Immerse yourself in the commanding presence of NxFilter, an ingenious, hard-hitting network filtering tool crafted for your local network's ultimate defense.
#NXFILTER NOT WORKING SOFTWARE#
A script that installs NxFilter software on pfSense.Powerful DNS filter tool that can block web sites based on IP address with user restriction against malicious web sites. Derived from the unifi-pfsense repository. 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.
#NXFILTER NOT WORKING INSTALL#
The project provides an rc script to start and stop the NxFilter service and an installation script to automatically download and install everything, including the startup script. The script is known to work on FreeBSD-based systems, including pfSense, OPNsense, FreeNAS, and more. WarningThis script will destroy a legacy BIOS system booting from an MBR formatted ZFS root volume see #168. Again, using this script on a system with an MBR formatted ZFS root volume will break your system. It appears that one of the dependency packages may cause this. To avoid this problem, use UEFI mode if available, use GPT partitions, or use a filesystem other than ZFS. ‼️If you have already set up your system to use legacy BIOS, MBR partitons, and ZFS, then do not run this script.
‼️ Challengesīecause the NxFilter software is proprietary, it cannot be built from source and cannot be included directly in a package. To work around this, we can download the NxFilter software directly from the NxFilter homepage during the installation script process.
The pfSense updater will remove everything you install that didn't come through pfSense, including the packages installed by this script.īefore updating pfSense, save a backup of your NxFilter configuration to another system.Īfter updating pfSense, you will need to run this script again to restore the dependencies and the software. You can then restore your previous configuration from the saved backup file, stop NxFilter and copy the config.h2.db into /usr/local/nxfilter/db directory. Log into the pfSense webConfigurator(System- > Advanced -> Admin Access) and change the TCP port to something other than port 80 and disable the WebGUI redirect rule.To install NxFilter and the rc startup script: UpgradingĪt the very least, backup your configuration before proceeding.īe sure to track NxFilter's release notes for information on the changes and what to expect. In the webConfigurator, disable the DNS resolver(Services -> DNS Resolver -> General Settings).NxFilter GUI and block page will need to use port 80. Run these commands, which downloads the install script from this Github repository and then executes it with sh.Log in to the pfSense command line shell as root.In the webConfigurator, create firewall rules(Firewall -> Rules -> LAN) to allow access to the LAN address for NxFilter udp poand tcp ports 80, 443, 19002:19004.NxFilter provides filtering DNS services on port 53. The first step with any issue should be to stop and start the NxFilter service. Grep -i error /usr/local/nxfilter/log/nxfilter.log You should then check the nxfilter.log file in the /usr/local/nxfilter/log/ directory for errors. Issues with the script might include problems downloading packages, installing packages, interactions with pfSense such as dependency packages being deleted after updates, or incorrect dependencies being downloaded.
#NXFILTER NOT WORKING FREE#
Feel free to open an issue for anything like this. Issues with the NxFilter software might include not starting up, not listening on port 53, exiting with a port conflict, stopping after startup, memory issues, file permissions, dependency conflicts, etc.
You should troubleshoot these issues as you would on any other installation of NxFilter. The answers to most questions about setting up or troubleshooting NxFilter are found most quickly on the NxFilter forums. It may turn out that some issue with the NxFilter software is caused by something this script is doing. In a case like that, if you can connect the behavior of the NxFilter software with the actions taken by the script, please open an issue, or, better yet, fork and fix and submit a pull request. This script may create a conflict that breaks Java on a FreeBSD upgrade.DNS filtering is an important part of a well planned firewall. Not only does DNS filtering help protect users from accessing dangerous or unwanted domains, but it can significantly reduce the amount of unwanted traffic on your network. Pi-hole is a free resource that is intended to block ads. OpenDNS is intended to be more of a firewall and is free for home use, but has commercial support available.
