Hi Tarunava,
Are you connecting to 2 ISPs? Public IP address that you nat on the firewall belonging to ISP1 or ISP2? If so you can nat only on one ISP.
Seems you need to seperate the traffics by using the services/ports.Let's assume that you want to Nat both links with each pool ip address.
ip access-l ex Proxy-80
permit tcp host any eq 80
ip access-l ex All-Traffics
permit ip host any
route-map input permit 10
match ip address Proxy-80
set interface RouterInterfaceToISP1 RouterInterfaceToISP2
route-map input permit 20
match ip address All-Traffics
set interface RouterInterfaceToISP2 RouterInterfaceToISP1
Interface
ip policy route-map input
----------------------
route-map interfaceISP1 permit 10
match interface RouterInterfaceToISP1
route-map interfaceISP2 permit 10
match interface RouterInterfaceToISP2
ip nat inside source route-map interfaceISP1 pool Pool-ISP1
ip nat inside source route-map interfaceISP2 pool Pool-ISP2
int Interface
ip nat inside
int Interface
ip nat outside
int Interface
ip nat outside
Hopes that makes you some idea.
Thot
