      @zjamali ah sorry. you can either download a backup (under backup/restore) or directly on the box with ssh do something like:

      grep -A10 pppoeha /conf/config.xml

          is it because vipref == 0? my first vhid comes with id = 0

          Yup, that cause it. i changed to VHID LAN, id != 0, its appear in log

            @zjamali great, thanks for figuring that out. I need to check why it's not working with vipref=0.

            currently i have no idea why this happens. vipref 0 is just the first item in the vips. config_get_path is a standard pfsense function.

            Maybe it is something with the way you configured that vip? is your first VIP configured differently ffrom the one you were using later?

              @perrin Its the first vip configured in both pfsense node. So it gets id = 0.

                @zjamali this is the way the dropdown in the PPPoE-HA GUI looks in my production firewall:

                2115036b-f0fa-4528-a8e0-b08059022544-grafik.png
                in my case VHID 18 is the one that is configured for failover.

                Can you check if yours maybe starts with VHID 0?

                  @perrin Mine also start with VHID 1 but if you go to Firewall -> Virtual IP, there is listing of all VIP, you hover on the edit button for first VHID, the url link will say its id=0

                  id = 0 is for internal system id for record creation whilst VHID 1 is for user POV, if i am not mistaken.

                    @zjamali yep, same here. I'll debug why it is not working on the first VIP later.
                    Can you temporarely work with a different VIP?

                        id = 0 is for internal system id for record creation whilst VHID 1 is for user POV, if i am not mistaken.

                        I tried reproducing the behaviour by removing all carp VIPs from my test firewall and adding just a single new one so it gets "id=0". In my test VM the script behaved as expected:

                        Sep 17 07:46:31 	pppoe-ha 	1464 	VHID 1 BACKUP -> DOWN wan (pppoe0)
                        Sep 17 07:46:31 	pppoe-ha 	1464 	Handle CARP command for 1@vtnet0.510 - BACKUP 
                        

                        and

                        Sep 17 07:46:35 	pppoe-ha 	52762 	VHID 1 MASTER -> UP wan (pppoe0)
                        Sep 17 07:46:35 	pppoe-ha 	52762 	Handle CARP command for 1@vtnet0.510 - MASTER 
                        

                        so, there must be some differences in the config between your and my firewall.

                        this is the Virtual IP definition in the my config XML:

                        <vip>
                        			<mode>carp</mode>
                        			<interface>opt12</interface>
                        			<vhid>1</vhid>
                        			[remaining data ommited]
                        </vip>
                        

                        so, in my case it starts with vhid = 1 instead of zero. can you confirm this in your installation?

                          The record that i having the issue is this

                          b0fb1eb6-070c-481c-bff5-e607d1f6631a-image.png

                          Check if your opt12 with vhid 1, when you hover the edit button, id = 0. that causing the trouble when selected on the mapping. If i using other carp vip, it can reconcile

                            @zjamali Yep, in my case my VHID18 is ID=0

                            but in my case this VIP also works:

                            Sep 17 08:08:42 	pppoe-ha 	41559 	VHID 18 MASTER -> UP wan (pppoe0)
                            Sep 17 08:08:42 	pppoe-ha 	41559 	Handle CARP command for 18@vtnet0.510 - MASTER
                            Sep 17 08:08:39 	pppoe-ha 	28341 	VHID 18 BACKUP -> DOWN wan (pppoe0)
                            Sep 17 08:08:39 	pppoe-ha 	28341 	Handle CARP command for 18@vtnet0.510 - BACKUP 
                            

                            Can you please confirm that your VIP correctly switches from MASTER to BACKUP?
                            Also your vhid 2 network overlaps with vhid 101 and vhid 3 with 102

                              Hmm...

                              empty($row['enabled']) || empty($row['vipref']) || empty($row['iface'])) continue;
                              $vip =
                              

                              empty($row['vipref']) will then exlude viperf=0 is not it?

                              I think this must be changed to

                              if (empty($row['enabled']) || !isset($row['vipref']) || $row['vipref'] === '' || empty($row['iface'])) continue;
                              $vip = $vips[$row['vipref']] ?? null;
                              

                              If we want to use 0 from viperf array (or any other not empty value)

                                you are right. there is a bug in the reconcile_all function.

                                i will fix that.

                                  ok, i did a complete refactor of the logic within handle_carp_change and reconcile_all so that in the end both functions use the same logic. tested it on my machine and it seems to work for me.
                                  I uploaded a new pkg version 0.1.1 to github.

                                  Happy to get feedback from your tests.

                                      If the PPPoE interface is already up and the selected VIP is MASTER, this is what I see in the logsб when pressing "run reconcile now"

                                      Overall, I can’t say it’s stable for me—I’m not sure why. I also need to fix another bug. It looks like something is preventing the VIPs from starting when the firewall boots. Thats why I used

                                       $PHP_BIN -r 'require_once "/etc/inc/interfaces.inc"; interfaces_vips_configure();'

                                        what is happening on a reconcile is that all interfaces are forced in the state they should be in. For the UP-command the script currently does a 'interface reload' (/usr/local/sbin/pfSctl -c 'interface reload <interface>'), whereas for the down it does a ifconfig <interface> down

                                        It showed up in my tests that using 'ifconfig <interface> up' as a UP-command would not reliably connect the pppoe interface in every case. That is why i opted in to use the reload command. The downside of this is in fact that it breaks the connection. I could add a check to see if the interface is already connected before reloading it to fix this behaviour in reconcile. I might be adding that.

                                        Overall, I can’t say it’s stable for me—I’m not sure why. I also need to fix another bug. It looks like something is preventing the VIPs from starting when the firewall boots.

                                        great to hear that is is stable! Regarding the VIPs not coming up: I have no idea where this is coming from, probably has nothing to do with my script. On both of my firewalls the VIPs come up as expected. But i am only using VIPs as part of CARP.

                                          Unfortunately I have to clarify: no — your variant does not work stable on my systems. The bug described above on an already loaded system with PPPoE up seems to start with initialization of your script, and the link falls into packet loss; I don’t even need to press the button. Also please look at the “Enable” checkbox, try to add several interfaces. For me it sometimes disappears at all, sometimes moves around.

                                            @w0w i created a new version 0.1.2 of the package which now checks if the state of an pppoe interface is up (ip address present). If that is true and the desired state of that interface is also up, the script will not reload the interface. so it should not break any legit connection.

                                            regarding your issue with the GUI: I can't confirm the bug. I can add as many interfaces as I want and the GUI stays consistent. I am using the pfSense rowhelper in the GUI, so that is more or less standard functionality. can you give me some more details on when that fails? also which browser are you using and do you have any plugins in use which mangle the html of a page (e.g. adblock)?
