Description

In some situations PPPoE fails to reconnect after an upstream outage or making a change locally. The system file logs:

Nov 21 16:45:32 pfsense ppp: [wan_link0] Link: reconnection attempt 4
Nov 21 16:45:32 pfsense ppp: [wan_link0] PPPoE: can't connect "[1b]:"->"mpd17126-0" and "[4e]:"->"left": No such file or directory
Nov 21 16:45:32 pfsense ppp: [wan_link0] can't remove hook mpd17126-0 from node "[1b]:": No such file or directory
Nov 21 16:45:32 pfsense ppp: [wan_link0] Link: DOWN event
Nov 21 16:45:32 pfsense ppp: [wan_link0] LCP: Down event
Nov 21 16:45:32 pfsense ppp: [wan_link0] Link: reconnection attempt 5 in 4 seconds

This appears to primarily affect PPPoE connections running over a VLAN but there have been reports of it in general.

It brings down all PPPoE connections when this happens regardless of where the local change was made.

History

#1 Updated by Rai Wol 5 months ago

I can confirm. After making a change to one of the interfaces and hit apply, my pppoe connection over vlan 6 disconnects and doesnt reconnect automatically. When I goto Status->Interfaces and hit Connect sometimes it succeeds but most of the time it fails and I need to reboot the firewall to get pppoe connected again.

#2 Updated by net blues 5 months ago

Just adding a new vlan also brings down all pppoe interfaces, with the same exact error.

There looks to be a good chance this is resolved by this:

https://github.com/pfsense/pfsense/commit/433a8e71f3b68c39634e11b62d8bf3d9e8ec878c.patch

Applying that prevents the issues I was seeing when interface changes are made. Waiting to see if it corrects issues caused by the link failing.

This fixed it!

#7 Updated by net blues 5 months ago

I can confirm this fixes the issue.
I also created a failure upstream bringing down one ppp interface. The rest remained up, as expected.
