Special case of NAT! Is it posible with Cisco router?

I have two web servers on diferent places in internet. The primary server is connected through ciscorouter directly to internet. The second one is backup server longdistanced somewhere on internet. In case the primary server goes down I need to establish transparent NAT redirection to the second one. It means when any packet come to cisco(looking for the primary server), the cisco translate both packet ip addresses and send it to second server through the same interface, which received incoming packet.Source address has to change to IP address of cisco and destination address to IP of backup server.

When replies come back it translate back.

How could I do it with one interface?

I would probably set up a tunnel between the primary and remote sites, then run NAT over the tunnel.

I don't have enough information on your topology, but with a little tweaking, this should work.
