New log type entry?

stephenw10

Yes you should pcap on the external interface but you will need to filter by something else because 192.168.216.49 won't be present on those packets at that point.

I filtered only for TCP. Sry for it being that big but I had no success provoking it with just light traffic... Included is the log entry and some pfctl -sr.
I hope you guys will find the secret rule.

stephenw10

Thanks.

To be clear though do you have any rules in your ruleset that do not have an ridentifier value set?

Within the anchors maybe?

Bob.Dig

@stephenw10 You mean a rule without a description? And what anchors? I can't follow. I am just a GUI-user.

stephenw10

I mean in the output of pfctl -sr. In your txt file that is grep'd for ridentifier lines only. A rule that doesn't have an identifier won't set it on the state and could produce logs like this.

marcosm

I didn't mean to leave the grep part in my previous example . IIRC that won't show anchor rules so you can run "pfSsh.php playback pfanchordrill" for that.

That lists no rules.

Looks like having a block rule on that interface is "fixing" it for my eyes.

That turned out not to be the case, still seeing these log entries.

stephenw10

Ok and your ruleset doesn't have any lines that don't have an ridentifier?

For example this test box doesn't have any that might block traffic:

Hmm, nothing there then. It pretty much has to be some dynamic rule change.... Hmm

Bob.Dig

Despite unticking "Packets blocked due to IP options" in the log-settings, those entries still come up.

Not related, just for the the record :
pfanchordrill breaks when the captive portal is used :

[25.07.1-RELEASE][root@pfSense.bhf.tld]/root: pfSsh.php playback pfanchordrill

cpzoneid_2_allowedhosts rules/nat contents:

hostname_0 rules/nat contents:

Looks like 'pf' and 'pfctl' don't speak same language ^^

stephenw10

@Gertjan Hmm, when you see that it's almost always because it's pulled in something newer. Or not rebooted after an upgrade. So some mismatch between kernel and world. But let me check....

@Bob.Dig said in New log type entry?:

There is no rule at all on that interface.

This feels like a clue. What is that 'interface'—PRIVVPN—then? What's it do? What's it for? What kind of traffic is supposed to be passing it, from and to where?

Notice in OP how the oldest packet is apparently a TCP packet without any flag set, no source/destination ports logged? But then the next packet is an ACK in the same direction, ostensibly from a webserver, and this time with logged ports?

And this...

Noop. I should be on 'Release', not RC or beta.

I'm, imho, on a rock solid 25.07.1. I saw the same thing happening on (several ?) versions before.
I've installed '25.07.1' clean and it was on of the first things I've tested.
I've written about it in the past, in the captive portal forum (I'll look it up : edit : here it is).

I use(d) this : Troubleshooting Captive Portal.

Even when I de activate the captive portal, I'll keep seeing this :

[25.07.1-RELEASE][root@pfSense.bhf.tld]/root: pfSsh.php playback pfanchordrill

cpzoneid_2_allowedhosts rules/nat contents:
pfctl: DIOCGETETHRULES: No such file or directory

hostname_0 rules/nat contents:
pfctl: DIOCGETRULES: Invalid argument
pfctl: DIOCGETRULES: Invalid argument

If I recall well, restarting pfSense without the portal will solve the issue.
Re activating the portal will bring the issue back.

I changed mine, to look like yours. Let's see, if it has any positive impact.

Btw, your questions have been already answered here, it is a WAN-type interface and with that, it can have no rules and be perfectly fine.

Any thoughts provoked there? I don't see that as having been addressed anywhere.

All due politeness—but a jacked-up system has the potential to 'trigger' jacked-up logging...
