      If I understand your setup correctly you are trying to run pfsense as accesspoint only and you want to run your wan interface as wired interface to your real lan and the wireless interface for your wireless clients getting dhcp from a server in real lan which means pfsenses wan?

        @cmb:

        that's on xl0, which should be your WAN, to destination your LAN subnet.  You can't have DHCP coming in on WAN going to your LAN, so that's an automatically added safe guard.  that doesn't affect anything between your internal networks.

        Not even in bridged mode? Is there a way to overpass that safe guard? I really need that…

          My setup is that I have a WAN, LAN and WLAN (wireless) and if I bridge LAN and WLAN then WLAN works great except it doesn't get an IP from the DHCP. Only LAN clients get an IP, on the WLAN clients I have to setup a static IP.

          I'm downloading 0.92 right now and to see if it works on that. Otherwise I just wont bridge the two and setup two IP ranges on the DHCP because that works just as well for me  :)

            I haven't tried it yet but you should be able to have it work with a single ip range. Assign a dhcp pool of like 50 to 150 for the wired and 151 to 254 to the wireless and point  then just set an allow rule for anything from the wireless to goto anything on the lan and anything from the lan to anything on the wireless and you should be set.

              When you bridge LAN and WLAN(opt2) then the DHCP tab for WLAN isn't there any more i.e. I can only setup DHCP for the LAN.
              I havent had time to test on 0.92 yet.

                Hi,
                Have you managed to solve this problem?
                I'm now faceing the same problem  (PFS 1.0-BETA1), and looking for a solution.

                    Thank you for your answer. Probably I am misunderstanding something, but it doesn't work for me.
                    What I did: LAN 10.0.0.0/27(fxp1) I gave OPT1 10.0.0.6/27(ath0 WEP enabled).
                    Enabled DHCP server on OPT1 and assigned static reserves for clients. It doesn't work.
                    If LAN is 10.0.0.0/27 , OPT1 10.0.0.40/27 it works fine. But in this case a can't apply traffic shapeing for OPT1 :(
                    That's why I am trying to bridge the two.

                      Then you will most likely need to depend on an upstream dhcp server.

                        I think, maybe I am wrong, that the rule 303 blocks the dhcp requests, what is that? Can I switch it off somehow?

                          Turn off block private networks and the bogon option under WAN.

                            Thanks for your reply but this didn't help :(
                            Not to say that I wouldn't like to open the WAN for these kind of private networks.
                            The other question is that how comes WAN in the picture, when I bridge LAN and OPT1?
                            Anyhow I did for experience and now I receive the following blocks:

                            Dec 29 23:27:42 pf: 000078 rule 296/0(match): block in on ath0: 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request [|bootp]

                              Yes, the block on WAN is useless in this case, I misread before.

                              Let me test this out.  I'll get back to you.

                                  Oddly enough this was not working for me but after I rebooted the client, it does work.

                                  Not sure why you're having trouble, it works here.

                                          That works as well.  I have both configurations here that I can restore.

                                          Just restored a similar config and its fine.

                                            That's good, in this case I've got hope to set it up finally  :)
                                            But now I've got two lines repeated on the diag_logs_filter page:

                                            Dec 30 21:54:50 pf: 000056 rule 141/0(match): block in on ath0: 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request [|bootp]

                                            I have rules allow everything from OPT1 to LAN and vice versa.
