Yeah, you should see it responding to arp requests if it's actually conected. Assuming that's what that tool does.

At the console menu choose option 8 to drop to the command prompt.
Then try to ping something local. For example:

ping -c 3 10.0.0.88

If it's connected correctly, and the host machine responds to ping, that should work.

Now try to ping some other things. Try to ping an external IP.

Check the routing. Run:

netstat -rn

Make sure it has a valid default route.

Thanks, I'll give that a try when I next stick it back together again. I could always do a tcpdump and see what's coming across the interface.

@stephenw10 It's a little late, I've been distracted. I decided to just do a fresh install, hoping maybe some setting was off. After installing and almost no configuring at all and only WAN and LAN, I fired it up and it made a huge difference, instead of getting only about 17Mbps on a 100Mbps bandwidth internet connection, I was now getting a whopping 1.6 to 1.8 Mbps! I've checked as well as I know how to find some mismatch in the settings and can find nothing. I got disgusted and swapped my router back in. Using the NIC directly on the PC that was running pfsense with pfsense not running, I can get the full bandwidth, so it's not some problem with the NIC. If you or anyone else has any ideas I can swap pfsense back in easily enough to try them out but otherwise, I'm going to put it aside for now and when I have more time I can try it again, maybe start a new thread if the problem persists. Thanks for you help, it's been appreciated.

I had this problem for about 6 months,
I had this problem with cell phones, TVs, routers and some virtual machines
Every day I got this problem and the only temporary solution I had found was to clear the arp table, so 99% of things worked, until they were turned off
Earlier this month I turned it off, installed another firewall and left my network like this:
pfSense on the 192.168.5.1 network
another firewall on the network
192.168.4.1

And so I was changing device by device from one network to another, until I moved my loadbalance and everything stopped, I moved it back to the old network and it started working again

I recommend that you do this manual method, if it is interference, it is the best way to find it

[mechtheist]

@giovanni-0
Thanks for the reply. My network really isn't that complex, I've never set up load balancing. In this latest attempt, there was little else going on with anything other than pfsense and the PC its VM was installed on that I ran the tests with. It was a fresh install with almost no config changes and it got only 1.8% of the actual bandwidth available. As I mentioned in OP, I've been doing this for years with much less capable PCs and never had problems. It makes me thing there's some box checked off somewhere, or not checked off and I'm just too stupid to see it.

Thanks again.

@mechtheist

This looks like a hardware issue to me. Check the storage device on the system that hosts your VM. Check the system RAM as well. The fact that you reinstalled pfSense, and you had those issues where CPU load status indicator is not loading, is leading me to belieive there might be something wrong with your hardware. We already know that NIC is fine, thats one thing ruled out, check everything else. Verify your VM settings as well. There could be an update that reverted your CPU/RAM/Storage settings for your VM. Its pointless looking for an issue in pfSense until the host system is not checked.

[stephenw10]

Hmm, this seems more like VBox issue to me.

Can you try running in Hyper-V instead?

Or, better, running bare metal as a test?

I've had this problem for many months and looked but have never found anything that I could determine to be a possible cause in pfsense or the PC. It's weird that doing a fresh install and little configuration dropped the already low bandwidth by a factor of almost 10, from about 17Mbps to about 1.7 Mbps. I have v v little experience with Hyper-V and none with any other VM software but I was starting to think about trying Hyper-V . For about 6 years at least I've done this with VirtualBox and had no real problems, pfsense just worked, it's always kinda amazed and really impressed me.

That said, a couple of hours ago it crashed, below is the report copied off the web page, I don't even remember getting one of these before and definitely don't have the knowledge to understand what it's telling me, anything stick out to you guys? I don't know how to fix the nonprinting characters, sorry.
Had to cut a lot out, too long, so attached file. Thanks for all the help!

@mechtheist

At this point, the fact that some devices are connecting and some dont, is completely irrelevant. You did a fresh install of pfSense, and your traffic speed was cut anyway. Thats not how clean install of pfSense performs under normal conditions.

Lets try again.

1. Did you check VirtualBox VM settings ?
2. Did you test system RAM on the machine that hosts your VM?
3. Did you check the storage on the machine that hosts your VM/VM Images and OS ?

That's the important part there, the backtrace, and it's inconclusive.
But it is showing an issue in IPv6. Maybe your old config didn't have IPv6 enabled at all?
Maybe your ISP jusy turned on IPv6 (or some port of it) and it's broken? Or your config is somehow not compatible with it?

I would be testing pfSense bare metal if you can't try hyper-v.

@mechtheist

At this point, the fact that some devices are connecting and some dont, is completely irrelevant. You did a fresh install of pfSense, and your traffic speed was cut anyway. Thats not how clean install of pfSense performs under normal conditions.

Lets try again.

1. Did you check VirtualBox VM settings ?
2. Did you test system RAM on the machine that hosts your VM?
3. Did you check the storage on the machine that hosts your VM/VM Images and OS ?

1>I've been checking the VM settings again and again for months, I can't find anything that looks anomalous to my fairly ignorant eyes. I have been doing this kind of setup for years and never had this issue until recently. Do you know if something changed in pfsense basic setup in the past year that would adversely affect compatibility with basic, typical VM settings?
2> Do you mean a full blown MEMTest kind of thing, running it for many hours kind of thing? No, that I have not done. I haven't had any issues that look like memory problems, it's not unusual to use a good percentage of 64GB. The problem has persisted for a long time with numerous substantial changes in the VM, the VM is loaded and run in a LOT of different orders wrt the other programs running on the PC, which is used for a LOT of different applications. I don't see how memory problems would be at all likely considering these facts, but if you think it's still worth doing, I will try to do but doing one of those is a hassle.

3>I'm not sure what 'check storage' implies, I just did a windows check drive and it found no errors. It's a newish Samsung Evo NVMe. This problem has persisted through multiple virtual disks created for the pfsense VM, new ones with the old ones left alone. I've never had any kind of indication that there was any kind of disk problem for this drive. I've probably gone through at least 6 completely new VMs, new virtual disks, etc. Considering this scenario, if there were disks problems, it sure seems like I would have had some indications, it doesn't seem like I would have very similar problems across multiple virtual disks which would be very different locations on the disk especially with it being an NVMe. Also, this is a network bandwidth issue, not sure how a disk problem would degrade throughput on the network.

I appreciate your efforts, thank you. I will have another post shortly that has some more info.

I always have pfsense block all ip6 traffic, i have enough problems [ignorance and stupidity] with understanding what's going on with ip4. There's always ip6 crap going on though and I'm woefully ignorant about what it means or actually even is, though most of it that I can figure out is linklocal kind of stuff. That said, on the terminal screen for pfsense, it started listing an ip6 entry for the WAN along with the other interfaces, but I think that was when I had the WAN cable disconnected and was trying to do other things.

Is Hyper-V considered bare metal? I've used VirtualBox for a long time and I'm fairly confortable with it and it has always worked well and without issues, I hate the idea of going with something different and facing the learning curve.

[mechtheist]

As I was dicking around with it, the pfsensee VM was getting really sluggish, Running top from the terminal/console, there was a lot of heavy cpu usage that wasn't normal, there was not anything like heavy traffic for it to contend with, but I was getting a lot of different applications showing very high cpu usage, a lot of it was php-fpm, also unbound, bzip, sh, rate, even ps. Often numbers in the 60s and 70s, often higher, sometimes over 100% and a couple of times I'd swear it said something like 1000%, but I'm not sure if I was seeing that right. I don't really have the time to be fooling around with this so I'm back on a router for now and I'm not sure what to do or if I want to spend much more time with it. This is the kind of times that defenestration starts to look good.

[nimrod]

@mechtheist

OK. So VM settings are ok. You dont have to run full blown mem test. That will take days to complete with 64gb of RAM. Just run quick test from pure DOS mode which will test CPU/RAM memory controller. As for storage, windows check only verifies integrity of files and file system, and in rare cases, it will run surface test if windows itself suspects that there are bad sectors on the drive. Anyway, thats not enough. Since you have a nice Samsung nVME, just download and install Samsung Magician SSD tool from Samsung website. That tool will read S.M.A.R.T parameters and perform quick test to see if your drive controller and drive itself are OK.

In your last post, you mentioned high CPU usage and sluggishness. None of such things can be caused by default pfSense installation. It all indicates issue with either hardware or host operating system. Try removing Windows network loopback driver and reinstalling it again.

When we say "bare metal" we refer to pure hardware. No virtualization. This is to rule out any potential missconfiguration or issues with hardware or software. Hyper-V is just virtualization software that Microsoft built into the Windows 10. Its similar to VirtualBox. You can try it, but as @stephenw10 already said, its better to try on bare metal.

@mechtheist said in Some hosts aren't connecting to the internet but others are:

A real IPv6 address? That didn't exist before?

That's the sort of change that could be introduced by your ISP and if not setup right (or completely disabled) can make the experience at a client seem very bad. Though it usually presents as a delay before anything starts loading rather than slow throughput.

Days for a memtest, that's depressing because my other main PC IS having a subtle thing going on that is likely a memory issue and I've been putting off testing due to how much time it took, it's also 64GB, and I thought maybe it was 8-12 hrs, it's been a really long time since I've done one of those. I'll try a DOS mode test.

I used to have Magician installed but removed it, forgot why, I tried to reinstall it with latest version I just downloaded and got this:

Not helpful, I can't even figure out who's objecting, Windows doesn't mention it in its virus security settings nor does Malwarebytes, but I put in an exception in both of those and still getting it, it must be part of the install program itself [probably likely as it has that 'Setup' bit showing] and not sure what to do about that, maybe there's a log entry, will have to deal with later. On a positive note, I have CrystalDiskInfo that I run from startup and it isn't reporting any errors, so shouldn't be any SMART issues.

I wasn't sure about bare metal, I think I've read about some of the higher end VM tech is much better at bringing your OSes closer to 'bare metal' so I thought maybe that's what you meant. I have like 4 or 5 older PCs I might drag back out and try. There is an issue I will mention in next post in answer to stephenw10.

Thanks again for your efforts!

Not sure what 'real' ip6 implies, I should have done a screen shot. It was there only when I was first dicking with the new pfsense install and didn't have the WAN connected, so it can't be an ISP thing.

I had an idea that made me want to facepalm, maybe it's the NIC after all, I'm using a Intel PRO/1000 PT Quad Port Low Profile Server Adapter, it uses a 82571EB Gigabit controller, I searched the forum for any info and found one of your posts from just a couple of months ago here:

PCIe 1 vs 2

Some virtualisation support in the 82580.

But 82571 is an em(4) NIC but 82580 is an igb(4) muti-queue NIC. If you have multiple CPU cores that is going to load them far more efficiently.

There is non-low profile version of this NIC that only supports PCIe1 but the LowProfile version is supposed to have the ability to work with PCIe2 through some kind of addon chip or emulation or ??? Could that be the problem? With the PC connected to the LAN through the quad NIC it can do 100Mbps just fine. That's from the internet with Ookla speedtest. I ran a local test and got this:

and that's while using RDP to run the test so it had that traffic to compete with. The FreeBSD manual page for the em driver doesn't actually list the lowprofile version, it has a LOT of the similar cards though. Mine is the 'PT' variety, not sure what the difference is with the PT, MT, PF, MF etc versions. Does any of that mean anything to you and is it a possible reason for what I'm seeing, could the low profile kludge be the culprit? I appreciate all the help, thanx.

@mechtheist said in Some hosts aren't connecting to the internet but others are:

I mean a globally routable public IP as opposed to a link-local IP based in the MAC address which every interface has.

An 82571 NIC will easily pass 1Gbps with any vaguely recent processor. Unless it's something ultra low power maybe, but any system designed for that wouldn't be using that NIC.
I wouldn't expect any issue with that.

OK, I switched the LAN and WAN to the mobo's onboard NICs and no change, then did a new install of pfsense and no change, if anything it was even slower.

I used to drool at the thought of getting a 1Mbps internet connection, a 'T1' I think I always heard them called, but that was a long time ago. So it's not the NIC, here the quad NIC isn't connected in any way. I was also immediately after the new install getting anomalous cpu usage again:

That's what it looks like, the right two are from earlier examples, the left one is from this new install, I saw a number of 3-400% figures, just didn't catch with the screenshot.

The ip6 address popped up again and I see now what happened, pfsense seems to have a lot more ip6 stuff going on and set up as default, there's at least 2 or 3 settings I had to switch off, kept getting 'you can't do that because X is turned on' kinda thing, I really don't recall having to do any of that before.

One strangeness I noted was the syslog was full of this:

Nov 16 14:29:34 	nginx 		2021/11/16 14:29:34 [error] 33672#100684: *11813 open() "/usr/local/www/cgi-bin/luci/;stok=df714b094f1a294eb62bd685e32d868d/admin/status" failed (2: No such file or directory), client: 10.0.0.40, server: , request: "POST /cgi-bin/luci/;stok=df714b094f1a294eb62bd685e32d868d/admin/status?form=wan_speed HTTP/2.0", host: "10.0.0.1", referrer: "https://10.0.0.1/webpages/index.html?t=0093dbde"

There were 4 of the first line followed by 496 of the second one. 10.0.0.40 is my main PC that I'm on now, not the PC with the VMs. So the whole log file was just this crap which means absolutely nothing to me.

I realized trying it bare-metal meant to run pfsense on the same PC I have it virtualized on, it makes no sense to use another PC, I've been thinking of doing that to 'solve' this problem but that wouldn't help figure out what's going on with the VMs. I could just try running it live, that shouldn't be too intrusive, installing it would make me really nervous I'd break something, I'm not that good with boot loaders and the like and zfs is utterly opaque to me.

[stephenw10]

Hmm that's a lot of awking! I'd try running ps -auxwwd to see what it calling that command.

Those errors are something on 10.0.0.40 trying to open a page that does not exist on pfSense.
And the page it's looking for, /cgi-bin/luci/, is from OpenWRT so I suspect you have ha another router at 10.0.0.1 running that at some time.

A restriction to ~1Mbps almost has to be some link issue or something in the VM setup.
