Nat – ASA 5510 8.4 Nat & Portforwarding

So I'm trying to forward an internal service on a internal server to the external interface on the same port on the outside interface of our ASA.

I been searching for a solution for days and found nothing.

Here are the relevant parts of my config:

: Saved
:
ASA Version 8.4(2)
!
object service TCP-WebServer-8080
 service tcp source eq 8080
object network WebServer_Object_10.1.10.7
 host 10.1.10.7
object network obj-10.1.100.0
 subnet 10.1.10.0 255.255.255.0
!
access-list outsidein extended permit ip object-group OUTSIDE object-group INSIDE
access-list insideout extended permit ip object-group INSIDE object-group OUTSIDE
access-list webserveraccess extended permit tcp any object WebServer_Object_10.1.10.7 eq 8080
!
nat (inside,outside) source dynamic obj-10.1.10.0 interface
!
access-group webserveraccess in interface outside
access-group insideout in interface inside
!
object network WebServer_Object_10.1.10.7
 nat (inside,outside) static interface service tcp 8080 8080

Here's the packet tracer output:

Phase: 1
Type: ROUTE-LOOKUP
Subtype: input
Result: ALLOW
Config:
Additional Information:
in   1.2.3.4   255.255.255.255 identity

Phase: 2
Type: ACCESS-LIST
Subtype:

output-interface: NP Identity Ifc
output-status: up
output-line-status: up

Drop-reason: (acl-drop) Flow is denied by configured rule

So it looks like it's being dropped by an ACL, but it looks right to me. Can I have some guidance as to what I am doing wrong?
