* Return output of iptables directly instead of writing it to files. * Make iptables wait for 5s if xtables is locked by another iptables process. (--wait 5 argument) * Add optional parameter "-x" to have iptables report exact numbers. * Add optional parameter "-f" to display the filter table (default). * Add optional parameter "-n" to display the nat table. * Add optional parameter "-m" to display the mangle table. * Adapt iptables.cgi and guardian.cgi to catch getipstat output instead of reading temp-files.
