![]() PfBlockerNG uses the DNS Resolver service of pfSense to handle DNS resolutions so before we start the installation make sure your DNS Resolver is running whit the Forwarding mode enabled, this is found under Services -> DNS Resolver -> General Option The only issue whit pfBlockerNG and DNSBL is that it can use a lot of resources both RAM and CPU the more lists you assign it the more RAM and CPU it would need to process all of them, the lowest set of hardware I would recommend using for this is 2Gb RAM and 4Core 1.5Ghz processor. These aliases are generated upon predefined txt files that contain the IP and Domain information that are updated by known security professionals and provider once a bad IP or Domain is identified. How pfBlockerNG and DNSBL achieve to do all this even if the sites uses HTTPS and SSL encryptions is by using DNS bases aliases that has both the Domain and IP to generate the firewall rules. In this guide I will be covering how to use the DNSBL feature of pfBlockerNG package to block users from accessing unwanted websites like porn, Facebook or YouTube and also keep your users safe from known infected website so that the risk of getting infected whit viruses or malware is reduces, this will also clean up Ad’s seen on websites also so you get a better browsing experience. This was pretty neat to watch, but not anything that I see myself using for now.Īdditionally, the interface chart was cool to see how much bandwidth my network was using, and when.Edd Noman's Guide to pfSense 04 – How-To Block Ad’s and Websites using pfBlockerNG I enabled the plugin, told my settings to persist, changed the default admin password, and configured it for my LAN.Īfter the plugin was running, I logged in and took a look at my Talkers flow. ![]() Once I installed the package, I was able to configure it by going to Diagnostics -> ntopng Settings. Per their package description, “ntopng (replaces ntop) is a network probe that shows network usage in a way similar to what top does for processes.” To test my feeds, I tried to visit an advertising site directly, and the router blocked my DNS request!Īs a bonus, I also setup ntopng for some basic visualization. Once I had my feeds selected, I added them to my new DNS Group. To fix this you will need to remove the block, clear the feeds, clear the caches, and possibly restart your router. If you do this (trust me, I did at first), then you will only block your access to the actual block list feeds in question. NOTE: Do not put a link to the Pi-hole ad block list directly, but rather to each individual entry. I started with a number of lists from the Pi-hole ad block list. Selecting the DNSBL Feeds menu option and clicking “Add” allowed me to create a new DNS Group with any number of block list feeds. With the basic settings in place, it was time to set up my actual block list! I enabled DNSBL, set my Virtual IP to 10.10.10.1, and kept my listening ports and interface default. I enabled the blocker, told the settings to persist, and set the CRON job to run every 3 hours.Īfter I enabled the blocker, I clicked on DNSBL to configure my block list. Once I installed the plugin, I was able to configure it by going to Firewall -> pfBlockerNG. Manage IPv4/v6 List Sources into ‘Deny, Permit or Match’ formats.” To quote their description, “pfBlockerNG is the Next Generation of pfBlocker. To start, I installed the pfBlockerNG package by going to System -> Package Manager -> Available Packages. ![]()
