To belabor the obvious, remember that not all dialups are hosts; what

And for those, you aren't dynamically assigning the addresses so it is
easy to build a filter for them.

Usually.  I could see a circumstance where a small LAN was using an
ISDN dial on demand link...  You're not dynamically assigning the
address... but you _are_ dynamically assigning it to a port.
