    longDescription = ''
      Shorewall is a high-level tool for configuring Netfilter. You describe your
      firewall/gateway requirements using entries in a set of configuration
      files. Shorewall reads those configuration files and with the help of the
      iptables, iptables-restore, ip and tc utilities, Shorewall configures
      Netfilter and the Linux networking subsystem to match your requirements.
      Shorewall can be used on a dedicated firewall system, a multi-function
      gateway/router/server or on a standalone GNU/Linux system. Shorewall does
      not use Netfilter's ipchains compatibility mode and can thus take
      advantage of Netfilter's connection state tracking capabilities.
