Subject: Fault Tolerant Firewall
Date: January 23, 1996 00:29
We are asked to warrant a >99,5% uptime for a firewall system in a financial
organization. We're trying to figure out what's the best way to manage such
a problem (a fault-tolerant hardware solution? A multiple firewall
other tricky configurations?).
Has anybody out there already experienced and solved such a problem?
