Default Website Blocked Message not showing

And what version of pfsense are you on and what version of pfblocker are you using..

Give an example site that you feel should give you that block page. You sure your browser is not using proxy or doh for its dns.. Both of which would stop pfblocker from working, or your machine using a different dns even.

Are you saying the site is blocked you just don't get the block page?

Pfsense Version Used is- 2.4.4-RELEASE-p2 (arm64)
pfBlockerNG-devel Version- 2.2.5_22
Porn Sites that I have blocked manually by adding to list or that matter any blocked site gets "The connection was reset" message.

But they resolve to 10.10.10.1

Same issue here, trying to setup pfBlockerNG:

Same versions :
-pfSense 2.4.4-RELEASE-p2
-pfBlockerNG-devel Version- 2.2.5_22 (did try the stable version beforehand, which had the same behaviour)

Listed websites in DNSBL Feed (PiHole lists) do get trapped, and redirected to the blocking VIP (10.10.10.1).

Chrome browser displays ERR_EMPTY_RESPONSE

The VIP can be pinged properly

Curl shows that the website published by this address is indeed empty althought there is a reply :

~ > curl -v http://adk2.com/

Trying 10.10.10.1...
TCP_NODELAY set

The web server publishing the blocking page seems to have a problem pushing a content.

The lighttpd package in the pfSense repo has recently been updated from version 1.4.49 to 1.4.51. Version 1.4.50 contains the following change:

[mod_rewrite] require rewrite result to begin ‘/’

This is why the blocked page is no longer showing for some ppl. To (temporary) fix it you can open edit " /var/unbound/pfb_dnsbl_lighty.conf" there find all occurrences of:

url.rewrite-once = ( ".*" => "index.php" )

and change them to:

url.rewrite-once = ( ".*" => "/index.php" )

after that restart the pfBlockerNG DNSBL service.

You'll probably have to redo the fix after changing DNSBL related settings or updates of the pfBlockerNG-devel package until @BBcan177 has properly fixed the package.

Thanks.... It worked. Thank you Grimson.

Lefuneste

Wow thanks Grimson !! You deserve a beer !

johnpoz

Agreed for sure that @BBcan177 should by him a beer or even 2 ;)

@Grimson said in Default Website Blocked Message not showing:

edit " /var/unbound/pfb_dnsbl_lighty.conf"

The pfb_dnsbl_lighty.conf file is created during installation or when the file is missing.

To make a more permanent change you have to edit /usr/local/pkg/pfblockerng/pfblockerng.inc and change 2 occurrences of url.rewrite-once = ( ".*" => "index.php" ) in function pfb_create_lighttpd() around line 1065

// Function to create DNSBL Lighttpd configuration file
function pfb_create_lighttpd() {
	global $pfb;

	$pfb_conf = '';
	$pfb_conf = <<<EOF
#
#pfBlockerNG DNSBL Lighttpd configuration file

...


}
	$pfb_conf .= <<<EOF

\$HTTP["scheme"] == "http" {
	url.rewrite-once = ( ".*" => "/index.php" )
}

\$HTTP["remoteip"] =~ ".*" {

...

	$pfb_conf .= <<<EOF

	\$HTTP["host"] =~ ".*" {
		url.rewrite-once = ( ".*" => "/index.php" )
	}
}

EOF;
	return $pfb_conf;

@RonpfS I asked BBcan177 on reddit if he recommends this instead, as the next fix I believe will not be out for a while. Maybe BBcan177 could chime in on this thread?

Regardless, thanks for fix!

EDIT: per BBcan177: I have a PR to fix this and its waiting on the pfSense devs to approve and merge. So either way will work until the next version is available.
