You might look into ipchains and and portforwarding on your linux box.
Just setup the NT box to use the Linux box as its gateway, setup the
appropriate firewalling rules with ipchains, and setup the Linux box to
redirect any thing it hears on the Real Audio listen port to your
192.168.0.135 . I have used this several times and it seems to work
pretty good.
