      Why are you running a captive portal on a wired network? Curious..

        I was assigned to customize a CP for our business, but my boss doesn't want to install a wifi card on the router. I think eventually the device will wirelessly connect to a switch and that switch will be wired to the router.

          Ah ok - that makes sense ;)

          right about our speculation then the dhcp server just stopped working for whatever reason

          So did it stop, simple enough to see if its running on the router..

            Currently everything is working right now, I'll have to try to reproduce the error since it's kind of inconsistent, I'll update this post again if anything happens. Thanks again for everyone's inputs, they really helped.

              That's not how it works...

              You add wireless access points around your building or campus, wire those access points into the switch(es), and then the switch(es) is/are wired into pfsense/router.

                Sorry for the super late update, I was starting to think the problem is fixed since it's been a week but it popped up again this morning. It SEEMS like the dhcp server just decided to stop working. My laptop is sending ARP request who-has 192.168.1.1 but on my pfsense box the lan interface never received the arp request. I'm using tcpdump -i ue0 to check these packets. From what I know since my laptop's arp request is never answered it does not know where 196.168.1.1 is and thus no connection. Is this still related to DHCP or a problem with pfsense ignoring arp for some reason?

                  If your not getting back answer to arp, then there is connectivity issue. No that would have nothing to do with dhcp.

                  Not going to ignore arp.. Unless it doesn't have that IP anymore.

                  When you say laptop - its wireless? If you are sending arp, and the pfsense doesn't see this arp.. Then no it can never answer.

                    the laptop is connected to the pfsense box via a usb to ethernet adapter. I've tried different cables but no dice. Though I'm curious as to why restarting pfsense would make it work again.

                    Edit: I forgot to mention one detail is that dhcp is on LAN interface.

                        Yup, I remembered now I was showing a technician how to install a production version of our pfsense onto a generic build. He resetted to factory default first and changed the interfaces so WAN was on a usb port. At the time I didn't think too much about it but it turns out to be a big head for me. @johnpoz I would so buy you a case of beer if I can.

                        Thanks everyone for the inputs, I believe this is now solved.
