      Do I understand correctly that IP addresses are assigned dynamically (DHCP) ?
      Is there no pause during boot time when configuring the WAN interface ?

      Open file / diagnostics / edit file
      /var / log / system.log
      during the boot, it will display approximately the following text:

      What does that look like to you ?
      I have a suspicion that em0 does not receive an ip address at the boot
      in your log line /rc.newwanip: rc.newwanip: on (IP address: ) (interface: WAN[wan]) (real interface: em0) - does not contain IP address ( it is not)
      And more
      written anything in files
      /tmp/em0_error_output
      /tmp/em0_output

      You can try to do so ( this is theory , I never did )
      https://www.freebsd.org/doc/handbook/network-dhcp.html
      open the /etc/defaults/rc.conf
      and add this line to the beginning of the file
      ifconfig_em0="SYNCDHCP"
      save the file and reboot

      if this does not help , you can try to put the boot script to pause (5 seconds) after starting dhclient. ( this is theory , I never did )

          This error
          indicates that the system is trying to add a route to a non-existent gateway
          Need to think

            Default gateway setting as default

            I have a suspicion that here a problem that at the time of loading not all interfaces received ip addresses yet.
            Can you show the group settings ?

                I'm not sure
                It is very difficult to understand someone else's code
                Can you show the group settings ?

                      The problem is solved
                      The problem is that when a script processes a group of interfaces, the system does not yet have default gateway information. To do this, check the status of the variable in the script
                      "currentdefaultgwip" (file /etc/inc/gwlb.inc)
                      I added one line for debugging
                      log_error("Point1 ip is: $currentdefaultgwip");
                      and replaced one line to check the variable ( this line is the same as above - post Rico )
                      if (($gwgroupitem['gwip'] == $currentdefaultgwip) && (!empty($currentdefaultgwip))) {

                      this is what this part of the code looks like

                      0_1547850168428_f43c6e8e-98b9-491c-9840-93219c86fbc0-image.png

                      Jan 19 01:01:57 php-cgi rc.bootup: Point1 ip is: 192.168.1.1

                      and everything works fine

                      There is another way to solve this problem ,but it is not quite correct
                      When you restart, all temporary files are deleted, if you disable the delete option, then you also do not have problems when you reboot .

                          if there are problems , write in PM
                          and send me a log in the mail
                          be sure to put the control points
                          they make it easier to localize the problem

                            and most importantly , before you make changes to the file, make a copy of it . Otherwise , in case of an error, the system will not boot and will have to fix the error for a long time

                              if you make wan_dhcp2-tier1 and wan_dhcp-tier2
                              the log will already look like this

                                @konstanti No luck unfortunately. Still doesn't work. I need to Disable -> Enable the WAN.

                                    Hey
                                    Having carefully studied this log, the only explanation of what is happening is that the boot process is happening with a slow read/write device (usb key) . Thus, the script to get the ip address does not have time to create the em0_router file in the /tmp directory. Because of this, there are problems with the initialization of the routing table .

                                    At the moment, I propose such a solution

                                    Prevent deleting temporary files on reboot .

                                    Another option is to make additional changes to gwlb.inc (but this need to test and inspect )

                                      Are we still talking about the topic here which is No default route after reboot using Gateway Groups? ☺

                                        I'm sorry this is being discussed here.
                                        Just in the case of amorphous necessary
                                        1 make changes to the gwlb file.inc ( solved)
                                        2 solve the problem of slow usb key

                                          Thanks for all your help so far.

                                            @Rico Is this fix for IPv4 only? Or should this also work for a default IPv6 gateway group. Thanks.
