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. 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.
