The objective of this project is to develop and maintain a script that installs NxFilter DNS based web filter software on FreeBSD-based systems, particularly the pfSense firewall. Derived from the unifi-pfsense repository. NxFilter works well and offers flexible filtering options, however you should have some basic network knowledge to properly install and configure all options.A script that installs NxFilter software on pfSense. The easiest way to block content by category is to download a blocklist from (see documentation), which allows you to quickly add dozens of pre-configured categories with almost 2 million websites.
NxFilter can also be integrated with AD/LDAP. You can also create content categories that allow you to group multiple domains into a category that can be blocked or quota limited. NxFilter supports multiple content policies can automatically apply a certain policy to a specific user. You can configure the filtering options from a browser based interface (Default password: admin) that also provides statistical charts and detailed reports. In order to route your Internet traffic through NxFilter, you will need to change the DNS settings on all machines that you want to protect to use the IP address of the NxFilter instance (instead of your regular DNS servers).Įach machine that uses the NxFilter server in their DNS will be automatically protected based on your global or user based settings. NxFilter is installed on a single PC, where it acts as a DNS proxy server. In addition, it can use DNS packet inspection to protect your network from malware and botnet activity. NxFilter is a DNS filtering server that is capable of filtering Internet traffic based on domain names and content categories.
