24.7 Production Series / Re: Loosing WAN every 15 minutes

« on: August 16, 2024, 09:02:37 am »

Thank you for the clue.
If this is the cause for my trouble I'm greatly embarrassed for not sharing the whole config here. I got ntopng running on .220 and it's networks discovery is set to run every 15 minutes...

Found this: https://github.com/ntop/ntopng/issues/4861
If it is this, still odd though:
I got ntopng running on multiple other sites installations, haven't seen this anywhere else.
When I have another host active on one of their other assigned static IPs there is not a problem.

And... it looks like it may have been the culprit. I now passed two 15 minutes interval with only .220 running and Network Discovery disabled in ntopng.

And here is a capture on the Hyper-V host. The physical machines interface were the ISP is connected.
I got a drop at 20:30:13. Only had the .220 MAC .01 running.

24.7 Production Series / Re: Loosing WAN every 15 minutes

« on: August 15, 2024, 08:09:13 pm »

Tell me if this just confuses things or doesn't add anything to what we're trying to figure out here.
I saw your question about packet capture directly on the host, I'll try that.

I got a 24.1 up and running on .222 MAC .05. Purpose to check if this runs without the drops. 

It passed the magic 15-minutes with grace at 19:30. No drops there what I can see or notice.
And... so did .220 MAC .01 ... This doesn't compute for me. If I got .221 MAC .02, Then Windows Server active then the problem doesn't occur either. Now that I got a 24.1 up and active on .222 it looks like that also removes the problem.
I'm going to try to shutdown .220 and leave 24.1 .222 alone on the connection to see what happens a little later.

« on: August 15, 2024, 07:00:09 pm »

I don't see requests coming in from your ISP gateway - these would (if I understood the topology correctly) end in "Tell xxx.yyy.zzz.194". There isn't any.

So possibly they are not passing your Hyper-V infrastructure to arrive at OPNsense ...

HTH,
Patrick

I captured new data.

Code: [Select]

447 18:30:00,856682 Microsoft_01:99:01 Broadcast ARP 42 Who has x.y.z.194? Tell x.y.z.220

Is it this we're looking for? Or should I see a timestamp and the MAC-address of the gateway .194 telling where stuff is?

At this capture I lost the connection exactly at 18:30:00.
Started it at 18:29:36, stopped 18:30:50.

Did you run a tcpdump on the WAN interface to watch if these ARP requests really reach your OPNsense and if they match your IP address etc?

I used the function within opnsense and used the WAN, hn1 in my case, with promiscuous mode enabled. The filtered output is in the first post. The .220 is the static IP on the interface and .194 is the ISP gateway.
I hope I understand your question right here.

Look at the Hyper-V switch logs, maybe there's something there. Also, any Windows update can break/change things.

Logs, lots of information entries but nothing related to ARP or this as I can see. Looks good.

I've scrutinized the the vm and vm host config thoroughly and can't see any problem with it. As I run multiple installations like this which works as they should, the config of the vm and vm-host isn't my #1 suspect 

For what it's worth and reference, attached the vm-switch and vm-nic config here.

And want to give you both a BIG thank you for assisting me here. KUDOS!

I checked

https://www.freebsd.org/releases/14.1R/relnotes/

But nothing came up. A lot of code shifted. I'm not sure where to look.

A packet capture might tell us if it ever responds to ARP on WAN or stops at some point...


Cheers,
Franco

Got a capture of the event, but not sure if it's safe to attached that here. Can I dm you that file maybe?
In the first post there is a txt-file file filtered on DHCP and ARP, what it looked like in WireShark.

ISP and WAN IP presumption you make is correct.

Yeah, know there are some sceptical thought about the vm, hyper-v, thingy here  . But the problem was introduced recently. The ISP claims no changes in their side. And the change I've made is upgrade to 24.7, and had no problem like this before.

Hi again!

Looks like the problem started with 24.7.

The ISP and fiber deliverer returned with this:
"They could see from their end that your device does not respond to ARP probes sent from their side every 840 seconds."

So, something is up with the latest update, this is my low-level-amateur conclusion. Any chance that underlying ARP-handling is borked in the latest updates?

Hi and thank you for a somewhat creative suggestion.

I've have no problem with this way of running it, I got multiple installation at various sites all running virtualized (and have done so for years). This site starting acting like this with 24.7 or 24.7.1 so wanted to reach out here to find a solution or to point out a potential problem.
All other sites are running 24.7.1 now but are not on this kind of "multiple ISP in the same fiber" solution. And they work. Trace Route ICMP broken tough.

To add, and why I though this maybe related, is that tracert using ICMP is not working either. I refereed and asked about a other thread here were people had problem with tracert in the latest version of bsd kernel/opnsense.

UPDATE, Forgot that I had a snapshot of the virtual instance from 24.7_9 so reverted to that.
Trace route works again but I think I still see the 15 minutes losses.

I've just setup a new-previous version 24.1 in parallel on a different WAN-IP and is checking that out to see if it experience the same drop/loss. If that version works then I'll switch to that and wait out a possible fix for 24.7.

Will circle back here with the results.

(everything is done remotely for this site so need to be cautious with how I proceed...  )

Hi!

Thank you for the response.

I've been in contact with the ISP again, and it their recommendation was to lower the arp timeout. I have set the net.link.ether.inet.max_age=120. Problem persist.

On their recommendation and troubleshooting steps I was asked to test from another device.
I've now got a Windows Server 2022 on one of their other static IP-addresses to monitor what happens every 15 minutes.

What I understand this is a connection called "Stadsfiber"(swedish name) translated to "City Fiber". It's "virtual" "thingy" as it can be multiple ISPs providing services through this fiber.
If the customer, as in this case, want static IP-addresses they provide that and use arp to update and assign them. OPNsense is configured with one of these assigned static addresses.

The problem showed first on 24.7 no problem before that, I think. Made the upgrade all the way to 24.7.1 in one sweep so not certain if it was 24.7.1 or 24.7 that introduced the problem.

Please tell if I can provide more info.

UPDATE while writing this. This is more than strange.
If I have the other machine, a Windows Server 2022 in this case, active on one of their other static addresses the problem goes away?!? No more 15 minutes losses...

I'm working with the support at the ISP right now to try to figure out what's going on.

Hi!

Need some help to get on the right track here I think.

Loosing WAN connection every 15 minutes as the title says.

I am having the same issue

"Great" that I'm not alone So, maybe this needs some eyes from a developer perspective.
I'm not sure when it started though, you got a that? I think it was 24.7.1 but not sure.

Can it be related to this kernel-thingy maybe, 24.7 / 24.7.1?

Hi!

Need some help to get on the right track here I think.

Loosing WAN connection every 15 minutes as the title says.

Was in contact with the ISP and they hade some theory that matches up with the times of events. :00,:15,:30,:45.
The WAN-connection is a static IP-address and they use ARP to assign it according to them, that every 15 minutes.

They also talked about a setting, ignoring not matching ARP(?!) This is where I have a hard time understanding what's happening.

Don't know if it's worth anything but attached a Copy/Paste of wiresharks packet list filtered on ARP and DHCP.
(_ws.col.protocol == "DHCP" || _ws.col.protocol == "ARP"  || _ws.col.protocol == "BOOTP")

Everything is updated to latest available as of now.
