That is often very impractical - the logical way is often to have
interface-based rules instead of address-based rules. This is
particularly the case with laptops where the network topology on
the "outside" interface changes very often and the only sensible way
to specify rules is using the interface as designator.

Well, I think that running iptables on a laptop is also an
absolutely common case, in particular as laptops are often
running in "foreign" networks.
