If you're using ppp, just use the -alias switch.  Things like
changing IP numbers are automatically dealt with.

If you really need to use natd, you can give it the -dynamic
switch.  It tells natd to read the routing socket so that it
notices changes to the interfaces IP number (you must also use
the -n option).  The -dynamic switch was broken between version
1.4 & 1.8 of natd, but the version committed to the main source
tree yesterday (v1.8) should work ok.
