How to do destination NAT in a 2600 router with IOS 12.3?

Question

Hi All
I have a 2600 router with two LAN interfaces which I am using for a PoC and has the following settings:
FE 0/0 - 10.0.0.1/24 - client LAN - inside 
FE 0/1 - 10.1.1.1/24 - server LAN - outside 
The direction of the flows are from the clients to the servers. What I would like to achieve is when clients accessing the web server 10.1.1.10, this to be replaced by 10.1.1.100.
I have tried the above a few times but doesn't work. Is the above possible? And If so please provide me with a sample config.
Many Thanks

Yes, you can do this.  You don't need destination NAT.  Source NAT translations work both ways.  This should work:
ip nat inside source static tcp 10.1.1.100 80 10.1.1.10 80
int fa 0/0
ip nat inside
int fa 0/1
ip nat outside
The bigger question is why you'd want to.  Just because you CAN do something doesn't mean you SHOULD.  Unless you have the 10.1.1.0 network subnetted or some sort of firewall/blocking in place, both IPs should be reachable by the hosts.  Why not just have them go directly to 10.1.1.100 instead of going to 10.1.1.10?  If there's a firewall or similar blocking 10.1.1.100, why not adjust your firewall settings instead?  You could have a valid reason for doing this but I can't think of very many scenarios off the top of my head where this would make sense.  If you can post more details on what you're trying to accomplish, you might get better advice on a better way to solve the problem.
