This requires:

      * Detecting the failure of the primary firewall. This is done
        using the exchange of "I'm alive" messages and there are
        daemon's for that.
      * Upon failure, reconfigure the internal NIC's IP address (and
        optionally its MAC address) to match the primary's.

It doesn't really involve Shorewall.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
