      Hey everybdy,

      i´m new to pfsense so maybe the answer to my question is pretty simple.

      I´m trying to setup pfsense as a captive portal behind my actual firewall until we´ll replace the old FW with the pfsense.

      For that i´d like to relay dhcp requests sent to the optional interface to the dhcp server from the wan interface (my firewall)

      So i enabled dhcp relay on optional and entered the IP of the DHCP Server of my firewall.
      I can ping that ip from the pfsense so general communication is given.

      Under the dcp relay theres the following info:
      "Select "Proxy requests to DHCP server on WAN subnet" to relay DHCP packets to the server that was used on the WAN interface. "

      what is pretty much what i´m trying to do

      BUT

      i can´t find this option anywhere, it´s not under the dhcp relay options.

      Do you guys know where to find that option?

        i also added 2 firewall rules

        • interface WAN allow ANY
        • Interface OPT allow ANY

        but its still not working, the firewall log doesnt show any blocked packages (after i added these rules)

          where is that info your reading about wan and dhcp relay?

          Also why would you do such a thing? Are you not natting and just routing/firewall?

          This is a temp setup - why would you not just allow pfsense to hand out dhcp for its lan segment.. It by default nats its lan to wan - so does not really matter what IPs the boxes on the lan side of pfsense use.  Especially if this is just a temp setup.
