First of all i never tried what i'm gonna suggest, but you dould document and try it out if you like it :)

When i was documenting about Linux Virtual Server i found very interesting information about redundancy of Firewall with Director funcionts managed with an "Active-Active" solution.

you can take a look at http://www.linuxvirtualserver.org
and http://www.ultramonkey.org/papers/active_active/active_active.shtml
In this configuration the 2 firewalls share the same IP and MAC Address. Then , using a daemon called "saru", they divide the load in two parts and handle them in a load balanced - fault tolerant way.

It seemed very interesting and i think i'm gonna try it as early as i can.

check it out :)

Bye
