Building 1 Server(

Building 2 User Subnets(10.10.10.x)

User Subnets(10.10.20.x)

As per the above mentioned, i have Building 1 wherein the server is available.

In the Building 2 i have 2 subnet users 10.10.10.x and 10.10.20.x.Could some one give me a solution wherin subnet 10.10.10.x should be accessing the server IP as it is and subnet 10.10.20.x should be accessing the server IP through a Natted IP( instead of tried doing a destination based nat but then its affecting the 10.10.10.x users.Please share your thoughts.

Hi Jkannan

Have a look at this document which uses route-maps to selectively do destination NAT.

Be aware you need at least 12.3(14)T IOS or later to be able to use this feature.
