Do you have any Virtual IPs? And are you using IPv6?
Could you post a screenshot of the VIP addresses and masks?

Hi stanthewizard,
I took a look at the code for the Alerts tab in Github and it does not contain my patch for this issue… I must have not added those changes to the previous Pull Request. I will get that fixed in the next PR.
You mentioned that you did a work around? If its still not working for you, let me know and I will get you a patch for it. (send me a PM if you can't wait for the next version) :)

I can wait no issue
I'm using the workaround you gave me :P
PS: still the footer is out of line

In response to a pm I received about:
@azurata:I was waiting the pfBlockerNG new version to do adblock using the unbound, but until it's released I add a VIRTUAL IP to the Lan interface, made a script to convert http://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&mimetype=plaintext to unbound advanced rules to redirect to the VIRTUAL IP and setup a nginx to listen to both 80 and 443 on the VIRTUAL IP and respond to all with "204 No Content". For my surprise is working better that I was expecting.
made a tutorial, Simple adblock using unbound and nginx

Just did the update to 1.08 and got
[ There were error(s) loading the rules: /tmp/rules.debug:23: cannot load /var/db/aliastables/pfB_Africa_v4.txt: No such file or directory - The line in question reads [23]: table persist file /var/db/aliastables/pfB_Africa_v4.txt]

Is it possible to select which internal IP addresses pfBlockerNG gets applied to? I want to be able to say use a blocklist for a specific internal device and all other devices will not be blocked by the blocklist

Hi meruem,
You can define the alias using an "Alias" list action (ie "Alias Deny"). This will allow you to create manually defined firewall rules with your specific requirements.

I see that pfBlockerNG added the IPv4 alias (which contains the large blocklist) I created to the firewall rules (action: block). I'm not sure how to only apply that firewall rule to a specific internal ip address(s) though. I tried editing the rule added by pfBlockerNG, and set the destination to a single internal IP address, but the rule is still being applied to all internal devices on my network
-
When you create the Alias, Set the "List Action" to "Alias Deny"… This way it will not create any Auto Rules. You can then create a new manual Firewall rule with your custom settings and then associate the Alias in the Rule.

BBcan177,
That worked perfect, Thanks.
In addition to the WAN incoming blocking, I created a firewall rule for LAN outgoing blocking. Firewall => Rules => LAN => Block => My Internal IP's Alias (Source) => External IP's Blocklist Alias (Destination) to complete the "no contact whatsoever with the blocklist IP's" thing I was going for
Also, I had to go to Diagnostics => States => Reset States. Because I found out, through testing, any established states before firewall changes do not adhere to the new firewall rules until the state has been removed from pfsense (either naturally or manually). I recommend this step to anyone doing the same thing as me, to complete the process
This is powerful and flexible. Now my blocklist(s) are not globally encompassing my entire network, and I do not have to tightly couple blocklists with client side software programs

Maybe somebody can give me some direction to a correcting an error. Whenever I attempt to open pfBlockerNG > Alters tab it stalls and eventually displays a blank white page. Going back to the default home page (index.php) an alert is displaying "pfSense has detected a crash report or programming bug. Click here for more information.". Opening the crash report page displays the following

Hi BitechBob,
Can you edit the file /usr/local/www/pfblockerng/pfblockerng_alerts.php
and comment out line #703
$pfb_local = array_merge (subnet_expand ("{$list['subnet']}/{$list['subnet_bits']}"), $pfb_local);There will be a fix for this soon… This is only an issue for systems that have a large CIDR range in a VIP address so this only needs to be edited in this scenario. You might notice that the Src/Dst Columns will not show the "!" and "+" icons on the Local IPs if alerts include any of these VIP addresses.
If you need any further help, send me a PM.
Thanks!

OK, I have a stupid question. I have to whitelist an IP of an FTP server in India. I have pretty much everything blocked except for traffic in the US and Canada, mostly inbound only. For the 'Top 20' tab, I have deny both. For some reason, this server's IP is on the top 20 spammer country list.
I have setup a whitelist in the ipv4 tab and have it pointing to a txt file on my pfsense box. In this setup, I have "Permit Both" for the "List Action".
So now my question. By doing this, am I allow this IP to bypass all the other rules on my firewall, or does pfsenseng permit this IP first and then flow it through the other rules? So, for example, if I allow this IP, will netbios traffic from this IP still get blocked because I have a firewall rule that blocks netbios inbound?

Thank you for the quick reply!! I performed the edit but then for the same process I now receive
Parse error: syntax error, unexpected '}' in /usr/local/www/pfblockerng/pfblockerng_alerts.php on line 704
It's no big deal and I can live with it until the next release.
Again THANK YOU!

Hi wiz561,
I have posted in this thread about blocking the world, and allowing a few Countries.. You should reverse this approach to Permit a few instead.. You can read this thread for more details on that.
pfSense is a stateful firewall by design. So if you do not have any Open ports, its already implicitly deny on the Inbound. So any rule on the Inbound is a waste of processing time etc…
If you have a few open ports, you should consider creating an "Alias Deny" Rule for just those ports on the Inbound instead of blocking all other ports that are already going to be blocked by the implicit deny rule.
For a 'Whitelist', its best to make it an "Alias Permit" and only allow a certain port and the specific IPs you want to allow inbound in the Firewall Rule.
The way you have it now, with a "Permit Both" will bypass all of the other rules and is not safe.

Sorry about that… try this: You need to add the part $dd = 1; along with commenting the previous line above.
elseif ($list['type'] == "single" || $list['type'] == "network") $dd = 1; //$pfb_local = array_merge (subnet_expand ("{$list['subnet']}/{$list['subnet_bits']}"), $pfb_local); } -

No rush I can hold off until the next release.

Thanks for the information. I went back and modified what I did so I could undo it, exclude the country for now, and will have to figure out how to properly do it. I tried to create an alias and go that route, but it wasn't working properly for me.
I'll dig through the thread and see if I can find the proper way to create whitelists. Thanks for the response and the information about it!
