On the final screen, click “Finish” to apply the configuration. Most likely you can leave the default settings in place but if the IP address or ports are already in use on your network change them to something else. You will next need to configure the web server for DNS blocking, this is the page that you will be redirected to when you try to access a blocked page. If you want to exempt an interface from blocking, don’t identify it as either inbound or outbound. This can be done by holding down the Ctrl key while clicking on the interfaces you wish to add. Normally your WAN interface will be inbound and LAN will be outbound but if you have multiple interfaces configured you may wish to select more than one for each of these sections. Tell pfBlocker which interfaces are inbound and which are outbound and click “Next”. In this case we have not configured anything so it doesn’t matter but bear that in mind if you try to run it again once everything is set up. Click “Next” to begin the wizard and accept the warning that completion of the wizard will wipe all settings. Following the steps in the wizard will give you a basic configuration, blocking outbound access to a small number of known malicious IPs and adding some basic DNS blocklists.
When you first open pfBlockerNG, you will be taken to a setup wizard which will give you a basic configuration. This is where we will configure the blocking settings. Once the package is installed, you will see an entry for pfBlockerNG in the Firewall menu at the top of the page.

Install the development version (pfBlockerNG-devel) as it is just as stable and has newer features including the ability to choose from pre-selected blocklists. It also supports DNS blocking so can fully replace Pi-hole if you choose to enable this feature.įrom your pfSense admin interface, go to System > Package Manager > Available Packages and search for “pfBlockerNG”. PfSense provides a package called pfBlockerNG which allows for advanced and dynamically updating blocking rules based on blocklists or GeoIP data. This means that rather than blocking lookups to malicious hosts, we will need to block them with firewall rules. DNS is also only queried when making outbound connections so a malicious service attempting to make inbound connections would not be blocked. Many malicious services are short lived and may not be linked to a domain name, allowing them to bypass DNS blocks. However, while this approach works well for advertising as it tends to use known domain names that stick around for a long period of time and are usually accessed via DNS queries, the situation is more complex when blocking malware. I have previously talked about using Pi-hole to sinkhole unwanted DNS queries to block advertising or malicious domain names. It also means that if you do get infected, the malware may not be able to reach its command and control servers, protecting you from any remote commands sent by the attacker.

Reducing the amount of traffic leaves more bandwidth available for the traffic you actually want and blocking malicious sites reduces the risk that you will download something potentially dangerous onto your computer. Blocking unnecessary traffic on your network is a great way to improve performance, security and privacy.
