My Local IP : 10.2.X.X

My Remote IP :10.3.X.X

Can any one support me for the error

Hi,

Your after-auto dynamic PAT takes the precedence over static NAT...

nat (inside,outside) after-auto source dynamic any interface

You have to reconfigure you NAT or PAT rule defined in your firewall.

no nat (inside,outside) after-auto source dynamic any interface

object network local-lan-pat1

subnet 10.2.0.0 255.255.255.0

nat (inside,outside) dynamic interface

!

object network local-lan-pat2

subnet 10.60.1.0 255.255.255.0

nat (inside,outside) dynamic interface

!

no nat (inside,outside) source static DM_INLINE_NETWORK_1 DM_INLINE_NETWORK_1 destination static NETWORK_OBJ_10.3.0.0 NETWORK_OBJ_10.3.0.0 no-proxy-arp route-lookup
!

access-list outside_cryptomap extended permit ip 10.2.0.0 255.255.255.0 host 10.3.0.0 255.255.255.0

no access-list outside_cryptomap extended permit ip object-group DM_INLINE_NETWORK_1 host 10.3.0.0

!

Hope you are making this between subnets..... not to the single host in the other end.
