Correct, it is possible to set up a special redirection (depending on your firewall software), but you have to be very careful. In most cases it is better to simply use the internal ip when you're on the internal network. For those who are interested, read http://www.openbsd.org/faq/pf/rdr.html#reflect for why this is a special case and a few solutions (including the special redirect).
