New log type entry?

@marcosm said in New log type entry?:
It could also be useful to get a pcap of the dropped packet.
I will look into this tomorrow and upload it. 192.168.216.49 would be the destination IP and I would capture everything with this IP for some seconds.
-
A pcap on the external side there would see the traffic before the NAT translation so 192.168.216.49 would not be the destination at that point.
-
@stephenw10 On which interface should I capture, I thought on that where the log is from.
-
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.

@stephenw10 said in New log type entry?:
you should pcap on the external interface
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.
-
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?
-
@stephenw10 You mean a rule without a description? And what anchors? I can't follow. I am just a GUI-user.
-
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. -
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. -
@marcosm said in New log type entry?:
pfSsh.php playback pfanchordrill
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.
-
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:

@stephenw10 There are two on that interface.

Hmm, nothing there then.
It pretty much has to be some dynamic rule change.... Hmm -
Despite unticking "Packets blocked due to IP options" in the log-settings, those entries still come up.

@marcosm said in New log type entry?:
run "pfSsh.php playback pfanchordrill" for that
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: pfctl: DIOCGETRULES: Invalid argument pfctl: DIOCGETRULES: Invalid argumentLooks like 'pf' and 'pfctl' don't speak same language ^^
-
@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....
Edit: Not seeing that here:

@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...
