      I tried to execute the command from the webconfigurator via the command prompt tab, but it just returned the same input. I will try later today when I get access to the actual box.  To enable DHCP for OPT1, I checked the "Enable DHCP server on OPT1 interface" in the DHCP server tab.

      Surely there has to be a "how to" on how to enable dhcp and dns for another lan.  It's weird that people haven't run into this before.  I assume this is a common task when using this product.  Thanks for your help.

            Did you notice the OPT1 interface statistics in the screenshots you posted?

            If something is really sending DHCP requests to OPT1 then the interface statistics should show non-zero counts for bytes received and packets received.

            The OPT1 interface status is UP suggesting it is connected to something that is proving carrier, but no data is arriving!

              OPT1 doesn't appear to have auto-negotiated its speed and duplex either from the looks of his second screenshot.  Speed and Duplex appears to be missing from his OPT1 interface page as well.

                  This still isn't working.  Can anyone provide a example rule set for how they have separate interfaces using dhcp and dns from pfsense?  I can't imagine this is an unusual request.  I am basically at a loss with this one.

                    This still isn't working.

                    What have you done to address the connectivity problem discussed earlier?

                    Meddling with firewall rules won't do any good UNTIL you get data to arrive in pfSense over the interface.

                        It's working! I installed a new nic in the PCI slot.  I was using the onboard MB nic before for opt1.  apparently it was crap.  Thank you for all your assistance on helping me figure out it was a hardware issue.
