PfBlocker



  • Congratulations! Excellent work marcelloc!



  • Another question… am I supposed to see numbers in the packets column? Mine are blank... Thanks.

    Numbers will appear only when you have applied rules to aliases pfBlocker creates.

    Also post pfsense version and hardware used.



  • @marcelloc:

    I have the status showing up and running ver 1.0 pfBlocker on pfSense 2.0 x86; I don't know what else to tell you.




  • @mentalhemroids

    I guess the PfBlocker Widget counters are built by scanning the Firewall rule descriptions.

    When you use pfBlocker Aliasname in Firewall rules, you have to start the description with pfBlocker Aliasname for the widget to keep track.

    in your case "pfBlockerAsia bla bla lba'

    however, if you description end with 'rule' it would be recognized as auto generated and removed by pfblocker on save.

    @marcelloc:

    I've changed important note for better understanding.

    Aliasname something rule will be removed by package.



  • @RonpfS - Thanks for the tip… I would have never figured that out!  I at least have 0's showing up now; I'll see if they populate with numbers.



  • Sorry for that. I forgot to include this info in field description.

    It will be there in next release.



  • Hey all!

    I'm currently am running pfSense RC1 2.0 and Country Block. County Block works perfectly and is very easy to use for a novice like me.

    Is pfBlocker as easy to use as County Block to block IPs from specific countries? Are there any documents on-line I can read to learn how to use pfBlocker? I'm upgrading to the latest version of pfSense 2.0 next week and don't want to have any problems.

    Unlike everyone else here, I'm not a programming guru. I'm learning, but I have a long way to go!

    Thanks! :D



  • Wow - I looked at the screen shots and this is easy to for anyone to use. I'm impressed.

    A dumb question - are social networks like Facebook, Twitter, etc? Or is it something else?



  • take a look on ipblocklist website or any other that distribute lists.

    If you now socialnetworks ip ranges, you have an option to include in custom list.



  • Hi,

    installed the release totay on an Alix running nanobsd pfsense 2.0 - but get this:

    Nov 18 20:55:24 	kernel: pid 32813 (php), uid 0, was killed: out of swap space
    Nov 18 20:55:24 	php: : [pfblocker] pfblocker_xmlrpc_sync.php is starting.
    

    How do I get rid of the swap issue (RAM issue probably as nanobsd shouldn't swap - but the RAM is at 35% when this happens). Power LED of Alix keeps blinking.
    Only happens if this package is installed but then also if the only thing active is the TopSpammers list (deny inbound). All other disabled.

    Thanks!



  • Try to Increase Firewall Maximum Table Entries in system -> advanced



  • @marcelloc:

    Try to Increase Firewall Maximum Table Entries in system -> advanced

    increased to 1000000 and it happens still, in particular Reboot.
    Oh, and blinkled stops working as a service and cannot be restarted when pfBlocker is active



  • How many lists/countries do you have applied?



  • @marcelloc:

    How many lists/countries do you have applied?

    only pfBlockerTopSpammers, rest is disabled. May be a startup issue though as it gets calmer later (about 3 mins after router's webIF is accessible).
    Another thing I have noted is that blinkled can be started again (much) later, probably after the power LED gets released from its error blinking task.

    Raise the limit to 1500000 or 2000000.
    You may also have to raise the number of Firewall Maximum States

    Can you get boot log from serial console?



  • @marcelloc:

    Can you get boot log from serial console?

    Not easily as last time I got scrambled readings even though I used a null modem cable and 9600 8n1. I suspect the gender changer I had to fiddle in or the cable. Need to buy other cable I guess.

    Weird thing is that I never had this issue running Countryblock. Same system.



  • @RonpfS:

    Raise the limit to 1500000 or 2000000.

    …but I have only a small block list enabled anyway and my states are south of 200/23000 when this happens.



  • @ghm:

    Weird thing is that I never had this issue running Countryblock. Same system.

    Disable all lists and try a reboot.
    On nanobsd version somebody posted a error during boot on url tables.

    PfBlocker uses only native pfsense 2.0 functions to fill up aliases and create rules.
    unfortunately i have no alix box to debug it.



  • Anyone else having problems with lists?

    For some reason when PFBlocker is bringing in a list from a text file, it's making up it's own entries. Using the list for qwest ISP

    I've looked over the list a few times and can't find any typos. One of the ranges includes dell.com

    143.160.0.0/12

    No where is that defined in the list, but somehow it ends up in the table.

    I took a small chunk of the file and it looks like PFBlocker isn't correctly pulling in any of the addresses with only 2 digits in them.

    I'm not running 2.0 release yet… but I'm not sure if that would have anything to do with this.

  • Bman2121,
    When you pass a range, pfBlocker will find a CIDR that matches it.
    I saw in your list a realy large range( > /16).
    Change this list to a CIDR format and see what happens.



  • hankjrfan00,

    It's related to ip-blocklist package.
    If you had removed it, maybe you need to delete this remaining script.

    '/usr/local/pkg/pf/IP-Blocklist.sh start'

    Also look for ipblocklist scripts in /usr/local/etc/rc.d

  • Ran into problems today, rules were not applied correctly … anyhow.
    I removed pfblocker for my test, but the tables were still there.
    The widget was also complaining
    I removed /var/db/aliastables/pfBblocker* but I can still see them in Diagnositic: Table !

    How to remove them?

    So I reinstalled pfBlocker, create a table with the same name, with no list, nothing happenned.
    I added a list, the table was recreated ... fine ;o)
    I I renamed it to the second table, table is renamed ok.
    Now I delete the table ... nothing happens, table still present
    I disabled pfBlocker, all the tables were gone  :D
    I enabled pfBlocker, the old tables were finaly gone.

    So I created another table, I deleted it but the table remain available until your click Save in Firewall: pfBlocker: General
    Do we need a Save or Apply changes button under Firewall: pfBlocker: Lists?



  • How/where could I apply a pfBlocker list to filter inbound traffic on a NAT-PMP port created by miniupnpd?



  • @RonpfS:

    How/where could I apply a pfBlocker list to filter inbound traffic on a NAT-PMP port created by miniupnpd?

    Try first on floating rules and go testing access with tcpdump on console.





  • Thanks for your contribution.

    Do you know how often its Updated?



  • I don't know how often the advertising blacklist is updated, it doesn't seem to be very effective. I'm the "cup half full" type of person so I block those IP's anyways.

    As to the known malware IP's, I believe from looking at the commented-out time stamp within the files they look to be updated daily.



  • Can somebody please tell me why PFblocker widget isn't showing all my block lists as being blocked?

    Specifically the Russian Business Network Malverisers IP list is working however their CI Army list is not…. but the IP lists are of the same structure.

    Working: http://rules.emergingthreats.net/blockrules/rbn-malvertisers-ips.txt

    Not working or showing on Pfblocker widget: http://www.ciarmy.com/list/ci-badguys.txt

    Please help!



  • Check first in diagnostics tables if this list was filled up.

    Then check rule description for this alias rule.



  • @marcelloc:

    Check first in diagnostics tables if this list was filled up.

    Then check rule description for this alias rule.

    Can you please explain this in further detail? I don't see alias rules for these lists, shouldn't they have been automatically made?



  • The pfBlocker is great! It's easy to use and very effective! Thank you!

    I have 2 dumb questions.

    1. I would like to go view the stats of what is blocked by pfBlocker. I saw your screen capture at the beginning of the pfBlocker forum. Where or how do I access this?

    Again, great work!



  • @hankjrfan00:

    I am getting this in the System Log.  Any ideas?

    I might make the suggestion that pfblocker uninstall runs a script to clean it out of the packages directory (and any directories it leaves behind there). While one could go to do this manually (especially if you had country block before), it makes more sense to remove the scripts and files it creates there so a reinstall will keep this type of thing from happening.

    If not a BIG FAT STICKY that tells people what they need to do would probably keep these types of messages from having to be posted.

    Essentially, manually remove:

    /usr/local/www/packages/pfblock* and the other two related directories, especially the one with the startup script. It doesn't unintall cleanly or reinstall cleanly.



  • Grazman,

    It's related to ip-blocklist package.
    If you had removed it, maybe you need to delete this remaining script.

    '/usr/local/pkg/pf/IP-Blocklist.sh'

    Also look for ipblocklist scripts in /usr/local/etc/rc.d



  • The pfBlocker is great! It's easy to use and very effective! Thank you!

    I have 2 dumb questions.

    1. I have Russia blocked but need to allow for the access to my network from the IP 213.238.8.10. I looked up the CiDR for it. How do I enter the IP to allow it past the Russia block list?

    Create a new list, choose action allow inbound and paste your networks in custom list.



  • So you're saying my new list will over ride the other lists by default?

    Also, what format to I put the IPs in? Is it listed as below?

    213.238.8.10/32

    Sorry to be so stupid on this.

    Thanks!



  • whitelist(allow) rules are applied before blacklists(deny).

    the custom list is in CIDR format, so if its only one ip address 213.238.8.10/32 is fine.
