  I hope this thread is still alive :) I was using m0n0wall for a long time (still have one that's been alive without reboot almost 7 years!) before I came across the first customer needing VLAN, about 12 years ago I think. I got recommended to check out pfsense, and I have since then never looked back. These days I run my own company and importing hardware and building our own routers based on APU2 board and pfsense. We have at least 200+ installations out there, and we're also running pfsense in our small datacenter where we maintain our smallest customers, as well as the two geographical backup sites we keep for customer data. And, at home of course, where I hide my entire network behind an OpenVPN service setup in pfsense. I'm originally a Windows-guy, but after I met pfsense I realised there's a whole world of open source out there so I started learning, and today roughly half of our services are based on open source. Comparing pfsense to Cisco or the likes, I'd say there is no competition when it comes to price / functionality / reliability (as long as you use an appropriate hardware). Only kind words from me! ...and were are also retailers for Netgate in Sweden, not that we have a lot of customers of the size demanding that good hardware.

  If this is not a public WAN-type environment then all you have to run is this: pfSsh.php playback enableallowallwan That is all I do when I make a new lab VM. Standard disclaimer about not doing that on an actual public interface yadda yadda yadda applies.

  So internet in general was working, you had no issues resolving anything.. Just speed test was failing? And you had tried just changing the servers you were doing the test too? That latency error you were getting seems to just point to one of there servers being down https://support.speedtest.net/hc/en-us/articles/203845540-What-does-Latency-Test-Error-mean- "Latency Test Error" typically occurs when the server has gone temporarily down. We have a server watchdog that will periodically contact servers to verify they're working properly, but there may be a slight delay before we automatically recognize the server is down. Please let us know by filing a support ticket specifically identifying which server caused the error, and try testing to a different server.

  Those are almost always hardware issues. Just before many of your crashes, your network cards seem to be bouncing up and down a lot: <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP <5>em1: link state changed to DOWN <5>em1: link state changed to UP Fatal trap 9: general protection fault while in kernel mode cpuid = 0; apic id = 00 Notice that the actual process on the CPU is always different for every crash. What is your config? I see references to a couple of different NICs, and a bridge.

  @NollipfSense : Found some posts elsewhere on the web that provided an explanation of why, sometimes, even ZFS can die. It has to do with the internal electronics of the disk drives themselves. Many provide caching, and some of those that do cache report a "write complete" operation to the OS when in reality the write is still sitting in the onboard cache of the drive controller. While the actual write happens a few milliseconds later, if power goes out at that very instant the data could in fact be lost. Many enterprise class disk drives have specially designed power storage capacitors integrated into their electronics for precisely this reason. They provide a half second's worth of power to allow flushing of any cache data. Cheaper consumer-level drives cut out this feature to save a few cents on the per-unit cost.

  Yup, I remembered now I was showing a technician how to install a production version of our pfsense onto a generic build. He resetted to factory default first and changed the interfaces so WAN was on a usb port. At the time I didn't think too much about it but it turns out to be a big head for me. @johnpoz I would so buy you a case of beer if I can. Thanks everyone for the inputs, I believe this is now solved.

  So a smart/managed layer 2 then ;) BTW, if your going to route and your wanting to access something on your downstream from a IP that is on your transit network you are always going to run into asymmetrical problems.. If you want to route to other networks on your downstream, then that needs to be connected to your upstream router via a transit network.. If you going to want to get to it from devices on your transit network.. Then you need to host route on them, or you run into the above asymmetrical problem. Connect your upstream to your downstream via transit network (no hosts on it) and your asymmetrical issues are gone Also if you created your SVI on the L2 that your 10 network is on, then its IP would be in the 10 nework.. If you created put the svi on a different L2, then you need to route it via a transit or host routes or your going to have the asymmetrical problems.

  Ok so you can ping out though? Try pinging out with large packets: ping -s 1000 -c 3 1.1.1.1 Try different sized packets to see if you really are seeing an MTU issue. Steve

  With IPAliases you can usually use either /32 or the correct subnet size. The important thing is you have at least one IP defined on the interface with the correct subnet in order to add the correct routing. https://docs.netgate.com/pfsense/en/latest/firewall/virtual-ip-address-feature-comparison.html#ip-alias Steve

  You could narrow that destination to just the PBX IP if that's the only thing you need access to in that subnet. Steve

  Yes, bridging the interfaces would allow the ISP router to 'see' the wifi subnet directly but it would still need an IP in that subnet to respond from which it does not have. With the outbound NAT rule as you have it you are passing all the wifi traffic across the LAN subnet which means, unless you have blocked it in pfSense, wifi clients will be able to access any LAN client which you might not want.

  Update from my end, I think I figured it out... After @chpalmer last msg, I went back to the "Hard disk standby time" settings and it was set to 180, which even if the systems was using the 180 mins it still didn't make any sense as to why is was spinning up/down so quickly. What I did is set it back to Always on and after saving and rebooting there are no more spin ups or downs. thank you.

  Just so you know there is no single sign-on style solution here. Clients have to login to the captive portal to access anything and then can have limiters applied against their traffic. Steve

  pfSense should not have a LAN gateway. If you have that set on the LAN interface remove it. Then go to System > Routing and make sure the WAN gateway is set as default. The fact you are able to reach the webgui shows it must be working to some extent. Steve

  Does it reboot because of some event? Do the logs show it rebooting or shuting down? Or do they just show it running then suddenly booting as though it was hard power cycled? The logs immediately before Sep 9 21:16:47 syslogd kernel boot file is /boot/kernel/kernel should show that. I assume no other VMs are rebooting at that time? Steve

  Yup. Upgrade. You will see that port 8080 traffic blocked in the firewall log though as I suggested some time ago. That will confirm the issue. Or just add the rule and restest. Steve

  Yeah its quite possible he asked the local IT support at his office.. And he brushed him off by dropping a name... Guess he is lucky he didn't drop say palo alto or the like as the name - or maybe this guy would be down 20k+ vs the 300 and in the same boat ;) Not sure where these users get the idea that security is easy, and or push a button. There is no device you drop into or in front of your network be it 300 or 10k in cost that makes your network secure - NONE... No matter what firewall you buy, no matter what software you run.. All just tools, how you use the tools requires atleast understanding the basic concepts of what the tool does and how to use it.. And you need to know which tool you need as well, or your going to be pounding on that screw with your 300$ hammer screaming this hammer freaking sucks!!

  @turnbulld said in Status and checks...: That's for sure the SNMP info. Noop. But the same source. It's Munin digging into the system using whatever is needed to present stats. The plugins are written in ... perl, C, bash, etc. @turnbulld said in Status and checks...: As with what you linked, there is nothing specific to the load balancer which I find a little odd. Probably because I do not have multiple WAN's, so I didn't activate 'load balance' related Munin plugins. @turnbulld said in Status and checks...: list of commands that are the source of the data on the dashboard. The code is the source - it reads like a manual.!! The widgets on the dashboard are just PHP files. Everything is in there - here /usr/local/www/widgets/widgets/....

  Hmm, only time I've seen odd behaviour a little like that was when the firewall could not open a state because all the IPs and ports matched. So as though it tries to open several SSH connections to the same internal IP using the same source and destination ports. Which would never normally happen with SSH. The client would normally use a random source port for each connection and the remote side NAT device would usually randomise it anyway. It would be worth running a packet capture at the remote side to see what actually happens though. Steve

  As chpalmer explained nicely - unless your network is different than what you have stated pfsense would not be involved in the conversations between the AP and ZD.. Devices on a network do not talk to the gateway (pfsense) to talk to other devices on the same network.. They only need to send traffic to the gateway, to get OFF the network they are on.. Since from your statement these devices are all on your LAN, pfsense is not involved in the conversation.. The only possible involvement pfsense could have is if the devices are using pfsense to resolve some fqdn to know where to send the hearbeat. But I have to assume they just talk to an IP, and not some fqdn that needs to be resolved. Only other involvement that pfsense might have, is if these devices are dhcp, and your dhcpd is running on pfsense.

  That file could only be stuck if somehow the notifyqueue_running lock is stale or not being released. Maybe something in your notification settings is broken and it can't get messages out.

  This is a great little tool for testing of multicast streams. https://support.singlewire.com/s/software-downloads/a17C0000008Dg7AIAS/ictestermulticastzip Simply launch the program one on the transmit side and one on the receive side and set accordingly. If multicast is making it then you will see the packets on the screen.

  @stephenw10 said in pfSense 2.4 wont reboot after interface removal - route cannot be added, network unreachable: Do those tunnels come up correctly after bootup is complete? If so that might just have to be considered log spam if those fqdns actually need to be resolved. Otherwise you could just use IPs there or maybe add static entries for them. The endpoints are on dynamic IPs, hence the need for hostnames. They resolve to dynamic ones. The tunnels come up, I would consider it log spam.
