DMZ Questions (pfSense vs. DD-WRT)


  • Hello,

    I've been running DD-WRT on my linksys router for a couple years now, but I've started playing with pfSense and would like to move way from DD-WRT. My issue is DMZ. I have a router provided by the company I work for and it currently sits behind my DD-WRT router with the DMZ set to it's IP address that DD-WRT assigned (see attached 'DD-WRT_settings-DMZ.PNG').

    I've been reading forums and hot-to articles all weekend, but can't get my work provided router any internet connection. I have no control over the settings on the router provided by work.








  • Plug another client into DMZ and confirm that it gets an address from DHCP like 192.168.14.100… and can access internet. Then you know the basics are working, which they should be based on your screen shots.
    Next look on the company device and see if its WAN is getting DHCP in 192.168.14.* - that should also be seen in pfSense Status->DHCP Leases. If so then it should be able to see out to the internet. But maybe it has the address 192.168.13.149 fixed in its WAN, like in your DD-WRT screen shot. If so, then you need to use 192.168.13.0/24 subnet for your DMZ.

    If you need incoming connections from the company to your device then you will need to do some port forwarding on pfSense, or1:1 NAT to forward your whole WAN to the company device.


  • I'm not having any luck yet, but I can only work on this in spurts.

    In the mean time can I run the pfsense box behind my DD-WRT router?
