Hello Sunish,

NAT is not supported on C3560.

Only C6500 with Sup720 supports hardware assisted NAT

you likely need to deploy a sw router to perform NAT

Hope to help

The 3560 does NOT support NAT,

However there are/can exist NAT commands in the IOS for the 3560 switches but the commands do not work.

When you type the command it does not say it does not work it accepts it just as it should work, but it just does not do anything.

good luck
