      Hmm, is it any change to any other interface that triggers it?

        Hmm, is it any change to any other interface that triggers it?

        Yes, I made a test now, only saving the LAN Settings (without changing anything) and I had the same behaviour and this also:

        Aug 17 18:22:39	ppp		[wan_link0] can't remove hook mpd72282-0 from node "[13]:": No such file or directory
        Aug 17 18:22:39	ppp		[wan_link0] PPPoE: can't connect "[13]:"->"mpd72282-0" and "[6fa]:"->"left": No such file or directory
        

        and here (from dmesg) in order of actions:

        1. I save the lan settings:

        igb0: link state changed to DOWN
        igb0: link state changed to UP

        1. after that came this:
          vlan0: changing name to 'igb1.7'

        2. I hit the Connect Button (without hitting the Button the connection dont get back) in interfaces:
          ng0: changing name to 'pppoe0'

        3. and internet connection came back.

          Hmm, I can't replicate that. Though interestingly the box I'm testing on (my home edge device) has all its interfaces, including pppoe, as VLANs on the same lagg0 parent. You might expect it to force a vlan reload in the situation but it does not....

            Its strange because I have nothing special here and i have not made any change to the pfsense Installation - its a simply firewall-router with a few packages (see signature). The vlan7 on the pppoe is required by the Internet-Provider.
            Hmmmm

            PS. Until a few weeks I have used my pfsense without vlan7 thats why the problem had not occured in the past (I suppose).

            PPS. I have now, made an extra check of the patch pppoe-patch
            and it confirms that the patch is allready on the system.

              On other test systems where I have VLANs on different parent interfaces they are not rebuilt:

              Aug 18 14:10:46 	check_reload_status 	425 	Syncing firewall
              Aug 18 14:10:53 	check_reload_status 	425 	Restarting ipsec tunnels
              Aug 18 14:10:56 	check_reload_status 	425 	updating dyndns lan
              Aug 18 14:10:58 	check_reload_status 	425 	Reloading filter 
              

              That's resaving LAN with no changes.....

              Either not all that patch code is in your system somehow or you config is triggering the VLAN rebuild with something. Hmm

                Hi Steve, would you mind to send me your interfaces.inc and interfaces.php? Thanks a lot!

                  Hmm, one thing I notice here is that the igb0 link goes down when you saved that. That would not normally happen if you save an interface without changing anything.
                  I assume igb0 is your LAN there? What settings do you have on that interface?

                    Look:

                    I also downloaded the original files from github

                    https://github.com/pfsense/pfsense/blob/RELENG_2_4_5/src/etc/inc/interfaces.inc

                    https://github.com/pfsense/pfsense/blob/RELENG_2_4_5/src/usr/local/www/interfaces.php

                    and have compared with mine and they are identical.

                      Do you have Snort or Suricata running? That can cause interfaces to reconnect sometimes. In in-line mode perhaps.

                      If you assign/enable igb1 does that also go down/up when you resave LAN?

                        Yes, i have Snort but not in in-line mode.

                        igb1 is assigned to vlan7 and to pppoe ...

                        Steve

                        PS. Its only the vlan that get renewed, igb1 is left untouched.
                        In conclusion - when settings are applied (in my case) on LAN (igb0) or WiFi (ath0_wlan0) only the vlan gets affected! (When applying settings on LAN (igb0) its normal that igb0 go down/up)

                          Right, but I'm saying if you assign igb1 as a new interface and enable it with no config but just so it's up does that also go down when you make a change. That would explain why the vlan is rebuilt, but not why igb1 goes down.

                            Yes it also goes down, here the dmesg output:

                            igb1: link state changed to DOWN
                            igb1.7: link state changed to DOWN
                            igb1: link state changed to UP
                            igb1.7: link state changed to UP
                            vlan0: changing name to 'igb1.7'

                            PS. Maybe its helpful to know that my system was continuously updatet from 2.4.3 (I'm using pfsense longer but 2.4.3 was a fresh install with config recovery)

                            PPS. Another Idea: Snort needs interfaces in promiscuous mode - could that be a possible culprit?

                              Mmm, exactly Snort applies promiscuous mode when it starts.

                              What happens if you just restart Snort?

                              What interfaces do you have Snort running on?

                              It looks like the VLAN here is correctly being recreated because the parent interface is brought down. That's why I can't replicate it here. I'll try with Snort....

                                Snort restarts without any issue.

                                    I crashed myself my head - I have no clou where to set the axe ... definitiv clear is that every time I save a interface (without any changes) (LAN or WIFI or the OPT2 igb1-temporary created) the vlan gets remade ... and that kills the pppoe!

                                      Yup. I see it it happening for you I just can't re-create it here...yet.

                                            No I've been unable to replicate it. Something you have set there is causing the NIC to flap and I'm not sure what.
                                            We might need to review your config somehow...
