PPPoE WAN connection drops

[krzysztofb]

Hello

I know there are many PPPoE-related topics here (and in other places), but I did not find any help so far...

I've upgraded from the TPLink router to OPNSense (mini PC: GIGABYTE GA-J1900N-D3V Mini ITX with dual NIC / 4G RAM / 120SSD + 320GB HDD for logs) to get some more control, security, and extra functionalities but having trouble fixing my PPPoE connection...

I've been struggling with this for 2+ months now, I have tried googling for some help, and found similar problems, but none of the solutions mentioned (eg. "Disable Gateway Monitoring" or removing IPv6 gateway) there worked for me...


The problem is that PPPoE goes down occasionally, and the only thing that helps is a reboot (just restarting the interface has no effect). As a workaround, I created some shell script and added it to cron, so it checked every minute if there is Internet access, and if not, it reboots the router. Problem is that it takes some time, and if it occurs a few times a day, it is quite annoying.

From my observations, it occurs more often, when traffic is high (eg. I run speedtest.net or saturate the connection with multiple downloads and other high traffic use), but it happens occasionally, even with very low LAN/WAN traffic.

Your mainboard uses Realtek NICs which have some known problems which are discussed all over the place.

Did you try the vendor drivers (plugin os-realtek-re)?

[franco]

There is indication that mpd5 has reconnection/renegotiation problems and a workaround exists:

https://sourceforge.net/p/mpd/discussion/44693/thread/7a19aeb247/

If it's actually the problem here or some other type of link down issue mpd5 is powerless against I do not know.

I have tested multiple different configs, starting with:

set bundle period 6
set bundle lowat 0
set bundle hiwat 0
set bundle min-con 3
set bundle min-dis 6
set bundle enable bw-manage

And no luck so far. When my 1G WAN gets saturated, PPoE drops and reboot is needed (interface restart does not help).

Does anybody face same issues?
