PfBlocker

If it's going to be a major pain to do, perhaps it wont be worth it.
Just looking from the standpoint of the end user, I think it would be very helpful is all. If I can help in any way let me know, will be glad to do so.Pfsense is not for end users, it's for firewall admins or small networks admins. You must know about tcp/ip and what you need or want in a firewall.
If we do a chart, the next question will be about someone that followed that chart and is not happy about the results.
It's unnecessary in my opinion.
-
I don't think any amount of experience or knowledge of tcp/ip would give you a good idea of the amount of system resources consumed by firewall rules. That is more dependent on the specific software, and combination of software. Since pfsense has a common software platform with only minor variations, I think a chart would be somewhat accurate, but it's of course up to the user to use their common sense.
If the consensus is that it's unnecessary, that's fine. I don't agree that a working knowledge of tcp/ip has anything to do with the subject, however.

I agree with marcelloc. Creating a chart is unnecessary a will not reflect real world scenarios on a real world budget for home use. It would be extremely difficult to account for all platforms that pfsense is compatible with.
Kamel,
marcelloc is right. This package was created to assist networks admins and professionals. Having performance issues at home on is not a concern. The fact of the matter is that all performance issues can be solved with hardware. Every single IP added to a list consumes RAM. Packets entering and exiting the firewall requires processing power. Furthermore, pfblocker uses native pfsense software and knowing this you can conclude that if your firewall isn't performing at the level that you need then it is a hardware issue and not pfsense at fault.You have some good ideas but you're missing the fundamentals. pfsense does appeal to and is compatible with many platforms but when it comes to the best performance many platforms will not perform better than other platforms.
Also you don't need to know the inner workings of TCP/IP to work with pfsense but if you're going to manage pfsense in an environment where pfsense thrives then you better know everything about TCP/IP and so much more. marcelloc was using TCP/IP as an example of what a network administrator would know at a minimum to understand how to properly manage a firewall since this package was created for network administrators.

Forgive me if my comments seemed a bit tasteless. I got the impression marcelloc was insinuating that my abilities were insufficient. I know I shouldn't have so I apologize for that.
I still believe it would be a good idea (and should be relatively simple to add) to check if there are enough firewall entries available for the amount of rules pfblocker applying before you submit. This was actually my primary concern, the idea of system resource usage was only secondary to this.

I'm not insinuating anything. I'm here to help the project just like everybody.
I'm sorry if my post sound offensive. It was not my intention.I'm improving some help messages on package gui to help even more admins.
PfBlocker checks the ammount of entries in a list before apply, but it Does not sum all lists. I will try to include this in version 1.0.1. You maybe still getting this error if you have many rules or aliases. Just like the chart, we can get close to all situations but not all. -
I have two pfsense v.2 instances, i386 (2 different networks). pfBlocker has been installed on both ones.
It works just fine on one instance, and doesn't work on another - it doesn't block anything at all.
I have disabled all existing firewall rules, have checked tables in Diagnostics->Tables (they exist indeed) - everything looks just fine.
But when trying accessing internal network (WAN interface was selected for inbound rules), I'm not being blocked from the target
network which is supposed to be blocked. Tried adding custom rules list - no luck, added a country to block list - no luck to see it working.
The only difference between these 2 instances is that on pfBlocker has a combobox menu selector, another one has tabs.
Both were installed from GUI. I'm totally lost. Any ideas how to check why it didn't work ? -
make sure you are using the same version on both.
gui was designed to fit tabs and prevent combolist.
also check pfblocker applied rules on wan or lan.
you need at least one rule on interface you want to apply rules.
if you don't mind, post your rules screenshot.
note: pfblocker use native pfsense functions to help admins. So if you have rules not working, check what is going wrong with your box.

You maybe still getting this error if you have many rules or aliases. Just like the chart, we can get close to all situations but not all.Increasing my firewall rules limit worked fine and it's fast with no issues (assuming I disable some other services to reduce my RAM consumption). I will admit, it was a bit of a pain figuring out what was wrong at first. Even many searches going by, it seemed people were referring to things like memory etc. I hadn't realized the number of rules in the blocklists were impacted by the number of firewall rules or I would have known what to do immediately.
In any case, thanks for that – I think it will be a simple enough but helpful addition. I know for me personally, I'll never make the mistake again :P

This may sound silly, but do you have any catch-all rules that might be allowing the traffic to pass before the pfblocker rules have a chance to block it?
-
Just loaded pfBlocker - initially it seemed to be just what we needed - (had a recent flurry of far eastern IP addresses appearing in the logs) - but whilst it works it seems that SquidGuard has stopped working.
Just me or have I missed a thread somewhere?

For wan interface I disabled all rules, but not pfBlocker test one.
Don't have any floating rules for now. I'm trying to have as clean as possible system for testing. -

1. I'm sure.
2. Can see only combobox (uninstalled, rebooted, cleared config.xml before rebooting - no changes.)
3. See my screen shots
4. I have one (the same) rule in both cases.
5. Attached.
6. Where can I read how to use pfsense native functions ? I'm a pfsense novice.Thanks for the help.

Since I installed pfBlocker, Aliases seem kind of wonky.
I've searched the thread+forum, but couldn't find the right answer to my problem.If I create an alias in Firewall -> Aliases; the alias doesn't show up in the dropdown list (in Rules -> Destination -> Address field).
Only the Aliases created in pfBlocker are available.
If I type out the Alias Name (correctly) I get:
I've tried rebooting pfSense after creating the Alias but it didn't help.
Am I missing something? -
slarg,
I think your are not on latest version, it should be
2.0-RELEASE
built on Tue Sep 13 17:05:32 EDT 2011update it to release version, then test again.

LinuxTracker,
Port alias must be applied on port field, not in host field. ;)

Yep. You is right on, you are.
I sho nuff stepped into that one.

Why does pfBlock create duplicate rules (or at least they look like duplicates to me) and where does it log to? The dashboard widget is showing an increase in packet count but I seem unable to find out what is causing it.

pfBlocker package log to Status: System logs: System
Just click Enable Logging under Firewall: pfBlocker for list action that are NOT Alias only.
The pfBlocker auto generated rules will log events under Status: System logs: Firewal.When you use a pfBlocker Alias in your custom Firewall rules, select Log packets that are handled by this rule
You can see more details in the firewall logs when you enable Show raw filter logs under Status: System logs: Settings

*** Thanks for the info
Just click Enable Logging under Firewall: pfBlocker for list action that are NOT Alias only.
*** Already set

*** Still no sign of anything that matchs
Also why are all the rules duplicated?

Can you take a screenshot of this duplicates?
*** Still no sign of anything that matchs
It will log as firewall rules, no extra info about pfBlocker package.
