I have an internal webserver with a private ip-address. I want to let one spesific, external address access this web-server and therefore need to configure port-forwarding on my ASA 5520 running version 8.3(2). How should I configure this?

Thanks for the tip, but this is for an old version. NAT/PAT was completely rewritten in version 8.3 so I need updated info on this.

Here's a specific example:

8.2 style commands:
access-list outside-in extended permit tcp any interface outside eq smtp
static (inside,outside) tcp interface smtp smtp netmask

Same in 8.3 :
object network obj-
access-list outside-in extended permit tcp any object obj- eq smtp
object network obj-
 nat (inside,outside) static interface service tcp smtp smtp
