To work around this, we can download the NxFilter software directly from the NxFilter homepage during the installation script process. ‼️ Challengesīecause the NxFilter software is proprietary, it cannot be built from source and cannot be included directly in a package. ‼️If you have already set up your system to use legacy BIOS, MBR partitons, and ZFS, then do not run this script. To avoid this problem, use UEFI mode if available, use GPT partitions, or use a filesystem other than ZFS. It appears that one of the dependency packages may cause this. Again, using this script on a system with an MBR formatted ZFS root volume will break your system. WarningThis script will destroy a legacy BIOS system booting from an MBR formatted ZFS root volume see #168. The script is known to work on FreeBSD-based systems, including pfSense, OPNsense, FreeNAS, and more. 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 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. Then you can filter the whitelist with nxFilter.A script that installs NxFilter software on pfSense. Then I made the primary DNS Server on pfSense to be 10.127.1.240(which is my nxFilter) and the secondary DNS Server 1.1.1.1 and on NxFilter I have made my upstream DNS Server 10.127.1.254 which points back to pfSense. IPv4 TCP/UDP * * * 53 (DNS) * Block All other DNS Servers
Protocol Source Port Destination Port Gateway Description If i change the DNS address on device level to the IP of any other DNS Server it auto-bypass the NxFilter which I understand it will do, thus have I implemented firewall rules to block access to any other dns server, firewall rules as follow. So I run pfSense (10.127.1.254) as the main firewall/router and on a separate device I have NxFilter (10.127.1.240) to filter the DNS content which works great. I want to filter web content at the DNS level.
