Cisco ASA 8.3 Configuration

Hi,

I am using ASA 5505 8.3

Setup is as follows:

2 Vlans. inside and Outside.

Outside
1.1.1.38 255.255.255.248
route outside 0.0.0.0 0.0.0.0 1.1.1.37 1

Inside:
10.1.1.1 255.255.255.0

object network obj_any
 nat (inside,outside) dynamic interface

object network obj_any
 subnet 0.0.0.0 0.0.0.0

object network PC
 host 10.1.1.39

object network PC
 nat (inside,outside) static 1.1.1.39

10.1.1.39 can access the internet using => 1.1.1.39 fine.
All others can access the internet using 1.1.1.38 fine.

So when I add a ACL example:
access-list outside_in extended permit tcp any 10.1.1.39 eq smtp
access-group outside_in in interface outside

Outside smtp traffic is getting in fine (to PC 10.1.1.39). So far everything is functional.

Now, I have a PC2 (10.1.1.50) trying to access 10.1.1.39 using its public IP (1.1.1.39) which doesn't work.

It only works using the private IP: 10.1.1.39 and not the 1-to-1 public IP 1.1.1.39

Can you please assist and getting this to work using public and private IP both. Or this is not possible?

Thanks
