Firewall, version #3 ( #2 < #4 > ... #13)

General

I use a perl script that was written by alex. A added some features like multiple dialup interfaces and a blacklist.

The perl script is calles myfw.pl and has a couple of options. The basic ones are the configuration file and the blacklist file. You network address and the IPs of you local machines should be modified at the top of the script.

The configuation file consists of lines of iptables commands that are a bit shortened by omitting the "iptables" command name. Additionally one can use variables in the lines.

The black list is a file that contains in each line an IP and maybe a comment. The IPs can be used in the configuation file with the variable $BLACKLIST.
