I think you want DIVERT in there as well.  In /etc/natd.conf (or where =
you
keep your rules), you want=20

redirect_port tcp 192.168.0.13:3389 66.92.98.145:3389

Get rid of the 333 fwd rule.  Make sure there is the regular divert rule =
as
well that you get when you say YES to in /etc/rc.conf for natd.
