help...pix failover in lab scenario

[mjsully]

I have a PIX firewall in a lab that plugs into a dsl modem for its internet access. The outside interface of the pix has a static public address. I want to replace the pix with a pair of pix's running failover. However, I don't have a second public address to configure as the failover ip address. How can I get around it so I can enable failover on the outside interface?

just a quick comment.

for testing purposes, you may simply connect the pix outside interfaces to a switch and play with private ip.
