Hi guys,

So.. testing multiwan on my system...
I have a WAN1 which is my PPPoE link and WAN2 which is a Mikrotik with a Huawei 3G modem in it.

I configured a failover group with "packet loss", having as TIER1 the IPv4 gateway of the PPPoE link and as TIER2 the IPv4 gateway of the Mikrotik.

OPNsense crashes every time I disconnect the PPPoE link from Interfaces: Overview.

I submitted the crash report from the WebGUI, don't know if it got uploaded...

Any ideas what's happening?

Did you set it up like in the docs?

Yep...
If I restart and the WAN is still down (the interface physically disconnected), it never comes back, no network, no GUI. I think it keeps crashing. I don't have a monitor attached to it as it is back in the rack so it's just a guess.

Screenshots from all Gateways please. Surely related to apinger

And please start with Neighbor Down and not Packet loss

Screenshots attached.

OK, switched to "member down". Will get back with the results, I'll try a simple PPPoE disconnect.

UPDATE:
Nope, either it panics and never reboots, or simply just hangs. I had to reset the box.

I noticed that first RDS_DHCPv6 is first reported down in the GUI.
WAN2 is still up, managed to stabilize the modem.
Then my guess is it crashes when RDS_PPPoE is down as well, cause after that, no GUI, no network, and from what i'm seeing, it doesn't come back until a physical reset.

Another update: I disabled the IPv6 gateway monitoring, but didn't help, still crashes.

mimugmail · « **Reply #8 on:** March 30, 2018, 05:36:21 pm »

Please disable V6 completely .. just for testing

elektroinside · « **Reply #9 on:** March 30, 2018, 06:15:44 pm »

Nope.. same thing.

Submitted another crash report package. Do these work btw? Where are they stored (I'm guessing & hoping that they are privately available to the devs - didn't read any confidentiality agreement or similar).

mimugmail · « **Reply #10 on:** March 30, 2018, 08:43:28 pm »

Hm, OK, without a Display it's just guessing, sorry

elektroinside · « **Reply #11 on:** March 30, 2018, 09:07:44 pm »

I disabled "Sticky connections" and "Shared forwarding" and no more crashes.
Narrowed it down to these two.

Multiwan works fine now, I think, I just did a few tests. IPv6 is gone on my PPPoE once I reconnect, but this is known and it's getting a fix soon.

Although I don't think we should consider the issue closed. It shouldn't crash, right?

Anyway, thank you mimugmail for your assistance.

Regarding the monitor part, I attached a picture of my rack. It is close to impossible to connect anything anymore there, not to mention I need a ladder to get up there...
I have to take everything out every time I need to connect a display to anything.

Be aware that you can't use Traffic Shaping without Shared Forwarding!

I'd be interested in the system.log at the time it crashes (console would be way more cooler).

elektroinside · « **Reply #14 on:** March 30, 2018, 11:09:26 pm »

Yeah, I know, I don't use it anyway. But it would still be better not to use it and not get a crash...

Ok, I'll collect the logs tomorrow, I'll send you a PM with a gdrive share.
