Using clusters to manage gateways

Configure two clusters into one virtual box, and share one IP address. You'll need to use dynamic routing on the client. Many networking products have failover capabilities built into them. Using software is the more effective way to solve the problem, because you don't have to worry about reconfiguring clients correctly to deal with the redundancy. Point them all at your one gateway IP, and let the router software do the work.
