My issues predated 2.4.5, I've since updated from 2.4.4 to 2.4.5.

And has that made any difference?

I've finally gotten OPNsense setup correctly. I'm going to try that tomorrow morning. Also just preparing a 2.4.5 install - will try that as well.

Disabling Bogon's and Gateway Monitoring helps somewhat - in that when the packet loss occurs, it subsides much quicker (which ties in with the link I sent about the firewall rules resetting). However, the underlying packet loss issue is still there.

I'd like to try router mode during a work day - I suspect it too will have some issues. The problem is my network setup at home uses the same subnet as the Virgin router, and it's not possible to change the virgin config!! Reconfiguring my own subnet would be very time consuming (but will bite the bullet if neither OPNsense nor 2.5 solve the issue).

Cant believe how much time Ive wasted on this crap.

No it didn't make any difference.

Thanks for the feedback.

I did manage to get 2.5 working briefly, but it's sooo flaky (as expected of a beta), that I couldn't live with it.

I'm running opnsense now so will feedback whether the issue reoccurs.

Used OPNsense all of today and hit the issue only once. Certainly positive, but will run for a few more days before reverting to pfsense to test that again (in case Virgin have fixed something on their side).

Glad I haven't seen this, my appliances CPU runs at unholy temperatures at 100% usage, but that only happens briefly when fiddling in the UI.

I've been testing this for a number of days now.

I should say I've had a virgin engineer round too who added a noise suppressor and also replaced a section of cable which had multiple joins with one new length. This has no doubt improved things somewhat.

Ran opnsense for a couple of days and had one, maybe 2, instances of packet loss. Switched back to pfsense and things have improved, but still getting far too many spikes.

Disabling the bogon network check means I no longer get a complete loss of connectivity. Only a spike in ping and packet loss for about 15 seconds or so.

No conclusions yet, but a picture paints a thousand words.

Graph from yday (24th May) where I switch back to opnsense at 3.30pm:





This graph from today shows my switch back to opnsense yday at 3.30pm:


Clearly opnsense seems to be far, far better.

Interesting, clearly something's amiss with pfsense then.

From what I've read, it seems to be a bug in the FreeBSD version they are using so not a quick fix.

Could you point me to where you've seen this?

I'm running OPNsense 20.1 (based on FreeBSD 11.2) which is fine.

PfSense 2.4.5 is based on FreeBSD 11.3. Is this the version affected?

If so, rolling back to 2.4.4.-p3 may resolve, as it is based on FreeBSD 11.2.

As mentioned on the previous page https://redmine.pfsense.org/issues/10414 although looks like they have a temporary fix now.

Thank you. I missed the disable smp workaround. I tried the bogon / firewall entries, and it did not resolve the issue for me.

Looks like 2.4.5-p1 is days away from release which should resolve this.

Be interesting if it resolves mine, as my issue existed prior to installing 2.4.5

I tried disabling smp and also reducing my vCPU count to 1.

I ran the tests in the last post here: https://redmine.pfsense.org/issues/10414, and I dont see a CPU spike. Which confirms that the issue they describe has indeed been solved. But...

Within one hour, I got a ping spike / packet loss and gateway disconnect. So I dont think this is the same issue.

I've now reverted back to OPNSense.

Will try once more when 2.4.5-p1 is released, but not hopeful.

The thing with pfSense is, if it sees a big enough ping spike/packet loss it will disconnect the gateway assuming its gone down.  This behaviour can be tweaked in System -> Routing -> Click the edit icon next to the default gateway and expand the Advanced options.  You're looking for Latency thresholds and Packet Loss thresholds.

This is why I do not have gateway monitoring action enabled at all for my VPN Clients nor the LTE connection, as these things regularly have packet loss and latency spikes, causing the firewall to restart.
