Not sure entirely what you mean. If you mean NAT the outbound traffic to another ip then you NAT traffic as normal and then in your crypto map access-list refer to the Natted address eg.

source =

destination =

Natted source =

static (inside,outside) netmask

access-list vpntraffic permit ip host host

crypto map mypmap 10 match address vpntraffic

Hello Raghavendra,

Below are some IPSEC sample configuration with Overlapping subnets that might help you with doing NAT and then configuring IPSEC for NATted Traffic.
