 192.168.50.2). In pfSense add a WAN gateway and assign it the IP address of the HD2 (i.e. 192.168.50.1).
