@JKnott thank you very much for the information and insight greatly appreciated

@stephenw10 said in pfsense drops wan (PPPoe) when using speedtest.net: I assume the I Yes this is VDSL, the ISP device is in bridge mode and pfsense does PPPoe.

FeedBack : There is no hardware failure related issue reported in System logs. I am monitoring the system remotely. CPU usage showing 7%-8%. Memory usage is 27% (out of 4GB RAM). Approx 50-60 users are connected. Waiting for the problem to reoccur.

@stephenw10 - Thanks Steve! I've added those 4 addresses as "other" and I'm sure that will come in handy later on when I need to use those addresses for other purposes. Right now I'm using them only to temporarily solve a strange problem I'm having with two websites not responding to two of my users unless their from address is a different address then my primary one. My ISP is trying to run down this problem but for now this 1:1 NAT workaround is getting the job done. Roy...

I think i have narrowed it down. Your questions about my hardware made me look into my switch a bit more. It is "passively" cooled but as it is in a cabinet it seems it isn't getting enouch airflow. I turned it off for a period of time and back on and i'm getting good speeds with no packet drops. I have already ordered a fan that i can put inside. Thanks for all the help!

@serbus I have a APC UPS and then a APC 7900 PDU connected between them. I do have NUT setup and appears to be working right now. However, next time I am home I am going to manually cut the power and test just to double check. So far so good, as it has now been over 3 hours without a reboot since I forced an automatic system check on reboot. However, I did make some other changes (disabled PIMD, etc.) that may affect the frequency of the reboot. I am fully backed up and hoping for the best, but prepared for the worst. I will reinstall from scratch and restore from backup once I am back on site. I also plan on enabling RAM disks now as well.

@qtwrk Since wired devices work, it's not a pfSense problem. IPv6 relies on multicasts for several functions. As I mentioned, RAs are used to provide address info. All a router does is send out the multicast with the appropriate info. About the only thing that could cause a problem would be bad info. However, that would affect all devices, not just WiFi.

In outbound NAT rules, i specified the Interface address as VIP address, [image: 1595865822151-a19f0df6-9812-48dc-bbeb-104711785854-image.png] Now it works! Solved!

Thanks. I am running fsck now through ssh 5 F.

My configuration is pretty basic. Just VLAN interfaces set as downstream so that pfsense acts as the IGMP Snooping querier for the switches. I don't actually require mcast routing. Anyways, I manually copied over the config file from a 2.4. 4-RELEASE-p3 box and started IGMP proxy from the CLI. Since then its been working fine and I can make changes from the GUI.

Yeah, you need NAT to reach anything from an internal non-routable IP as you found. Try running at the command line: pkg -d update What error does it report? Steve

Did you actually see a crash report? Normally indicated by an alert i the GUI after you reboot. If not what exactly happened? pfSense became unresponsive? Even at the console? Torrents typically cause problems because the open a lot of states. That can exhaust something on smaller pfSense boxes though just one torrent client is not normally anywhere near doing that. Check the monitoring graphs (Status > Monitoring), look at the state usage in the time leading up to the incident. Steve

I no issues with either of those. There will be some variation in your own switch. Just remember that you are removing pfSense as the filter between the VLANs. Any filtering you need there now has to be done using ACLs in the switch. That also means you now have two places to check for filtering rules when troubleshooting so be aware of that. Steve

FYI...Turned out that my 24-port switch was bad. New switch = No Problems!

You can set an expiry date for local users sure. https://docs.netgate.com/pfsense/en/latest/book/usermanager/user-management.html#adding-editing-users

@feedyourtv Most probably a hardware issue. The fault will propagate sooner or later. Usually is due to faulty decoupling capacitors on the motherboard. To say that ashrock boards are problematic is as invalid as by saying that windows never blue screen. If it was a software issue, this board would be full of complaints, rest assured. Have fun, as long as it works out for you this way :)

@jim82 said in WAN looses connection randomly with 24-36 hours - tried everything: 14 days after and my connection is rock solid. Thanks for your help.

@netblues One other thing, that current IP changes daily when SLAAC and privacy addresses are used. I agree firewalls should be used, but there are some things in IPv6 that make it safer than IPv4. Also, IIRC, pfSense and just about every other firewall defaults to deny all, so unless the OP actually did something to leave it wide open, he should be OK.

Ive been running a clean install (i.e not an upgrade of 2.4.4p3) of 2.4.5p1 with a minimal restore of config (too many rules to recreate from total scratch) for a few days now and gradually things have worsened. The culprit is pfctl which can be seen consuming 100% of CPU in System Activity. I have pfBlocker installed but have it set to run cron once per day at 3am and it doesnt appear to cause the load. I did notice on day 1 of running a clean install that the increase in latency occurred at exactly the precise time /usr/bin/nice -n20 /etc/rc.update_urltables was scheduled to run. Rebooting seems to reset things to some degree but at this point I suspect I have to roll back to 2.4.4p3 as this latency is making video conferencing virtually impossible.
