      @chudak It's an APIPA address.

        Thx
        So is it indicative of DHCP problem ?

          @chudak Not necessarily. It may be that the Apple device in question assumes that address and makes some announcements before acquiring a real address from your DHCP server. Just a guess. Are you having any problems with DHCP in general?

                  All of the sudden I started getting emails from pfsense like this: ...
                  ip address: 169.254.178.43

                  I guess it is related to IPv4 link-local (169.254.x.x) gateway does not function
                  With 2.5.1 intermittently my laptop doesn't get a valid IP address, instead getting one from 169.254.x.x which in not in my LAN IP address range.

                    Not 'getting'.
                    Self-assigning.
                    Because it could find a DHCP server that would give it a DHCP lease, or, nuance, it got a lease that it wouldn't accept.

                    Routing to the Internet won't work of course.

                    No "help me" PM's please. Use the forum, the community will thank you.
                    Edit : and where are the logs ??

                      Those 169.254 addresses indicate a DHCP problem, not gateway. The DHCP client will revert to one of those addresses when a DHCP address isn't available.

                      I haven't lost my mind. It's around here...somewhere...

                        how troubleshoot it ?

                          One thing you can do is packet capture to see what's happening. Also, is it just one device that gets that address? Or all? If all, then it's likely the DHCP server. If just one, then the problem is with that device.

                          Run Packet Capture on the LAN interface and filter or DHCP. Then connect that device and see what turns up.

                            Based on MAC it's my iPhone and it does not happen on all devices and too often.

                            Thx

                              When you capture an occasion when it fails, do you see anything from the DHCP server? However, if it only happens with that phone and only occasionally, it's likely a phone problem, not pfsense. Is it an older phone? Is it one of those that slows down when the battery doesn't hold a charge as well?

                                    emails from pfsense

                                    It's an email? That implies something in pfSense is triggering an alert that is sending you a notification email. What is in the logs at that time?

                                    By itself the text shown seems rather meaningless...as noted an APIPA address is self-assigned by the default when DHCP isn't functioning. But then why would pfSense even know about the IP in a subnet that's not its own? And what is the alert that is triggering...there is no alert or error as written? What is the email subject?

                                    re: Private Address, that is for creating a unique MAC address not IP address.

                                    Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                                    When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.
