Problem with pppoe over vlan

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...Steve

OK, understood!
Thanks anyway!

BTW: I set up a identical machine (APU2C0) with a fresh pfsense 2.4.5-RELEASE-p1 with no other packages and the behavior is exactly like my productive pfsense. Saving the LAN(igb0) or the WIFI(ath0_wlan0) interface without any changes made, make the vlan to be remade! (Vlan is on igb1). Anyway seems I have to live with it
-
Hmm, wondering if it's because of the bridge maybe... Though without igb1 in the bridge you would not expect that to hit WAN...

igb1 is not in the bridge. The bridge is between LAN (igb0) and WIFI (ath0_wlan0). igb1 has no interface assign on it (only the vdsl-modem is connected to it) and is only parent for vlan7 and pppoe connects via vlan7.

Yes, exactly. Without igb1 in the bridge I wouldn't expect to see changes made to the wifi interface affect it.
But I'm unable to replicate it. The interfaces do not lose link and come back up when you make a change. Even on the interface you apply the change to.
You must have something in your config that is applying a setting to all interfaces everytime they are reloaded. Like maybe putting them in promiscuous mode for monitoring. I could imagien iftop or snort doing that. I did test Snort though.Anyway this is not a problem with PPPoE over VLANs, not specifically at least. The VLAN is being rebuilt here because the parent interface is flapping.

This is maybe an explication for my "productivity" pfsense but not for the clean install pfsense on the the secondary machine - there is no snort or anything else like that.
In the mean time I get a vdsl-modem who is setting the tag 7 (neccessary for getting a connection on my provider) so I dont need the pfsense vlan7 anymore. Now I can store any interface without loosing connection! (but the vlan7 gets still renewed every time - I didnt deleted the vlan7 because I will observe in the future whats going on with it) So this is my personal "workaround".
Maybe you cannot reproduce the situation because of running pfsense in a VM? Just a supposition ...

No, I've tested a number of different hardware devices too. No insight at this point.

That let me "speechless" - as you can imagine I crushed my head long time before writing in the forum because I dont want to steal the time from nobody, with a problem that I can solve myself, but I did not find a hook from where the problem may be get solved.

Try just doing a basic install and testing this. Add the parts of you config one at a time until the issue shows up.

Thats what I have done on the secondary machine - just basic setup and the vlan7 problem was there.
-
Was it dropping the link on the parent NIC without the VLAN on there? Just a basic WAN and LAN config? And that wasn't on an APU?

The parent link wasnt dropped. Only the vlan was renewed. Yes only Lan and Wan. It was a identic APU like my productive system (APU2C0)
-
Ah, that's a different problem then! Yes, the VLAN should not be regenerated if the parent is not dropped/reconfigured.
Reviewing here it looks like your other test system was also an APU and also had a wifi card. Was it also bridged? But, to be clear, on that other system you don't see the links go down like you do on the original system?

You will be laughning - since I switched the Wan from vlan7 to igb1 and let the modem do the tag 7 neither the productive system is dropping the links - only the vlan gets renewed ... its weird ...
-
Hmm, so even though you no longer have vlan7 assigned it still gets rebuilt when config changes are made?

YES! (I checked a few times on both machines)
