Sorry, I hit the wrong key and sent in a message pre-maturely.

If the server acknowledged a requested address, it obviously thinks
it is valid for what-ever the gateway IP was (or what-ever interface
the request came in on. Probably the most common reason for that is the
improper use of a "shared-network" in your configuration. It is hard to
say for sure without seeing the config and what the server logged when
it saw the request.
