PfBlockerNG
-
Hey everyone,
My apologies, but I'm just not getting how to make the ipv4 lists work.
I have an i-blocklist subscription and I enter in the list and can see when I update that it's finding updates, but I don't see any alias created or any rules made outside of the country blocks. Should I see any firewall alias's or rules after entering an ipv4 list/s?
I've done my fair share of looking through this thread and I still can't figure it out. Any help would be greatly appreciated, even if its "no you're doing it wrong".
Thanks,
Tom

Hi Tom,
What does the text say just below the "Save" button :)
Goto the Update Tab and click "Force Update".
Also instead of blocking the world, best to permit the ones that you want. I've written about that in this thread and in Reddit.
-
I do the force update, but it doesn't seem to have an effect. Every time my tab (Chrome) will show the spinning icon, and eventually I will get an nginx timeout.
-
What does the pfblockerng.log show? Goto the Log Browser tab to view it for clues. Never seen this issue before.
What pfSense version? What kind of hardware? If your blocking the world, you might be blocking DNS servers (if using the resolver) and IBlock urls might be in other Countries.
-
Only log that will show is the pfblocker log, all other logs show failure to read.
I'm on 2.3 release and the hardware is a Dell Optiplex 960
https://www.dell.com/downloads/global/products/optix/en/desktop-optiplex-960-technical-guidebook-en.pdf.
-
Are there any more lines in the pfblockerng.log file? Can you scroll down to see the end of the log? Those entries are ~24hrs ago. Did you select the Interfaces in the General Tab?
-
Thats all there is in the log. Entries are recent, at least in my timezone :) Interfaces are configured per the screenshot below.
-
You clicked "Floating Rules". So any firewall rules will not show in the wan/lan tabs. Goto the floating tab to see the rules. If Cron is running. You will not be able to Force Update till cron completes. You should be able to hit "view" in the update Tab while Cron is running.
-
Here is what I have on the floating rules. Should there be additional rules for ipv4 lists?

Hi,
I think I found the reason why DNSBL wasn't working for me when using together with squid and .PAC file.
DNSBL creates to NAT rules to redirect ports 80 and 443 to the internal server on IP 127.0.0.1. But when using squid I am using ports 3128 and 3129.
So I created a second NAT rule - made a copy of the existing DNSBL rules - but with the squid ports.
Further I let pfsense create an "associated firewall rule" to make sure that access is allowed and further I wanted to use it to enable logging on this rule.So after these additional configuration options it is working for me. I can see the 1x1 pixel gif when accessing http or https and I get the access logged in the pfBlockerng Alerts tab.
So in a short summary I would say these additional steps have to be done when you want to use DNSBL togther with squid (and PAC file).
-
Define in the proxy PAC file to NOT use (go DIRECT and no through the proxy) the proxy for the DNSBL VIP. Probably best is to NOT use proxy for any private subnets like 192.168./16, 172.16./12, 10./8
-
Add an additional NAT rule for your proxy ports 3128 and 3129 - or whatever ports you used in your squid config
-
Create an "associated firewall rule" based on the NAT rule(s) you created and make sure it is placed in the correct order in your firewall rules and is not hidden by any other rule.
@BBcan177
Any idea to put an option into your package which allows the user to enable "Squid Proxy Support". Then the user should put in their squid ports and then DNSBL will automatically create an additional NAT rule for these ports and will create an additional Floating/Firewall rule. Then perhaps giving a little hint that when using PAC file the user needs to configure it PAC file to bypass proxy and go direct.
Don't know if you need this when using tranparent proxy.This option should be disabled by default so it will not cause any problems for the majority of users who do not use squid proxy and DNSBL together.
–--- EDIT -----
It looks like the additional NAT rules are NOT needed.
BUT the additional Firewall Rule IS needed.

Hi everyone!
I'm looking for some help to solve a strange issue with pfBlockerNG and OpenVPN.
On pfSense I've both OpenVPN client and server. Everything worked fine until I installed pfBlockerNG. Then, every 2 times I restart pfSense, the service status shows that OpenVPN server is not working.The thing is: OpenVPN server actually works if I test it! I can connect as normal, it's just pfSense that thinks it's not working.
If I reboot pfSense, then everything turns back to normal, and the problem reappears if I reboot once again, and so on.On boot, OpenVPN log reports this error:
May 5 17:43:13 openvpn 30398 TCP/UDP: Socket bind failed on local address [AF_INET]192.168.1.100:1194: Address already in use
192.168.1.100 is the WAN address. If I try to restart the service, i get a TUN/TAP device busy error, since it's actually being used.
It doesn't help to disable pfBlockingNG, but if I uninstall it then the problem disappears.
Another thing that "solves" the problem is to remove all the firewall's rules on OpenVPN, but then I have to manually add them again after reboot and remove them before the next reboot.What am I doing wrong? What did I miss?

The only way I can see pfBlockerNG interfering with OpenVPN, is if you configured the DNSBL Port to use 1194?
Can you describe your Interfaces? and are you using DNSBL?

I tried DNSBL, but now it's disabled. I haven't changed the DNSBL's port, btw.
This is the list of my interfaces:
WAN - eth0
LAN - eth1
WIFI - wlan0
CLIENTS - vlan1
SERVERS - vlan2
BRIDGE - between WIFI and CLIENTS
VPN - used by VPN client -

I thought of it too, but I can't find any difference on the firewall rules from when I don't have pfBlockerNG installed and when I do.
Plus the fact that it happens once every two reboots leaves me very confused… -

I've got pfSense at home and I wanted to put the lvl1 bluetack list in pfBlockerNG but when I get to that entry, it takes a long time for it to load and can make new DNS queries time out (I'm guessing since it's making changes to Unbound?)
Everything else is working fine. Running on a AMD Athlon II X2 240 Processor with 3GB of RAM.
Do I just need to throw more RAM in there or is there something I can tweak to fix this behavior?
Thanks,
-Nick-

I guess that Level 1 Bluetack is a subscription list… Not sure how many IPs are in that list? But I assume that its an IP list and not a DNSBL list, so it should be added to the IPv4 Tab. It shouldn't timeout Unbound tho...

Hi all,
I’ve just tried to install pfBlockerNG on pfSense 2.3.1_1 and I got error message:pkg: https://pkg.pfsense.org/pfSense_v2_3_1_amd64-pfSense_v2_3_1/All/pfSense-pkg-pfBlockerNG-2.0.17.txz: Not Found Failed

Hope someone can help I have outbound deny selected on the IPV4 list below
Alias Name Alias Description Action Frequency Logging
IBlock pfBlockerNG IBlock Deny_Outbound 04hours enabledPRI1 pfBlockerNG PRI1 Deny_Outbound 01hour enabled
PRI2 pfBlockerNG PRI2 Deny_Outbound 04hours enabled
PRI3 pfBlockerNG PRI3 Deny_Outbound 04hours enabled
SEC1 pfBlockerNG SEC1 Deny_Outbound 04hours enabled
TOR pfBlockerNG TOR Deny_Outbound 04hours enabled
MAIL pfBlockerNG MAIL Deny_Outbound 08hours enabled
Now I want to keep all the listed enabled but i keep getting some good sites blocked like dropbox.com.
Can someone advice how i can exclude these destination domains please. I have tried the advance rule outbound invert but when i do it locks me out of the firewall interface.

If an IP is getting blocked, then you can either: 1) Suppress the IP from the Alerts Tab 2) Create a new pfBlockerNG alias (Whitelist), and add the IP to the customlist and set the format to "Permit Outbound". Ensure that the "Rule Order" places the Permit Rules, above the Block/Reject Rules.
If a domain is getting blocked by DNSBL, then you need to suppress it from the Alerts Tab.

any suggestions what its might be ?The bogons is handled by the pfSense code not pfBlockerNG. Maybe try to disable and re-enable Bogons to see what that does. The package changes the max table entry in the advanced settings automatically so it shouldn't be that.

will do it and report back,
can i filter the internet with this package ?
block adult websites ? porn ?
does the package wordt with squad guard and squid 3 ? -

BBCan- first off, great work. Been using pfblocker for a bit and love it (one of my favorite packages on pfsense.) Second- trying to suppress an internal IP (ie. 192.168.1.xxx). I do not have ANY + sign in the alerts tab to add it to the suppression list. As far as I understand, you can add NATted local IPs to the list right? Even when I modify the alias directly and reload, pfblocker continues to block the packets.
For reference, I am blocking LAN outbound to certain countries and some on WAN too perhaps (not at the box to check.) But regardless, it just seems like my box is not working as it should. I'm running 2.3.1-p5 but I DID upgrade from 2.2.6 with pfblocker still installed (I stupidly didn't uninstall before the big upgrade.)
Any ideas?

You don't suppress Internal IPs.. Suppression is for External IPs and the Suppression Icon is only visible when "suppression" is enabled, and when the External IP is a /32 or /24. Also it won't suppress for Country Blocking…
To have some internal IPs excluded from the Block Rules… Best to use the "Adv. Inbound/Outbound" Rule settings.

Sounds good. Part of me thought that I'd have to adjust the rules and couldn't use the suppression but I figured I'd try.
Thanks again mate. -
pfsense 2.2.6
I use the country lists to pretty much block anything outside of US/CA
I then have a whitelist set up for any exceptions
I am pretty sure that in the past this worked fine.
At some point the whitelist stopped having any effect.
The firewall rules order also seems incorrect in that the whitelist follows the pfb block lists
After poking around in the settings I found that setting the Rule Order to :
pfB_Pass/Match|pfB_Block/Reject|pfSense_Pass/Match
seems to get things working correctly - and the rules are now ordered as expected with the pass rule above the block rules.
Did something change that requires using this rule order rather than the default to get whitelists to work ?
I would have thought that this and the default would have been the same thing as far as whitelisting goes.
Although this works I am concerned that this may have unforeseen consequences. -

The DNSBL parser is expecting the CSV line to be in a specific format. As you can see from your text editor, the CSV format is different between the two lists...
I would rather not add another function to the DNSBL parser as its just more overhead to go thru for all the other CSV formatted lists. The feeds that I listed above will work just fine as is...
I also recommend to use the .GZ feed, as that will save both BBC and yourself some bandwidth...
-
Ok thanks, will adjust the feed to gz.

Ok but thanks for working on this, very nice.
Another thing, I forgot.
In another feed is 127.0.0.1 listed and does not seem to work well with Squid.
Removing the line manually solves it, I should contact them?

In the case of Firehol, that site updates those feeds once per day. I ususally update the Feeds more often depending on the frequency of updates for a particular Feed. A lot of Feeds make changes hourly... So getting a feed updated once per day, doesn't really do you justice, and I recommend to add the Original Feed source directly into pfBlockerNG and not go thru a third-party to get a Feed.
Also note, that you can enable "Suppression" in the General Tab, which will remove all RFC1918 and loopback addresses automatically which will avoid this issue for the future…

Was thinking about that too now. Next time I have time enough will try to find the original ones.

Yeah I saw that but it`s not removing 127.0.0.0/8, 10.0.0.0/8 and 192.168.0.0/16.
0.0.0.0/8 is also on there (:Will remove that list later, tomorrow another day.
