    Well it sure looks like the box is declining the .26 address.  Why would it do that unless it believes there is something else on the .26?

    If you say it accepts .29 โ€“ why not just change your reservation for it to be on .29?

      Try to assign 0.26 to something that would give you more verbose DHCP logging output - like another pfSense box/vm, a linux box, etc.

      If it also rejects 0.26 you'd at least get a better answer about why.

        there is nothing else on 0.26 because all devices r on dhcp, no static ip assigned to any devoce at all and nor does pfsense show it giving it out to any device because the pool starts and ends in a different range. all my deivces have static mapping in pfsense so there isnt anything magically conencting to it by any chance. i can always just use the 0.29 but if its a bug it needs to be traced and fixed, also if there is any other deivce with same ip then the dhcp gives a different message i guess, like not available or so which i guess any1 can try it out.

        ill try to assign 0.26 to some other device and see what the logs show

          It is not a bug on pfSense. If it is a bug, it's a bug on the DHCP client, not pfSense.

          pfSense can't make a client tell pfSense to reject an IP - the client is generating that response - not the firewall. There is nothing to "trace" or fix.

            i just assigned the same 0.26 to a grandstream voip phone and it seems pfsense gave it out just fine this time and the phone was able to call out also without issues but as soon as i switch my ipad to 0.26, its the same old declining message.

            also tried overlapping devices with same ip and it seems dhcpd says unavailable as message but not "not found"

              There you have it thenโ€ฆ it's a problem with the iPad DHCP client somehow. Why, it's difficult/impossible to say, but it's the client for sure.

                      Clearly a strange issue to be sure, do you have a different ipad you could try an assign the .26 too?  is it some weird bug in the OS or the dhcpclient on the devices or something specific on that device.  Could it at one time been assigned .26 as static or from some other dhcp server and now it is rejecting that?

                              so did you give it .26 before when it was on the netgear network?

                              Maybe if it got .26 from different dhcp server is why it declines .26 from this dhcp server?

                                on netgear it didnt assign any static map, the router used to handle automatically and i guess the range on that was 192.168.1.2-254 and i use 192.168.0.1 as pfsense same subnet

                                  Very strange - but as stated its not something related to pfsense, pfsense is clearly making the offer and your client says no for some reason..  Would need to look on that device dhcpclient log to why it declines it.

                                    Reset the network settings on the iPad and see if that helps. Maybe the iPad has been on another network and had the 0.26 address there. Just guessing ;)
