Add-On Releases - DnP Firewall : SEO Friendly Double-Protection Layers against Flood / DoS / Spam Bots

DnP Firewall Gateway Demo

*To test Front-End Layer protection : It's the page shows up when you first enter the site.
*To test 2nd Layer Protection : Pass Front-End Layer protection, then Tap (not hold) F5 continuously nonstop for 10 seconds.

DnP Firewall Gateway was designed to stand against the massive DoS attack targeted DnP Network? few years ago. Upon installed, it has been reducing the severe level of many incidents and preventing my forum from being overload ever since. It also nearly blocks away all the automated bots that come to register for spamming on the forum. The last release was almost 3 years ago and there had never been any update to the MOD. Version 0.3 came with many issues though it was very stable. I decide to give another upgrade and simplify the code a little for another release. Don't hesitate to install DnP Firewall Gateway for your forum and hope you will find it as useful as I do.

*This Firewall is compatible with All PHP Forum systems and Search Engines Friendly*

1 - Use this simple Firewall to protect your ( vBulletin / phpBB / SMF / IPB / etc.. ) forum

1. Deny unwanted Bots
2. Reduce Spamming
3. Block Flooding Attack
4. Partially weaken DoS
5. Prevent automated malicious scripts pass through

2 - Side features

1. Increase your Adsense Impression and Revenue.
2. Act as an Introduction page for your forum.
3. SEO Friendly. (DnP Network has this firewall installed for more than 2 years. Google Search : silveryhat returns 29,000+ results)
4. No query executed / Extremely fast

3 - Installation for vBulletin Forum

a. Upload all files from package to your forum_root
b. Open global.php using Notepad. (Why global.php ? Because global.php is the core file of vBulletin system , it is also the initial startup file that calls important database queries and keeps sensitive information. The Firewall comes before any of the processes run to prevent direct damage to the forum. That is the reason why DnP Firewall does not use any hook or come as an automatic plugin like other MOD)

Find

PHP Code:

// identify where we are
define('VB_AREA', 'Forum'); 


Add BEFORE

PHP Code:

if(file_exists('dnp_fw.php')){require_once('dnp_fw.php');} 


Simply remove this line to deactivate the firewall

c. Save and Reupload global.php to your server. Done!

3b - Upgrade
Simply perform step

a.Upload all files from package to your forum_root

*If you have custom layout, do not overwrite dnp_fw_template.php*

4 - Note

Eventhough the DnP Firewall Gateway could reduce the damage of a flooding attack, it does not guarantee that all of the negative affects of an attack could be avoided. I do not hold any responsibility for such matters. As an administrator you should know that there is not software firewall that could be as effective as a hardware firewall.

You are free and encouraged to modify the Layout of the Gateway page in dnp_fw_template.php but please respect the copyrights notice of the author. Additional templates are also available if you'd want different look. (How to change DnP Firewall Template)

DnP Firewall Gateway also acts as an Introduction page for your forum if you fill it up with rich information content of your site. Adsense or other Ads could be placed here to maximize your revenue since every visitor will need to pass by this Introduction page. It almost 100% guarantees that your CTR or Page Impression will raise quickly.

5 - Compability

This MOD can be used with almost any system that runs PHP. Compatible with all vBulletin forum from 3.0.x to 3.8.x

It should not conflict with any existing MODs on your forum.

DnP Firewall Gateway consumes very little server resource because on the surface, it is just a simpe webpage. It does not execute any query, therefore your database will not be affected under any circumstances by this MOD.

DnP Firewall Gateway could together be used with InV-Firewall Script to act as doubled-firewall system that 2 x the strength against Flood /DoS Attack with bonus of denying malicious query and tracking access.

DnP Firewall Gateway is also compatible with DnP Instant! AJAX/SEO Musicbox & News smart anti-flood protection that brings extra power to the firewall.

._. Are you sure the warning message comes from the firewall ? The firewall integrates itself into global.php not requiring it , while the error means showthread.php is looking for global.php but not found. It looks more like a intermittent server issue.

Have you added your forum domain to the domain list in dnp_fw_config.php ? ( Setup Domain List for DnP Firewall Gateway )

[|Jordan|]

Yes i added them.

The link works fine in IE, but in firefox it doesnt for some weird reason. It's been working fine previous days but suddenly stopped working.

Edit: NM i found the problem, my firefox had referrer header disabled. Enabling it again fixed it.

I installed this 2 days ago and it appears to be working correctly, however 2 spambots still managed to register and spam our forum overnight??

I had to turn the flood protection off due to numerous complaints by members, but the firewall has been still functional up until this point... so not sure why it hasn't worked in these instances...

There is a different between spam bots and spammers. Those who can spam with the firewall on are not bots. They are human and they do that on purpose.

You are able to change the flood protection settings following this guide Detail information about DnP Firewall 2nd Layer Protection
