Problem accessing another public ip in same subnet

Hi,

I have searched around for a previous post regarding this but can't find an issue similar to mine (or I'm just too stupid to understand that it is )

I have a Cisco 5505 at a small business that I help. The problem is that the ISP are providing public IPs to multiple customers in a /24 subnet. The ASA has a single public IP configured 8.8.8.8 (not really, just for the examples sake) with a subnet mask of 255.255.255.0.

The webserver I have to access is not managed by me and is located in a different location (same town though) has 8.8.8.115, it is located in the same subnet as the ASA.

How would I make this work? I have tried to configure a static arp entry for the web server but it just won't work. If i place a computer directly on the outside interface I have no problem accessing the web server.

I am running ASA version 8.2, but I could upgrade if it would help me solve the problem.

Any help with this issue is much appreciated.

Thank you for taking the time to answer but this has nothing to do with my issue. I have tried to clarify further in an earlier post answering Jons post.

I think Swaraj is correct.

I was just trying to clarify the topology to make sure this is how you have it setup.
