ApplyChanges

There are a number of ways to enable configuration changes in Vuurmuur.

  1. restart vuurmuur, by running systemctl restart vuurmuur, /etc/init.d/vuurmuur restart or a similar command that kills (with INT or TERM signals) the vuurmuur processes and starts them again.
  2. send a signal to vuurmuur and vuurmuur_log. This must be the HUP signal.
  3. choose ‘Apply changes’ from the main menu in vuurmuur_conf, or press F11 in the main menu.
  4. for vuurmuur_script the option –apply is available, so it applies the changes the same way vuurmuur_conf does

Troubleshooting

If applying the changes failed take a look a the error.log.

If Vuurmuur somehow created an iptables ruleset that iptables refused to load, there will be two files in /tmp/ to inspect. The first is /tmp/vuurmuur-load-result-XXXXXX (the X’s are random characters) which contains the output of the iptables-restore command.

The second will be called /tmp/vuurmuur-XXXXXX.failed. This is the failed ruleset itself. Vuurmuur loads this file with the following command:

iptables-restore --counters --noflush < /tmp/vuurmuur-XXXXXX

You can try to run it manually for debugging. If inspecting the files doesn’t bring a solution, please consider contacting the developers for support.
