My real ambition is always my own education, and I learned some handy 
tricks from this. :) So I'm happy with the result, even though I don't 
really need the static IP at home.

For the record and sake of completeness there's a minor correction:

The first command obviously would NOT belong in a script. You only run 
that once. The latter commands might not always need to be run, 
depending on the state of the system routing tables at the time. You 
might also want a --down script to clean up the routing, or commands 
flushing the tunnel rule and table preceding those in the --up script.

Someone on a truly dynamic IP would want a --float option, and related 
options to enable reestablishment of the tunnel after the IP changes.
