pfsense short cpu load hang
-
i found something
when the problem apears my wan interface is down and theres "autoselect" standing
its running on 100baseTX, my modem is max 100mbit rj45
-
Who or what takes the WAN down ?
Check logs, the answer is there.
Example : if dpinger, the gateway monitor starts missing a lot of pings, it pulls the plug = restarts the interface.
And let me guess : when you de-*activate snort and/or pfblockerng, the problem stops ...

What version of pfSense are you using? If it's 2.4.5 there's currently a known issue where anything that causes pfctl to be called (such as openvpn restarts) to chew all CPU, with the knockon effect of packet loss and latency.
Current fixes appear to be:
Roll back to 2.4.4p3
If Virtualised, reduce your system to 1vcpuNetgate are aware of the problem and are, I believe, working with the freeBSD devs to come up with a solution.
There's a number of other threads in the forum about this problem. Hang in there and hopefully will be fixed shortly :)

i looked into the system logs, this happens
@muppet its a bare metal device, not an vm, its running 2.4.5, but i think befor update, the problem was allready there, is my nic maybe bad? since its going to "down", and then again to "up"

Yeah, go for the bad NIC - check / exchange both sides, or bad cable.
-
@fischstäbchen Yes I'm very sorry, I should have read where you said Interface flapping. My bad, I'm sorry.
-
It's a possibility, you have to check to be sure first.

@Gertjan @muppet
i changed the wan cable, insert a switch in the middle, to see if the net is going down or the ethernet adapter, it looks like my USB Ethernet Adapter is the issue, my question is now, is there a usb ethernet which works with freebsd and pfsense to get this again fully working?
i changed to an HP Probook 450 G1 currently, but didnt helped, so its my adapter, its an ugreen AX88179 USB Adapter
Its wall mounted, so i need something little but still powerful enough

At the end you mention you use one of those things ?

That the one million $ question.
Many have asked this one.
Answers are very rare. FreeBSD strong point has not the word 'USB' in it.
Some exist .... You're good for the Find fucntion of the forum.Btw : you also found out why pfSense is rarely if never used on a portable PC.

Zotac Zbox CI329 Barebone nano mini-PC, would that be a good option for pfsense, Intel N4100 quad-core with two gigabit nics.
-
I think this is a good choice for SOHO environment: https://www.pcengines.ch/apu4d4.htm
There is also some level of forum support -
