How
about a cold standy? Get yourself another Ultra or a Netra,
something
inexpensive and headless. Build it up as an identical to your
primary. Copy
your
config over, test it out some night after hours. Write up a simple
failover
procedure: as simple as switching your wires from one box to the next
(color
coding
your networks does wonders to simplify this), clear your arp cache
on
your
gateway router, and firing up your secondary.

After
a crash of our firewall machine a couple of weeks ago and spending most of the
night building a new one, has prompted me to look into some other method of
disaster recovery.
I’ve
looked into High Availability but since I’m using a quad Ethernet card and
four different network legs, I’m not sure that this would work. If anyone has any suggestions on the
method they use to protect their main firewall machine, I would greatly
appreciate an email pointing me in the right
direction.
Thanks
in advance,
Richard
