As a contributor to the SANS ISC, I email my IPTABLES logs hourly to the Dshield database, however the default IPFire IPTABLES logs are incomplete since packets dropped by Locationblock are not logged to syslog.
As a workaround I edit the locationblock function of rules.pl to add a IPTABLES rule to log the dropped packets. This edit does not of course survive any Core-Updates that upgrade rules.pl and the edit needs to be re-applied.
In addition, unless the Locationblock packets are logged to syslog the data displayed in the Firewall logs sections are incomplete as the packets dropped by Location Block are not displayed.
I understand that the original intension of the Location Block feature was to reduce the amount of log messages on installations running on extremely cheap flash storage. I suspect that these installations are now almost zero especially since IPFire no longer supports 32 bit versions.
The obvious solution to this to make Location Block logging selectable as a firewall option and my quick look at making a patches for this would seem to be fairly simple task to rules.pl and and optionsfw.cgi.
I would be happy to provide the necessary patches should this be acceptable.
