What about restarting Shorewall through a dhclient-exit-hooks script?  Every
time dhclient runs, it checks for the presence of an exit-hooks script and
runs it, passing the script certain variables.  The script can check the
"reason" variable to decide if your IP address has changed and decide
whether or not to restart Shorewall.  You can also use the same technique to
re-run ddclient, thus avoiding keeping ddclient running as a daemon.

I say that all this is possible, but I lack the skills to write an example
script that actually works.  If I ever get a working sample, I''ll post
it,
but that''s a low priority for me now.
