The NATing is possible, but what will you do about the default routes? The PIX supports default routes pointing out to only ONE of its interface at the same time, not more than one.


Or this is an active/backup scenario?

you can nat private ip address of server with 2 ISP's public ip address.... but only one will work at a time. When ISP1 goes down the server is access via ISP2 public ip address and vise-versa.


It will only work in Active\standby scenario.. same goes with your internet traffic.

Other firewalls in the market support this, Cisco PIX does not.
