      @stephenw10 thats funny actually I didn't recall that thread at all ;) But this is really just a rehash of that thread ;) and I had suggested doing what you had said about pool to none, and set reservations for those that want a gateway..

        Tried it out on an old iPad. Still getting a GW, but it may need a more aggressive approach to get past Apple being helpful.
        I like the approach and will try the same trick to not give DNS servers to the cameras.

        Thank you for searching better than I did...

          Maybe the value type there should be IP address. 🤔

            @andyrh ok just tried this on my windows pc.

            So I set it to dhcp, got a lease with gateway per dhcp scope, etc

            Then set up a reservation for 192.168.9.66, and set option 3 with nothing.. and released and renewed and got the .66 address, but no gateway..

                @stephenw10 yeah that seems to be a good option for sure when you don't want a client to have a gateway. I think that should work for @AndyRH

                  Something went wrong around 13:50 and DHCP became corrupted. Had to restore it. (remember kids, backups are for fun, restores are serious)

                  I have a new weekend project...

                  Lots of 89884 messages then a crash. A restart did not work so I went to the backup.

                  Jan 3 13:59:06 dhcpd 89884 /etc/dhcpd.conf line 579: unexpected end of file
                  Jan 3 13:59:06 dhcpd 89884 ^
                  Jan 3 13:59:06 dhcpd 89884 }
                  Jan 3 13:59:06 dhcpd 89884 /etc/dhcpd.conf line 577: semicolon expected.

                    Hmm, just by adding the option value to a static mapping?

                      @stephenw10 That is my guess. I will test it this weekend.

                        I finally got back to this. I was not able to reproduce the problem. It is now working as expected.

                          Just in case someone wonders by...
                          If the DHCP scope has a GW value of "none", if you do not specify a GW in a static mapping the host will not get a GW.

                            Ah, yes that would do it. The static values override whatever is in the main config. So leaving it empty there would not override 'none' set in the main config.
