[TriLUG] BSD/Linux firewall with multiple ISP and failover?

[David A. Cafaro]

I've got a friend Jason who does a lot of fail over firewall work using
OpenBSD and carp/pf.  Check it out here:

They have shown very good performance in a corporate environment.  

As for hardware, you might want to check out these people for the
machines to base your system off of:

You should be able to get a couple of pretty beefy 1U systems to build
up your redundant system with here. Take a look at the A-Class iServers.
