Open in new window

will show you, is not NATTED i.e not tranlated to the public IP address, this is usually (but not always) used to stop VPN Traffic being NATTED when going to a remote site.

So ASA Pre 8.3 (which is in use in your example above)

nat (inside) 0 access-list EXEMPT
access-list EXEMPT extended permit ip

Open in new window

Would not tranlate any traffic going from10.254.254.0 to

This code has changed on the newer ASA's to do the same you would need,
object network obj-
object network obj-
nat (inside,any) source static obj- obj- destination static obj- obj-
