PfBlockerNG v2.0 w/DNSBL

BBcan177

When creating the Alias are you add them into a larger group or are you leaving them as they are individual items? Is there a limitation on amount of alias you can add to a group?

That is personal preference… There is no limit to either method...

I prefer to create an "ADs" alias, "Malicious" Alias etc instead of making an Alias with a single feed in it.... The other post that you linked has the "DNS Group Name" listed also for your reference...

Getting error when rebooting with latest PFblockerng not certain what the error is. Any help on how to fix would be appreciated.

Thanks

That error is normal. It's because when you reboot pfsense, pfblock needs some time to make the alias and the firewall complains about it.

The error "PF was wedged/busy and has been reset" is an issue… When using "Alias type" rules, you can sometimes get an error when re-installing the package, or rebooting if you have a nanobsd or ramdisk installation; however, this error is indicating an error in loading the rules. Not enough information to help you diagnose it... If it persists, maybe try to uncheck "Keep Settings", and disable pfBlockerNG, then "Save". Following that re-check "Keep Settings", and re-enable, followed by a "Force Reload"... There can also be an issue with a non-pfBNG rule that is causing this issue.

Why is it that my whitelist keeps getting pushed to the bottom of my floating firewall rules when it is at the top in the IPv4 lists? It was added after the blocklists, but as stated, its been moved to the top in the IPv4 tab in pfBlockerNG? I have to manually move it to the top of the floating firewall rules every reload.

Select the "Rule Order" setting that is appropriate for your setup in the General Tab.

Thank You.

Few things I found out while beta testing V2

Unbound has an issue in my setup using OpenVPN connected to PIA. It does not start correctly when a network issue is sensed, em1 or openvpn interfaces flap for example. The core problem seems to be how the rc scripts handle unbound reload. They do a HUP vs reload to get around the cache being lost. Disabling "DHCP Registration" or "Static DHCP" was a workaround that allowed unbound to start correctly.

Checking "DHCP Registration" or "Static DHCP" causes other issues with unbound, this is a know issue being talked about in the DNS forum. I added all my hosts host to unbound statically as a work around

Tony, there are some recent posts from people either trying to get OpenVPN/PIA and pfBlockerNG/DNSBL working together or like me, looking to head that direction after I get some other fine tuning in place. Can you please elaborate or cookbook your setup if it is indeed working correctly.

For the 5 folks who asked me privately to keep you informed if I get any info on this… I'll be asking these questions publicly. If someone does respond privately I'll forward responses only if the OP approves. Really, no one here bites (well, maybe Dok - grin)

I am trying to setup the DNSBL portion of pfblocker and ran into a strange problem. I have a pretty restrictive firewall setup where it's pretty much default deny; allow by exception. When setting up the DNSBL portion, I see that the workstations are just timing out when accessing a known blocked site in the DNSBL. In the firewall logs for pfsense, I see the workstation trying to get to 127.0.0.1:8081. I fixed this timeout by adding the 127.0.0.1:8081 in the firewall and now it works properly.

Why does DNSBL try doing a localhost instead of the 10.10.10.1?

Thanks!

DNSBL create a NAT port forward to 127.0.0.1

Makes sense. Thank You!

Do you need to create different Port Forward for different zone i.e LAN, WIFI, Guest?

I see alot of DNSBL alert, but no permit or match? is this working correctly?

No you do not need to create any additional NAT rules.. However, in the general tab, you can click the checkbox to create a 'Floating permit rule' for other LAN subnets (WIFI, Guest etc…) to access the DNSBL VIP address. Also ensure that you do not have any other restrictive rules (as wiz561 posted above).

Not sure what you mean by "Permit and Match" as that only refers to IP rules, and not DNSBL?

@BBcan17,

The wrench/spanner/settings icon for the pfBlocker widget doesn't work with pfSense 2.3/ pfBlockerNG 2.0.6,

Appears you just need to an ID statement to the DIV tag to the pfblockerng.widget.php (line 500 approx.):


Not really worth me putting a pull request just for this, but maybe something for your next pull request?

Thanks Exolon, I guess one of the latest pfSense commits broke that ;) I have tested the change at line 500 and it seems to correct the issue…

Thanks!

When DNSBL is running, I have looked at the Alerts to find site is working, but not able to see the images. How do I find what is blocking the site images

Click F12 in the browser and goto "console" it will show the domains that are blocked… Its also visible in the Alerts tab. You can also suppress a domain by clicking the "+" icon in the Alerts Tab.

I'm running DNSBL_DNSBLEasyList and have selected all the categories. I notice that I don't get any hit on these categories. is there a way to test if this is working correctly?

Since DNSBL uses deduplication and as Easylists are the last to download, the most popular ADvert servers are being blocked by other Feeds… You can view the Easylist Domain list in the pfBNG Log tab and try to browse to any of those as a test.
