Frequently Asked Questions

Vuurmuur fails to start up with message: Error: checking for iptables-capabilities failed. Please see error.log.

First, make sure you have proper iptables support in you kernel or modules. This means conntrack and iptables support. If you are sure that you have, there is a setting to try. In vuurmuur_conf, go to ‘Vuurmuur Config -> Modules’. There, set the ‘waittime after loading a module’ to 10. Then retry starting Vuurmuur.

Before upgrading Vuurmuur, do i need to uninstall the old version first?

Before upgrading Vuurmuur to a new version you don’t need to uninstall Vuurmuur first, as long as you keep the installation paths the same. If you use the –defaults option, you are ok.
