I am new to LINUX, but maybe the following will help you.
Go to
http://www.linuxgazette.com/
and see issue 18. Then take a look at "Putting Links to Your
Dynamic IP." The man wrote the script to do it so that his sister
could access his machine via the Web. Could you adapt it to your
situation?
I use my near-term goals at becoming the ISP's customer from
hell to have fun while on the way to accomplishing my goal of
becoming a good ISP techie (as you can see from the sig below). ;-)
