pfSense 2.7.0 stop working now and then

You have adguard running locally?
Split-DNS is generally the best solution if you can use it. How does it fail in the cases it doesn't work?

More likely the client isn't using the Adguard server. I'm not that familiar with Adguard, I'd check any logging it has to be sure it's actually seeing those failing queries.

@stephenw10 said in pfSense 2.7.0 stop working now and then:
Yes, that will prevent it selecting the LAN gateway as the default if the WAN has a glitch. Which is probably what has been happening.
However you almost certainly should not have gateway on LAN. You would only have that if you have additional downstream routers with subnets behind them pfSense has to route to.
The only other time is for the policy modem IPSec workaround.Steve
I still have the issue... I found this in the log
Sep 11 15:14:30 rc.gateway_alarm 2071 >>> Gateway alarm: WAN_DHCP (Addr:158.174.25.129 Alarm:1 RTT:.102ms RTTsd:.040ms Loss:21%)
I have to reboot the pfSense to get it working again... any idea and/or solution for this?
-
The WAN stops passing traffic? It never comes back up until you reboot it?
If it happens again try disconnecting and reconnecting the WAN cable; does that also bring it back?
-
I haven't attempted it yet, but I'll give it a try next time. This incident occurred after a gap of 9 days since the last occurrence, so it's not happening frequently, but it's still quite frustrating. Today, both my wife and I were in Teams meetings when the WAN connection suddenly went down.
I see now that I have lots off in-errors... is this the reason? What can explain this?My setup looks like this;
WAN <- 10 Gbit fiber -> SFP (DIGITUS 10 Gigabit mediaconverter) RJ45 <- 2.5 Gbit Ethernet -> RJ45 (pfSense Hunsin RS34g-J4125 FNR-RS34) RJ45 <- 1 Gbps Ethernet -> LANI replaced the cat6 cable for the "2.5 Gbit Ethernet" link inbetween the media converter and the pfsense-box... but I still gets error;
-
Seeing errors like that is not necessarily an issue. It depends what sort of errors those are. There is probably more detail in the MAC stats. And the actual percentage of error packets is low.
However seeing collisions is odd. You should never see collisions on a switched segment.

What is the underlying reason for collisions? I only have two devices, the fiber/Ethernet converter and the pfSense. Is it possible that the media converter is causing the collisions, or could the issue originate from the ISP's end?

As far as I know media converters like that are only media converters. They have no switching. So the segment over which collisions might occur is between the pfSense NIC and whatever is at the remote end of the fibre. It may not be a problem. It's still unexpected though.
Can you swap the WAN to a different NIC in pfSense?

Certainly, but in that case, I'll receive a new MAC address that will require updating with the ISP... but I'm willing to give it a try if it's worth it.
Should I use a crossover cable between the media converter and the NIC of the pfSense? Currently, I am using a Cat 6 patch cable.
My converter converts 10 Gbps SFP to 2.5 Gbps Ethernet… can the lower speed of the inbound traffic cause the collision we see?
-
You shouldn't need a cross-over cable. It shouldn't matter. Anything using 1G Ethernet or higher should be auto-MDI/X. If it did require it it would be failing completely.
Is the media-converter actually linked at 10G on the fiber side? If it has to buffer the traffic between 10G and 2.5G it could be causing problems.
You can spoof the MAC address on the WAN interface to match whatever the ISP has registered. I would definitely try swapping the WAN NICs though, however you achieve that.
The actual amount of errors and collisions shown is pretty small. I wouldn't expect that alone to cause the WAN to stop passing traffic entirely.
Steve
-
Only on incoming data:
Collision: 0,5%
Errors: 0,45%outgoing data is without error/collision...
-
Is igc0 the same NIC?
You can looks at the type of errors those are in the sysctl macstats:

Looks promising!
no...
still errors and collisions... should I enable h/w CRC again?
My current settings;

Since it made no difference it likely doesn't matter. I would try swapping the NICs next. If it follows that then it's probably real incoming errors. I'd probably look at swapping out the media converter in that case though that might not be practical.
However I still don't think those errors/collisions would cause the traffic to stop entirely. At most those are symptoms of some other failure.
