Firewall Rule Numbers
-
Yeah not every rule shows its description as i have them in column view but i still get rules that i would have to work out which rule caused it. If it just displayed the rule description for all rules in column or second row view it would be much better.
-
Perhaps post a screenshot? Does not happen here.
-
My firewall log shows both the rule description and rule number. Only time I've know it to show just the rule number is for firewall rules that are disabled or deleted.
-
The description is shown where one exists. If you have a number only, it should only be because it's being logged by a user-defined rule with a blank description. Or possibly the deleted rule scenario NOYB mentioned if you removed some rule(s).
-
Just verified that a disabled (not deleted) firewall rule will also result in the description no longer being displayed in the firewall log. Upon re-enabling the rule the description is again displayed in the firewall log.

Well yes, cannot get a description where it doesn't exist in the active ruleset. ;)

Ok thanks I've toggled column view a few times and it all seems to work but they root of my problem seems to be just one rule that will not show a description. All the rules on the OPT1 interface have a description but i think i will just have to work it out manually which was what i was hoping to avoid.
Also at the command line running pfctl -vvsr give mess this relating to that number
@40(1000000114) block drop log quick inet proto tcp from any to any port = 0
[ Evaluations: 5321224 Packets: 4737 Bytes: 284220 States: 0 ]
[ Inserted: pid 73290 State Creations: 18446735277732176120]
@41(1000000114) block drop log quick inet proto udp from any to any port = 0
[ Evaluations: 5316129 Packets: 4737 Bytes: 284220 States: 0 ]
[ Inserted: pid 73290 State Creations: 18446735277732176096]Although I'm no clearer where this rule has come from.
Thanks for replies.

Well that does not have any label, it's this stuff in https://github.com/pfsense/pfsense/blob/master/etc/inc/filter.inc#L3157

Not quite sure i want to do that yet but will just know that this particular rule number relates to the default rules and not worry about it anymore.
Thanks for all your help.

It's been merged to 2.2.4.

Question slightly OT: Is it good practice NOT to log packages blocked by the default deny rule (Settings, first option under "Log Firewall Default Blocks"?
-
Hmmm… depends on how much noise you like, or what you policies are, or whatever. Wouldn't say there's any "best practice" here.
-
Im still trying to work out the best settings since I've only been using pfsense a few months so I've left logging on most things so i can see whats going on unless i really really don't want to know about something.
-
I dont suppose you could do the same for UPnP rules as well?
Thanks

(This is an attempt by me to not clutter up this forum by repeating the same question, but instead information to an already existing thread if that is similar. If I did wrong by doing that I apologize).
I have the same problem as the OT. I suddenly have blocks in my FW log without descriptions. Clicking on the red cross doesn't show any other information.
(I do know this happens when you disable logging for a FW rule which was previously enabled, but I did not do such a thing at all).
Is there a place where I can find all the rule numbers together?

Bonus: this description isn't right. MULLVAD is a separate interface, it is not the interface VLAN40:
Thank you for help

cat /tmp/rules.debugLook at the tracker. -
Thank you. I also discovered

rules.debug is the best place to get the configured rule set all in one place. It is usually one of the first places I go when evaluating a status output, depending on what the trouble is.
I never look at the rules in the config.xml. rules.debug lays them all out for you in a readable format.
