The inbound listens on the external......the easiest way is to leave the
external on the 192.168.1.0 subnet (in case you ever have to reset the
linksys to default), and make the internal subnet different.

Ok, help me clear up something here:
Does the Inbound web listener use the external or internal IP to listen
for inbound requests? I thought it was the external.
Placing the external on a different subnet doesn't require changes to be
made to the router?
Proceeding to change external IP.
