Why did my WAN drop and not reconnect?

stephenw10

What is igc0 there. At 4.09 it lost link. So whatever that's connected to rebooted or maybe there's a cable issue.

It linked back 3s later which started a new mpd process. But it looks like the old process was still running and they are competing.

Do you have any VIPs on the PPPoE interface? https://redmine.pfsense.org/issues/14434

igc0 links to my ONT (optical network termination unit).

I'm sorry I don't know what you mean by VIP's, is this something my ISP may be able to answer?

rivageeza

Ah virtual IP. It's not something I've configured.

stephenw10

Ok so igc0 lost link do you know if the ONT rebooted?

Check the chipset version for igc0. Some of the early variants of igc are known to have issues that can present as losing link.
Run: pciconf -lv igc0

Sorry for the late reply.

Outcome is igc0@pci0:2:0:0: class=0x020000 rev=0x04 hdr=0x00 vendor=0x8086 device=0x125c subvendor=0x8086 subdevice=0x0000
vendor = 'Intel Corporation'
device = 'Ethernet Controller I226-V'
class = network
subclass = ethernet

It's happened 3 times this weekend. WAN drops out, pfsense hasn't locked up and ISP state it's nothing their side.

It's getting to the point where I may have to go back to using my ISP router but I really don't want to.

I would try re-assigning WAN to one of the other NICs to make sure it's not just a bad port.

If you can use something that isn't igc I would try that but I imagine all the ports are igc.

That igc NIC shows as rev 4 which should be OK but....

@stephenw10 Will give that a shot. Thanks. Will feedback.

We seem to have a similar issue.
Here is where I am at: https://forum.netgate.com/topic/185096/pfsense-fails-badly-and-it-is-a-sad-day/1
If you find a solution I am interested.

pciconf -lv igc0

igc0@pci0:86:0:0: class=0x020000 rev=0x04 hdr=0x00 vendor=0x8086 device=0x125c subvendor=0x8086 subdevice=0x3037
vendor = 'Intel Corporation'
device = 'Ethernet Controller I226-V'
class = network
subclass = ethernet

pciconf -lv igc1

igc1@pci0:87:0:0: class=0x020000 rev=0x04 hdr=0x00 vendor=0x8086 device=0x125c subvendor=0x8086 subdevice=0x0000
vendor = 'Intel Corporation'
device = 'Ethernet Controller I226-V'

So it stops passing traffic entirely but only on the WAN side?

If you run a packet capture does it show anything when it's in that state?

mikek

@stephenw10
so it fails dpinger, goes offline. then one of 2 things happen

vpn successfully reconnects with wan still failing. traffic goes out vpn for a while. then vpn fails as well.
all successful traffic fails.

As for packet capture, been a few months since I did that, if I remember right there were outbound packets with no responses. until I bounced the interface or rebooted the FW
Yes, I tried putting a switch between router and modem. didn't make any difference. same behavior.
tried a bunch of the things that people post as solutions, with no success.

Hmm only other thing I'd check is the MAC stats in the sysctls to see if that shows anything coming in at all.

mikek

@stephenw10
"MAC stats in the sysctls" Guess i need to look that up and do some learning. thanks.

stephenw10

Check in sysctl dev.igc.0 for example
