Here's a rough and ready version; as always, check that the location of your perl program is correct after the "#!" :
Code:
#!/usr/bin/perl -w

while ( <> ) {
    if ( m/blocking/i | m/deny/i ) {
        print;
    }
}

How do you execute it I hear you cry? Save it as a file called firewall_extract.pl, make it executable, and it should be as follows:

./firewall_extract.pl <path_to_firewall_log >file_for_output

NAME
perlivp - Perl Installation Verification Procedure SYNOPSIS
perlivp [-p] [-v] [-h] DESCRIPTION
The perlivp program is set up at Perl source code build time to test the Perl version it was built under. It can be used after running: make install (or your platform's equivalent procedure) to verify that perl and its libraries have been installed correctly. A correct installation is verified by output that looks like: ok 1 ok 2 etc. OPTIONS
-h help Prints out a brief help message. -p print preface Gives a description of each test prior to performing it. -v verbose Gives more detailed information about each test, after it has been performed. Note that any failed tests ought to print out some extra information whether or not -v is thrown. DIAGNOSTICS
o print "# Perl binary '$perlpath' does not appear executable. "; Likely to occur for a perl binary that was not properly installed. Correct by conducting a proper installation. o print "# Perl version '$]' installed, expected $ivp_VERSION. "; Likely to occur for a perl that was not properly installed. Correct by conducting a proper installation. o print "# Perl @INC directory '$_' does not appear to exist. "; Likely to occur for a perl library tree that was not properly installed. Correct by conducting a proper installation. o print "# Needed module '$_' does not appear to be properly installed. "; One of the two modules that is used by perlivp was not present in the installation. This is a serious error since it adversely affects perlivp's ability to function. You may be able to correct this by performing a proper perl installation. o print "# Required module '$_' does not appear to be properly installed. "; An attempt to "eval "require $module"" failed, even though the list of extensions indicated that it should succeed. Correct by conducting a proper installation. o print "# Unnecessary module 'bLuRfle' appears to be installed. "; This test not coming out ok could indicate that you have in fact installed a bLuRfle.pm module or that the "eval " require "$module_name.pm"; "" test may give misleading results with your installation of perl. If yours is the latter case then please let the author know. o print "# file",+($#missing == 0) ? '' : 's'," missing from installation: "; One or more files turned up missing according to a run of "ExtUtils::Installed -> validate()" over your installation. Correct by conducting a proper installation. For further information on how to conduct a proper installation consult the INSTALL file that comes with the perl source and the README file for your platform. AUTHOR
