Pfsense box behind Touchstone Data Gateway DG1670



  • Hello guys,

    I have pfsense box with three interfaces for WAN, LAN, and OPT. I also have static IP address.
    I can't figure out how to setup pfsense box behind Touchstone Data Gateway DG1670. I just got this modem while upgraded my high speed internet plan recently. Before, I used to have old cable modem with coax input and WAN input. Those days, I just connected WAN input from cable modem into WAN interface in pfsense box, configured all three interfaces, and everything was working great. Now, the Touchstone has coax input and four LAN inputs. It doesnt have WAN input. So, I am confused about how can I utilize those LAN inputs and WAN interface in pfsense box. Basically I want continue to have WAN, LAN and OPT (for DMZ) managed by pfsense. Does anyone have any experience with Touchstone Data Gateway DG1670, or can someone please suggest any proper direction? Thanks in advance.
