pfsense 2.4.4 fails all pppoe's after disabling one

Hmm, I am seeing this now although I did not initially after upgrading. My PPPoE interfaces usually stay up for months.

What exactly did you do to trigger this?

I just click “save” on my LAN interface, then click apply. Don’t even have to change any settings.

Yes, going to interfaces > connect fixes it, but what if you need to make a change on a remote pfsense.

netblues

I can confirm that this is exactly the case. Hitting reconnect brings it back.
However, on a system with multiple ppp connections, vpn over them etc, a simple change somewhere brings down many things. And obviously, if you are remote, over ppp, things get very very serious.
And bye bye to ppp interfaces staying up for months too :(
It doesn't matter the nic make, if it is physical or virtual, it happens over all.
What hits me is how few people are using ppp over vlans.
Can we expect a ticket? A quick fix?

albert_lightware

Another trouble I found is one ppoe connection type won't even reconnect if I just reboot or press connect button on interfaces menu.
I have to rebuild the connection to get connectivity.
Remove the pppoe config, remove the vlan interface config and create again the vlan for the interface, and the pppoe settings.
In my case is Vodafone Spain, vlan 100 and ppoe session over the vlan100.

I think there are some issues with the vlans and pppoe, they have to investigate that on this release 2.4.4 this wasn't affecting previous versions.

I opened a bug to track this. https://redmine.pfsense.org/issues/9148

When you see this do you also see logged:

Nov 21 16:45:21 pfsense kernel: vlan1: changing name to 'lagg0.102'

Or similar?

I actually see the connection come back up successfully in the system log and then fail. I think think this is actually a symptom of something else.

netblues

@stephenw10 indeed.. this is in system log

Nov 22 05:36:26 lb kernel: vlan2: changinn name to 're0.103'
v 22 05:36:32 lb php-fpm[347]: /interfaces.php: MONITOR: VDSL_OTE1_PPP_PPPOE is down, omitting from routing group Default_Gateway_Group_ipv4 80.106.125.100|2.86.52.251|VDS
L_OTE1_PPP_PPPOE|14.683ms|0.578ms|90%|down

and then keeps spitting errors in ppp log like above

i've just discovered that adding a new vlan leaving untouched all others vlan used or not by pppoe breaks all pppoe connections. very sad.

netblues

Yep, thats true.
Adding a vlan brings down ALL pppoe connections.
Easy to replicate.

I've got a single WAN - PPPoE on VLAN. I Just tried to replicate this.

If by "adding a VLAN" you mean going to Interfaces > Assign > VLAN > fill out the form > then click "Add" - I just did this, and it did NOT take my PPPoE down.

I then went to interfaces > Assignments, selected the VLAN I just added as an interface from the "Available network ports:" dropdown, clicked "Add" then "Save" - that still did NOT take my PPPoE down.

Finally, I went to interfaces > OPT2 (That was the interface name assigned), then ticked the "Enable Interface", Leaving both "IPv4 config type" and "IPv6 config type" as "NONE" - and that did it. I could no longer access internet. The WebGUI was unresponsive. Fortunately, about 30-45 seconds later it came back - PPPoE was up but it had obviously disconnected and reconnected.

Lastly, I went to disable the interface (unticked the box next to "Enable Interface") - this completely killed my internet. PPPoE went down and shows as disconnected. Here's whats in the logs:

I had to go to Status > Interfaces and manually hit "connect" - now everything is back to normal.

My pfSense spec

4 CPUs: 1 package(s) x 2 core(s) x 2 hardware threads
AES-NI CPU Crypto: Yes (active)

4 x igb0 Interfaces (only 2 in use - one is my WAN and one is my LAN)

Installed Packages

Everything is the latest version at time of writing.

Ok, try this patch if you are able. It should work against 2.4.4 and 2.4.5snapshots:
https://github.com/pfsense/pfsense/commit/433a8e71f3b68c39634e11b62d8bf3d9e8ec878c.patch

You can apply that via the system patches package. It resolved the issues I was seeing. It will be in 2.4.4p1.

I can confirm, the patch fixes it. (appplied to a 2.4.4 system, updated from 2.4.3).
I will move it into other boxes on the first available maintenance window

Thanks

Made my own thread as I did not find this on my first search for a solution (https://forum.netgate.com/topic/138802/lan-interface-makes-wan-not-receive-address-from-isp)

2.4.4_1 took care of all my problems.

It's reproducing in 2.4.4-RELEASE-p3 , difference is errors logged in /var/log/system.log instead of /var/log/ppp.log

If I recall correctly fix is to be included in the 2.5 release.
So apply the patch above.
It causes no harm on 2.4.4p3 and certainly fixes the issue.

stephenw10

That patch is already in 2.4.4p3. You can only revert it with the patches packages, and you don't want to do that!

Ar you running 2.4.4p3 clean? Did it just start happening?

I've not seen this myself or any other reports of it since that patch went in.

At first i've upgraded to 2.4.4-RELEASE-p3 . Problem haven't gone. Then i've applied that patch above yesterday (by System_Patches plugin) . Today morning i've lost my pfsense again. In the ppp.log i see now:

How did you apply the patch? It should not be possible to apply it to 2.4.4p3 as it's already present. If you were able to then your install is in some odd state.
