I've got a new Unbuntu Apache installation sitting behind a cisco ASA with an outside address staticly mapped to the Webserver's inside address. I have an access list that allows tcp traffic for www, ftp, and ssh. Ftp & ssh work fine when using the outside address but I get:

Forbidden
You were denied access because:
Access denied by access control list.

when trying to browse to the server on the outside address. No problems using the inside address from either the same subnet or another inside subnet.

Is this because the Apache server cares that the IP being used to access it isn't the same as the one the server's bound to? If so how to get around that?

Thanks in advance.
