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.
What am I doing wrong? Need help.
