Sometimes, even with all the hard work done to prepare your setup, issues occur. Generally it’s always good to check your logs (System ‣ Log Files or the ones found in the module your trying to setup), but sometimes more help is needed.

General issue workflow

Before reporting issues, please make sure yours still exists on the latest version. We generally advice to check the existing issues and our forum before reporting new ones.

In case your issue was introduced after a (minor) upgrade, you can use opnsense-revert to downgrade specific packages installed on the system.

Using the firmware section (System ‣ Firmware ‣ Status) you can perform a health check on the system, on the bottom of the status overview is a button named Run an audit which can be expanded to offer the Health selection.

When clicked this outputs something like the following:

>>> Check installed kernel version
Version 19.7.3 is correct.
>>> Check for missing or altered kernel files
No problems detected.
>>> Check installed base version
Version 19.7.3 is correct.
>>> Check for missing or altered base files
No problems detected.
>>> Check for and install missing package dependencies
Checking all packages: .......... done
>>> Check for missing or altered package files
Checking all packages: ....
opnsense-19.7.4_1: checksum mismatch for /usr/local/etc/inc/
Checking all packages...
Checking all packages......... done

When mismatches are reported, you can reinstall affected packages in the Packages section of the firmware screen. In the case above you would reinstall opnsense, since the looks tainted.


We advise to include the output of the health check if it seems to report issues when creating bug reports on GitHub.


Always try to be precise in issue reports, either if their about a possible bug or a feature request, it helps if intentions are absolutely clear. Our GitHub repositories use templates which should guide you through, we kindly ask you to use them (tickets not using our templates are treated as low priority).
