Hi I installed Fedora core 2 and configured iptables with Guarddog and all works correctly (I know to configure iptables manually is better but I need to study it before manually write a configuration file). My problem is that I need to know if is possible or not always logging source mac address. With guarddog I tried all log levels ("debug", "alert", "critical") but the problem is that mac address is not always registered. Is there a way to log in all conditions (not only with drop or reject) the source mac address??? Thanks a lot Marco Italy --- Outgoing mail is certified Virus Free.
