PfBlocker

ttblum

Hi, I meant to add that this only happens when pfBlocker is installed and active.

I have had two routers running pfBlocker that, when booted after a power outage, all inside hosts have lost internet access
after the router came back up.

I have searched around for an answer but I apologize if this has been answered elsewhere. My google-fu sometimes fails me.
I am trying to set pfblocker so that it's rules apply for all ports except a few that I have manually NATed. I can accomplish this beautifully for a short while by moving the selected firewall rules that are linked to my NAT entries higher in the rules list than the automatically generated pfblocker rules. This unfortunately then reverts back a few hours later to having the pfblocker rules at the top of the list again. I suspect it is reverting when pfblocker updates it's lists. Is there a way to either
1. Keep the selected NAT rules above the pfblocker auto generated rules even after pfblocker updates or
2. Have pfblocker ignore certain ports or
3. Accomplish my desired behavior a different way?

Thanks in advance!

Edit: Also, all these rules are in the WAN tab

Just a quick question on this..

with the block list I can see countries like china trying to send me spam emails (from looking at the logs).
And that's great! :)

But if I browse to a Chinese website does this mean that the pfblocker package won't block it as it has been initiated by myself?

Hi:

This is an excellent package. Thanks to developers for their hard work. BTW, I am encoutering the following:

06-24-13 10:33:54 [ There were error(s) loading the rules: /tmp/rules.debug:26: table name too long, max 31 chars - The line in question reads [26]: table persist file /var/db/aliastables/pfBlockerspamhausdshieldiblocklist.txt]

Which table is it referring to? And where to make changes?

pfBlockerspamhausdshieldiblocklist.txt is probably too long of a name for the list to work.

pfBlockerspamhausdshieldiblocklist.txt is probably too long of a name for the list to work.

Thanks. Changing alias to 'spammers' and rebooting worked (without a reboot, the config didn't reload, for developer's attention).

Hi Guys,

Quick question about pfBlocker regarding rules.
Under "Rules" there are all the pfblocker auto rules.

Its about when I change the order of blocking.
Lets say Subnet A is allowed to connect to asia and Subnet B is not. (See picture)

Every day, the rules are checked and reloaded, and Subnet A is set to the bottom of the list again.
So It does not have access to Asia any more. If I change it manually. This works fine for a couple of hours
until a filer or rule gets reloaded.

What can I do, so I don't have to change the order of the list everyday?
Hope the problem is clear. Thanks!

I configured gateway monitoring, but it didn't seem to help.

When the internet connection came back up, the filter reloaded, but pfblocker still would not let traffic through:

After posting a message about pfblocker not reinstalling in the 2.1 snapshot area I found this thread so I guess I'll just post a link to it here

Change the Pfblocker auto generated lists to 'alias only', and then manually create a firewall rule for each alias. Thanks to dokternoter for pointing this out before to me ;D

Thanks for your help! It works like a charm now!! Description name is important to get it working.

While at it, it'd be awesome if the custom set up lists did update on reinstall after snapshot upgrade.

Hello,
Running pfblocker 1.0.2 on a CARP cluster. The sync tab appears to be broken. Changes in configuration are not carried over to the backup system. Neither are new lists added, old lists modified. Used both sync interface ip and admin interface ip. Logs show this:
Master:
php: : Filter sync successfully completed with https://192.168.xxx.xxx:x.
Slave:
nothing, just a bunch of dhcp and dnsmasq entries.

The sync tab on the master has the sync ticked, contains the ip of the backup system, and the password is correct.
The sync tab on the backup has the sync NOT ticked, and IP is blank.

Thanks

It seems to think that 66.154.123.x is outside the USA, but it is with a hosting company in Los Angeles. Is this the right place to report this error?

Supermule

I think you need to find Marcello in here. I think he was one of the people behind PFblocker.

The contry ip blocklist was updated until the list got paid. There are other free good country lists but I'm still having no time to change pfblocker code to use a new list.

I've asked for donations to speed up update process but had no luck with it.

You can also workaround it by creating a new list with this ip/range and allow ir on pfblocker. This will be applied before pfblocker deny rules.

Maybe a dumb question… Does pfblocker block everything from a country you designate or does it only block unsolicited traffic?

Supermule

Everything…

Can we somehow track a specific IP and see what country CIDR it is attached to? I have a client that got blocked yesterday and I havent got a clue what country the IP is attached to?

kilthro

I dont know of an easy way of doing that besides searching the tables. However what I have done is identified the mistakenly blocked ip and added it to my allow list and all is good. Not the best solution but a work around so that they are not blocked.
