I have a static NAT configured on my ACE that translates an internal IP to an external IP, but I want the same internal IP to maintain its IP when destined to a certain network. It's the same concept that is used on PIX/ASA with a nonat rule (nat 0). Any ideas on how to accomplish this?
Here's my static NAT config:
class-map match-all cmap-static-10.20.1.10
2 match source-address 10.20.1.10 255.255.255.255
policy-map multi-match pmap-nat-vl4001
nat static 184.108.40.206 netmask 255.255.255.255 vlan 501
interface vlan 4001
service-policy input pmap-nat-vl4001
basically you need to change the match source-address into a match ACL and create an ACL that deny the destination ip for which you want no nating and permit the rest.
